Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business Time Warner Inc. (“Time Warner” or the “Company”) is a leading media and entertainment company, whose businesses include television networks, and film and TV entertainment. Time Warner classifies its operations into three reportable segments: Turner : consisting principally of cable networks and digital media properties; Home Box Office : consisting principally of premium pay television services and a service that delivers video content to consumers over the internet (“OTT service”) domestically and premium pay, basic tier television and OTT services internationally; and Warner Bros. : consisting principally of television, feature film, home video and videogame production and distribution. Basis of Presentation Basis of Consolidation The consolidated financial statements include all the assets, liabilities, revenues, expenses and cash flows of entities in which Time Warner has a controlling interest (“subsidiaries”). Intercompany accounts and transactions between consolidated entities have been eliminated in consolidation. Reclassifications Certain reclassifications have been made to the prior year financial information to conform to the December 31, 2016 presentation. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and footnotes thereto. Actual results could differ from those estimates. Significant estimates and judgments inherent in the preparation of the consolidated financial statements include accounting for asset impairments, multiple-element transactions, allowances for doubtful accounts, depreciation and amortization, the determination of ultimate revenues as it relates to amortization or impairment of capitalized film and programming costs and participations and residuals, home video and videogame product returns, business combinations, pension and other postretirement benefits, equity-based compensation, income taxes, contingencies, litigation matters, reporting revenue for certain transactions on a gross versus net basis, and the determination of whether the Company should consolidate certain entities. Venezuela Currency Certain of the Company's divisions conduct business with third parties located in Venezuela and, as a result, the Company holds net monetary assets denominated in Venezuelan Bolivares Fuertes (“VEF”) that primarily consist of cash and accounts receivable. Because of Venezuelan government-imposed restrictions on the exchange of VEF into foreign currency in Venezuela, the Company has not been able to convert VEF earned in Venezuela into U.S. Dollars through the Venezuelan government’s foreign currency exchange systems. As of December 31, 2014, there were three legal foreign currency exchange systems administered by the Venezuelan government, each with a different exchange rate: (i) the fixed official government rate as published by the Central Bank of Venezuela, (ii) the variable, auction-based SICAD 1 rate, and (iii) the variable, transaction-based SICAD 2 rate. Prior to December 31, 2014, the Company used the official government exchange rate to remeasure its VEF-denominated transactions and balances. During the fourth quarter of 2014, the Company considered information about the companies that were able to access the three exchange systems during 2014 and the fact that the SICAD 1 and SICAD 2 exchanges continued to operate, as well as the state of the Venezuelan economy, which had entered a recession. Based on these factors, as of December 31, 2014, the Company concluded that the SICAD 2 exchange rate was the most appropriate legal exchange rate for the Company's business activities conducted in VEF. Accordingly, beginning on December 31, 2014, the Company began using the SICAD 2 rate to remeasure its VEF-denominated transactions and balances and, for the three months and year ended December 31, 2014, recognized a pretax foreign exchange loss of $173 million in the Consolidated Statement of Operations. On February 10, 2015, Venezuelan government officials announced changes to Venezuela’s foreign currency exchange system. Those changes included the elimination of the SICAD 2 exchange due to the merger of the SICAD 1 and SICAD 2 exchanges into a single SICAD exchange as well as the creation of the Simadi exchange, which is a free market foreign currency exchange. On their initial date of activity, the exchange rates published by the Central Bank of Venezuela were 12 VEF to each U.S. Dollar for the SICAD exchange and 170 VEF to each U.S. Dollar for the Simadi exchange. Given the restrictions associated with the official government rate and the SICAD exchange, starting on February 10, 2015, the Company began to use the Simadi exchange rate to remeasure its VEF-denominated transactions and balances and recognized a pretax foreign exchange loss of $22 million in the Consolidated Statement of Operations during the quarter ended March 31, 2015. Approximately $15 million of such loss related to cash balances. Accounting Guidance Adopted in 2016 Equity Method of Accounting In March 2016, guidance was issued that changes the requirements for equity method accounting when an investment qualifies for use of the equity method. The guidance (i) eliminates the need to retroactively apply the equity method of accounting upon qualifying for such treatment, (ii) requires that the cost of acquiring an additional interest in an investee be added to the basis of the previously held interest and (iii) requires that unrealized holding gains or losses for available-for-sale equity securities that qualify for the equity method of accounting be recognized in earnings at the date the investment becomes qualified for use of the equity method of accounting. The Company adopted this guidance on January 1, 2016 on a prospective basis and it did not impact the Company’s consolidated financial statements. Accounting Guidance Not Yet Adopted Simplifying the Accounting for Goodwill Impairment In January 2017, guidance was issued to simplify the accounting for goodwill impairment. The guidance removes the second step of the goodwill impairment test, which requires that a hypothetical purchase price allocation be performed to determine the amount of impairment, if any. Under this new guidance, a goodwill impairment charge will be based on the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance will become effective on a prospective basis for the Company on January 1, 2020 and is not expected to have a material impact on the Company’s consolidated financial statements. Definition of a Business In January 2017, guidance was issued that changes the definition of a business for accounting purposes. Under the new guidance, an entity first determines whether substantially all of the fair value of a set of assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set of assets is not deemed to be a business. If the threshold is not met, the entity then evaluates whether the set of assets meets the requirement to be deemed a business, which at a minimum, requires there to be an input and a substantive process that together significantly contribute to the ability to create outputs. The guidance will become effective on a prospective basis for the Company on January 1, 2018 and is not expected to have a material impact on the Company’s consolidated financial statements. Restricted Cash In November 2016, guidance was issued that requires that a statement of cash flows present the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total cash amounts shown on the statement of cash flows. The guidance will become effective on a retrospective basis for the Company on January 1, 2018 and is not expected to have a material impact on the Company’s consolidated financial statements. Intra-Entity Transfers of Assets Other than Inventory In October 2016, guidance was issued that requires entities to recognize the income tax consequences of an intercompany transfer of an asset other than inventory when the transfer occurs, rather than deferring the income tax consequences of the intercompany transfer of assets until the asset has been sold to a third party. The guidance will become effective on a modified retrospective basis for the Company on January 1, 2018 and is not expected to have a material impact on the Company’s consolidated financial statements. Classification of Certain Cash Receipts and Cash Payments In August 2016, guidance was issued that clarifies the presentation of certain cash receipts and payments in a company’s statement of cash flows. The guidance primarily relates to the classification of cash flows associated with certain (i) debt transactions, (ii) contingent consideration arrangements related to business combinations, (iii) insurance claims and policies, (iv) distributions received from equity method investees and (v) securitization transactions. The guidance will become effective on a retrospective basis for the Company on January 1, 2018 and is not expected to have a material impact on the Company’s consolidated financial statements. Share-Based Payments In March 2016, guidance was issued that changes the reporting for certain aspects of share-based payments. One aspect of the guidance, which became effective on a prospective basis on January 1, 2017, requires that the income tax effects of share-based awards be recognized in the income statement when the awards vest or are settled. Under the previous guidance, excess tax benefits and deficiencies were recognized in Additional paid-in capital in the Consolidated Balance Sheet. For the years ended December 31, 2016 and 2015 , the amount of excess tax benefits, net of deficiencies, recognized in Additional paid-in capital was $82 million and $150 million , respectively. In addition, because excess tax benefits are no longer recognized in Additional paid-in capital, such amounts are no longer included in the determination of assumed proceeds in applying the treasury stock method when computing earnings per share. Another aspect of the new guidance, which the Company adopted on a prospective basis on January 1, 2017, requires that excess tax benefits be classified as a cash flow from operating activities in the Consolidated Statement of Cash Flows. Under the previous guidance, excess tax benefits were classified as a cash flow from financing activities. Excess tax benefits presented as a cash flow from financing activities were $88 million , $151 million , and $179 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. The other aspects of this new guidance are not expected to have a material effect on the Company’s consolidated financial statements. Accounting for Leases In February 2016, guidance was issued regarding accounting for leases. The main difference between the current guidance and the new guidance is the recognition by the lessee of lease assets and liabilities for those leases it classified as operating leases under the current guidance. Under the new guidance, the recognition, measurement and presentation of expenses and cash flows arising from a lease as well as the lessor accounting model have not significantly changed from current guidance. This guidance also requires qualitative and quantitative disclosures of key information about leasing arrangements. The new guidance will become effective on a modified retrospective basis for the Company on January 1, 2019. The Company is still evaluating the impact of the new guidance on its consolidated financial statements. Because the Company is a party to more than 2,000 operating leases with future minimum rental commitments of $1.154 billion , it expects that the impact of recognizing lease assets and liabilities for these operating leases will be significant to the Company’s Consolidated Balance Sheet. Recognition and Measurement of Financial Assets and Liabilities In January 2016, guidance was issued that makes limited changes to the accounting for financial instruments. The changes primarily relate to (i) the requirement to measure equity investments in unconsolidated subsidiaries, other than those accounted for under the equity method of accounting, at fair value, with changes in the fair value recognized in earnings, (ii) an alternative approach for the measurement of equity investments that do not have a readily determinable fair value, (iii) the elimination of the other-than-temporary impairment model and its replacement with a requirement to perform a qualitative assessment to identify the impairment of equity investments, and a requirement to recognize impairment losses in earnings based on the difference between the fair value and the carrying value of the equity investment, (iv) the elimination of the requirement to disclose the methods and significant assumptions used to estimate the fair value of financial instruments measured at amortized cost, (v) the addition of a requirement to use the exit price concept when measuring the fair value of financial instruments for disclosure purposes and (vi) the addition of a requirement to present financial assets and financial liabilities separately in the notes to the financial statements, grouped by measurement category (e.g., fair value, amortized cost, lower of cost or market) and by form of financial asset (e.g., loans, securities). This guidance will become effective for the Company on January 1, 2018. The Company does not expect the new guidance to have a material impact on its consolidated financial statements. Revenue Recognition In May 2014, guidance was issued that establishes a new revenue recognition framework in GAAP for all companies and industries. The core principle of the new guidance is that an entity should recognize revenue from the transfer of promised goods or services to customers in an amount that reflects the consideration the entity expects to receive for those goods or services. The guidance includes a five-step framework to determine the timing and amount of revenue to recognize related to contracts with customers. In addition, this guidance requires new or expanded disclosures related to the judgments made by companies when following this framework. Based on the current guidance, the new framework will become effective on either a full or modified retrospective basis for the Company on January 1, 2018. Subsequent to the issuance of the May 2014 guidance, several clarifications and updates have been issued by the FASB on this topic, the most recent of which was issued in December 2016. Many of these clarifications and updates to the guidance, as well as a number of interpretive issues, apply to companies in the media and entertainment industry. The Company has made significant progress toward completing its assessment of the impact of adopting this new guidance, and the Company is finalizing its implementation plan. The Company currently does not believe that the adoption of the new guidance will have a material impact on the Company’s financial statements, principally because the Company does not expect significant changes in the way it will record subscription revenue, advertising revenue, and a significant portion of its content revenue. However, it is possible that the Company’s evaluation of the expected impact of the new guidance on certain transactions could change if there are additional interpretations of the new revenue guidance that are different from the Company’s preliminary conclusions. Although the Company currently does not expect the impact of adopting the new guidance to be material, there are several areas where the Company’s revenue recognition is expected to change as compared with historical GAAP. The more significant of these areas are as follows: i. Renewals of Licenses of Intellectual Property - Under guidance currently in effect, when the term of an existing license agreement is extended, without any other changes to the provisions of the license, revenue for the renewal period is recognized on the date the renewal is agreed to contractually. Under the new guidance, revenue for the renewed license term will not be recognized until the date the renewal term begins. This change will result in delayed revenue recognition as compared with current revenue recognition guidance. The Company expects that this change will primarily impact the Warner Bros. segment, but it will also, to a lesser degree, impact the Home Box Office and Turner segments. ii. License of Content Library - Under guidance currently in effect, when a company licenses a completed library of content and agrees to refresh the library with new content as it becomes available, and the licensee is not entitled to a refund if no further library titles are delivered, revenue is recognized once access to the library is granted to the licensee. Under the new guidance, because there is an implicit obligation for the company to refresh the library with additional content in the future, the company will need to estimate the additional content it will deliver in the future and allocate a portion of the transaction price to that content. As compared with current guidance, this results in a deferral of a portion of the transaction price until delivery of future library content. The Company expects this change will primarily impact the Home Box Office segment. iii. Licenses of Symbolic Intellectual Property - Certain intellectual property, such as brands, tradenames and logos, is categorized in the new guidance as symbolic. An assumption inherent in the new guidance is that a licensee’s ability to derive benefit from a license of symbolic intellectual property depends on the licensor continuing to support or maintain the intellectual property throughout the license term. Accordingly, under the new guidance, revenue from licenses of symbolic intellectual property is recognized over the corresponding license term. In certain arrangements where the Company has no remaining performance obligations, under the guidance currently in effect, revenue from licenses of symbolic intellectual property is recognized at the inception of the license term. Therefore, the new guidance will result in a deferral of revenue recognition as compared to current guidance. This change will primarily impact the Warner Bros. segment. The evaluation of the impact of the new guidance on certain other transactions is still in process; however, the Company does not expect the completion of that evaluation to impact the Company’s conclusion that the adoption will not have a material impact on the Company’s financial statements. The Company currently expects to adopt the standard in 2018 using the modified retrospective method of adoption. However, the transition method ultimately selected could be affected by the Company’s pending merger with AT&T Inc. (“AT&T”) if the merger closes prior to the adoption of the new guidance. For more information regarding the AT&T merger, see Note 2. Summary of Critical and Significant Accounting Policies The following is a discussion of each of the Company’s critical accounting policies, including information and analysis of estimates and assumptions involved in their application, and other significant accounting policies. The Securities and Exchange Commission (“SEC”) considers an accounting policy to be critical if it is important to the Company’s financial condition and results of operations and if it requires significant judgment and estimates on the part of management in its application. The development and selection of these critical accounting policies have been determined by Time Warner’s management and the related disclosures have been reviewed with the Audit and Finance Committee of the Board of Directors of the Company. Due to the significant judgment involved in selecting certain of the assumptions used in these areas, it is possible that different parties could choose different assumptions and reach different conclusions. The Company considers the policies relating to the following matters to be critical accounting policies: • Impairment of Goodwill and Intangible Assets (see pages 89 to 90); • Film and Television Production Cost Recognition, Participations and Residuals and Impairments (see pages 93 to 94); • Licensed Programming Inventory Cost Recognition and Impairment (see pages 94 to 95); • Gross versus Net Revenue Recognition (see page 93); • Sales Returns and Pricing Rebates (see page 93); and • Income Taxes (see page 97). Cash and Equivalents Cash equivalents consist of investments that are readily convertible into cash and have original maturities of three months or less. Cash equivalents are carried at cost, which approximates fair value. The Company monitors concentrations of credit risk with respect to Cash and equivalents by placing such balances with higher quality financial institutions or investing such amounts in liquid, short-term, highly-rated instruments or investment funds holding similar instruments. As of December 31, 2016 , the majority of the Company’s Cash and equivalents were invested with banks with a credit rating of at least A and in Rule 2a-7 money market mutual funds. At December 31, 2016 , the Company did not have more than $500 million invested in any single bank or money market mutual fund. Allowance for Doubtful Accounts The Company monitors customer credit risk related to accounts receivable, including unbilled trade receivables primarily related to the distribution of television product. Significant judgments and estimates are involved in evaluating if such amounts will ultimately be fully collected. Each of the Company’s businesses maintains a comprehensive approval process prior to issuing credit to third-party customers. Counterparties that are determined to be of a higher risk are evaluated to assess whether the credit terms previously granted to them should be modified. The Company monitors customers’ accounts receivable aging, and a provision for estimated uncollectible amounts is maintained based on customer payment levels, historical experience and management’s views on trends in the overall receivable agings. In addition, for larger accounts, the Company performs analyses of risks on a customer-specific basis. At December 31, 2016 and 2015 , total reserves for doubtful accounts were approximately $193 million and $180 million , respectively. For the years ended December 31, 2016 and 2015 , the Company recognized $38 million and $63 million of bad debt expense, respectively. For the year ended December 31, 2014 , the Company recognized $20 million of income related to bad debt primarily due to the reversal of a reserve related to a Warner Bros. receivable. Consolidation Time Warner consolidates all entities in which it has a controlling voting interest and all variable interest entities (“VIEs”) in which the Company is deemed to be the primary beneficiary. Entities determined to be VIEs primarily consist of HBO Latin America Group (“HBO LAG”) and Hudson Yards North Tower Holdings LLC (“HYNTH”), the limited liability company involved in the construction and development of the Company’s new headquarters building at Hudson Yards. HBO LAG is a VIE because the Company’s ownership interest ( 88% ) and voting rights ( 50% ) in this entity are disproportionate. The Company has determined that it is not the primary beneficiary of this VIE because voting control is shared equally with the other investor and therefore the Company does not have the power to direct the activities that most significantly impact the entity’s economic performance. As of December 31, 2016 and December 31, 2015 , the Company’s aggregate investment in HBO LAG was $535 million and $558 million , respectively. The investment in HBO LAG is intended to enable the Company to more broadly leverage its programming and digital strategy in the territories served and to capitalize on growing opportunities in such territories. The Company provides programming as well as certain services, including distribution, licensing and technological and administrative support, to HBO LAG. HBO LAG is financed through cash flows from its operations, and the Company is not obligated to provide HBO LAG with any additional financial support. In addition, the assets of HBO LAG are not available to settle the Company’s obligations. During 2015, the Company finalized agreements related to the construction and development of office and studio space in the Hudson Yards development on the west side of Manhattan in order to move its Corporate headquarters and New York City-based employees to the new space. The Company will fund its proportionate share of the costs for the construction and development through HYNTH, a limited liability company that is controlled by the developer of the Hudson Yards development project and managed by an affiliate of the developer. HYNTH is a VIE because the equity investment at risk is not sufficient to permit HYNTH to carry on its activities without additional subordinated financial support. The Company is not the primary beneficiary of HYNTH because it does not have the power to direct the activities that most significantly impact the entity’s economic performance. As of December 31, 2016 and 2015 , the Company’s investment in HYNTH, which is accounted for under the equity method of accounting, was approximately $729 million and $438 million , respectively. Based on construction cost estimates and space projections as of December 31, 2016 , the Company expects to invest an additional $1.4 billion , excluding interest, in the Hudson Yards development project through 2019. Investments Investments in common stock in companies in which Time Warner has significant influence, but less than a controlling voting interest, are accounted for using the equity method. Significant influence is generally presumed to exist when Time Warner owns between 20% and 50% of the voting interests in the investee, holds substantial management rights or holds an interest of less than 20% in an investee that is a limited liability partnership or limited liability corporation that is treated as a flow-through entity. Under the equity method of accounting, only Time Warner’s investment in and amounts due to and from the equity investee are included in the Consolidated Balance Sheet; only Time Warner’s share of the investee’s earnings (losses) is included in the Consolidated Statement of Operations; and only the dividends, cash distributions, loans or other cash received from the investee, additional cash investments, loan repayments or other cash paid to the investee are included in the Consolidated Statement of Cash Flows. If previous equity method losses have reduced the carrying value of the Company’s equity method investment to zero, the Company continues to record its share of equity method losses to the extent it has (i) other investments in the investee, (ii) guaranteed obligations of the investee or (iii) committed to provide further financial support for the investee. Investments in companies in which Time Warner does not have a controlling voting interest or over which it is unable to exert significant influence are generally accounted for at fair value if the investments are publicly traded. If the investment or security is not publicly traded, the investment is accounted for at cost. Unrealized gains and losses on investments accounted for at fair value are reported, net of tax, in Accumulated other comprehensive loss, net. Dividends and other distributions of earnings from investments in companies in which Time Warner does not have a controlling voting interest or over which it is unable to exert significant influence are included in Other loss, net, when declared. For more information, see Notes 4 and 5. The company regularly reviews its investments for impairment. See “Asset Impairments” below for additional information. Foreign Currency Translation Financial statements of subsidiaries operating outside the United States whose functional currency is not the U.S. Dollar are translated at the rates of exchange on the balance sheet date for assets and liabilities and at average rates of exchange for revenues and expenses during the period. Translation gains or losses on assets and liabilities are included as a component of Accumulated other comprehensive loss, net. Derivative Instruments The Company uses derivative instruments principally to manage the risk associated with movements in foreign currency exchange rates, and recognizes all derivative instruments on the Consolidated Balance Sheet at fair value. Changes in fair value of derivative instruments that qualify for hedge accounting will either be offset against the change in fair value of the hedged assets or liabilities through earnings or recognized in shareholders’ equity as a component of Accumulated other comprehensive loss, net, until the hedged item is recognized in earnings, depending on whether the derivative instrument is being used to hedge changes in fair value or cash flows. For qualifying hedge relationships, the Company excludes the impact of forward points or option premiums from its assessment of hedge effectiveness and recognizes changes in the fair value of a derivative instrument due to forward points or option premiums in Other income (loss), net each quarter. The ineffective portion of a derivative instrument’s change in fair value is immediately recognized in earnings. For those derivative instruments that do not qualify for hedge accounting, changes in fair value are recognized immediately in earnings. See Note 8 for additional information regarding derivative instruments held by the Company and risk management strategies. Property, Plant and Equipment Property, plant and equipment are stated at cost. Additions to property, plant and equipment generally include material, labor and overhead. Time Warner also capitalizes certain costs associated with coding, software configuration, upgrades and enhancements incurred for the development of internal use software. Depreciation is recorded on a straight-line basis over estimated useful lives. Leasehold improvements are depreciated over the lesser of the estimated useful life of the improvement or the term of the applicable lease. Time Warner periodically evaluates the depreciation periods of property, plant and equipment to determine whether a revision to its estimates of useful lives is warranted. Property, plant and equipment, including capital leases, consist of (millions): December 31, Estimated Useful Lives 2016 2015 Land (a) $ 268 $ 273 n/a Buildings and improvements 1,641 1,619 7 to 30 years Capitalized software costs 2,029 1,958 3 to 7 years Furniture, fixtures and other equipment (b) 3,017 3,069 3 to 10 years 6,955 6,919 Accumulated depreciation (4,445 ) (4,323 ) Total $ 2,510 $ 2,596 _________________________ (a) Land is not depreciated. (b) Includes $183 million and $174 million of construction in progress as of December 31, 2016 and 2015 , respectively. Intangible Assets Time Warner has a significant number of intangible assets, including acquired film and television libraries and other copyrighted products and tradenames. Time Warner does not recognize the fair value of internally generated intangible assets. Intangible assets acquired in business combinations are recorded at the acquisition date fair value in the Company’s Consolidated Balance Sheet. Acquired film libraries are amortized using the film forecast computation model. For more information, see “Film and Television Production Cost Recognition, Participations and Residuals and Impairments” and Note 3. Asset Impairments Investments The Company’s investments consist of (i) investments carried at fair value, including available-for-sale securities and certain deferred compensation-related investments, (ii) investments accounted for using the cost method of accounting and (iii) investments accounted for using the equity method of accounting.

Subsequent Event Business Combinations [Abstract]
MERGER AGREEMENT WITH AT&T	MERGER AGREEMENT WITH AT&T On October 22, 2016, Time Warner entered into an Agreement and Plan of Merger (the “Merger Agreement”) with AT&T. The Merger Agreement provides for the merger of a newly formed wholly owned subsidiary of AT&T with and into Time Warner, with Time Warner continuing as the surviving company in the merger. Immediately thereafter, Time Warner will merge with and into a limited liability company formed by AT&T, which will continue as the surviving entity and a wholly owned subsidiary of AT&T. The Merger Agreement was unanimously approved by all members of Time Warner’s and AT&T’s board of directors. Time Warner shareholders adopted the Merger Agreement at a special meeting of shareholders on February 15, 2017. Subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, upon consummation of the merger, each share of the Company’s common stock will be converted into the right to receive $53.75 in cash and a specified number of shares of AT&T stock, as set forth in the Merger Agreement and determined by reference to the average of the volume weighted averages of the trading price of AT&T common stock on the New York Stock Exchange (“NYSE”) on each of the 15 consecutive NYSE trading days ending on and including the trading day that is three trading days prior to the closing of the merger (the “Average Stock Price”). The stock portion of the per share consideration will be subject to a collar such that if the Average Stock Price is between $37.411 and $41.349 , Time Warner shareholders will receive shares of AT&T stock equal to $53.75 in value for each share of Time Warner common stock. If the Average Stock Price is below $37.411 , Time Warner shareholders will receive 1.437 AT&T shares for each share of Time Warner common stock. If the Average Stock Price is an amount greater than $41.349 , Time Warner shareholders will receive 1.300 AT&T shares for each share of Time Warner common stock. The merger is conditioned on the receipt of certain antitrust and other required regulatory consents. The merger is expected to close before year-end 2017. Should Time Warner terminate the Merger Agreement in specified circumstances, Time Warner may be required to pay AT&T a termination fee equal to $1.725 billion if Time Warner enters into or consummates an alternative transaction with a third party following such termination of the Merger Agreement.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND INTANGIBLE ASSETS Time Warner has a significant number of intangible assets, including acquired film and television libraries and other copyrighted products and tradenames. Certain intangible assets are deemed to have finite lives and, accordingly, are amortized over their estimated useful lives, while others are deemed to be indefinite-lived and therefore are not amortized. Goodwill and indefinite-lived intangible assets, primarily certain tradenames, are tested annually for impairment during the fourth quarter, or earlier upon the occurrence of certain events or substantive changes in circumstances. Goodwill The following summary of changes in the Company’s Goodwill during the years ended December 31, 2016 and 2015 , by reportable segment and in total, is as follows (millions): Turner Home Box Office Warner Bros. Total Balance at December 31, 2014 $ 13,956 $ 7,433 $ 6,176 $ 27,565 Acquisitions, dispositions and adjustments, net 176 — 8 184 Translation adjustments (24 ) — (36 ) (60 ) Balance at December 31, 2015 $ 14,108 $ 7,433 $ 6,148 $ 27,689 Acquisitions, dispositions and adjustments, net 16 — 85 101 Translation adjustments 1 — (39 ) (38 ) Balance at December 31, 2016 $ 14,125 $ 7,433 $ 6,194 $ 27,752 The carrying amount of goodwill for all periods presented was net of accumulated impairments of $13.338 billion and $4.091 billion at the Turner segment and the Warner Bros. segment, respectively. The performance of the Company’s annual impairment analysis did no t result in any impairments of Goodwill for any of the years in the three-year period ended December 31, 2016 . Refer to Note 1 for a discussion of the 2016 annual impairment test. The increase in Goodwill at the Warner Bros. segment for the year ended December 31, 2016 was primarily related to several insignificant acquisitions made during 2016, offset in part by the sale of its Flixster business. The increase in Goodwill at the Turner segment for the year ended December 31, 2015 was primarily related to the acquisition of iStreamPlanet Co., LLC (“iStreamPlanet”). See Note 4 for additional information. Intangible Assets The Company recorded noncash impairments of intangible assets during the years ended December 31, 2016 , 2015 and 2014 , by reportable segment, as follows (millions): Year Ended December 31, 2016 2015 2014 Turner $ 25 $ 1 $ 1 Home Box Office — — 4 Warner Bros. — — 13 Time Warner $ 25 $ 1 $ 18 The Company’s intangible assets subject to amortization and related accumulated amortization consisted of the following (millions): December 31, 2016 December 31, 2015 Gross Accumulated Amortization(a) Net Gross Accumulated Amortization(a) Net Film library $ 3,432 $ (2,914 ) $ 518 $ 3,432 $ (2,776 ) $ 656 Brands, tradenames and other intangible assets 702 (437 ) 265 716 (423 ) 293 Total $ 4,134 $ (3,351 ) $ 783 $ 4,148 $ (3,199 ) $ 949 _________________________ (a) The film library has a weighted-average remaining life of approximately 4 years and is amortized using a film forecast computation methodology. Amortization of brands, tradenames and other intangible assets subject to amortization is provided generally on a straight-line basis over their respective useful lives. The Company recorded amortization expense of $190 million in 2016 compared to $189 million in 2015 and $202 million in 2014 . Amortization expense may vary in the future as acquisitions, dispositions and impairments, if any, occur and as purchase price allocations are finalized. The Company’s estimated amortization expense for the succeeding five years ended December 31 is as follows (millions): 2017 2018 2019 2020 2021 Estimated amortization expense $ 181 $ 172 $ 161 $ 145 $ 40

Acquisitions and Dispositions [Abstract]
DISPOSITIONS AND ACQUISITIONS	DISPOSITIONS AND ACQUISITIONS Dispositions Separation of Time Inc. As discussed in Note 1, the Time Separation was completed on June 6, 2014. The Time Separation was effected as a pro rata dividend of all shares of Time Inc. common stock held by Time Warner in a spin-off to Time Warner stockholders. With the completion of the Time Separation, the Company disposed of the Time Inc. segment in its entirety and ceased to consolidate its assets, liabilities and results of operations in the Company’s consolidated financial statements. Accordingly, the Company has presented the financial position and results of operations of its former Time Inc. segment as discontinued operations in the consolidated financial statements for all periods presented. In connection with the Time Separation, the Company received $1.4 billion from Time Inc., consisting of proceeds relating to Time Inc.’s acquisition of the IPC publishing business in the U.K. from a wholly-owned subsidiary of Time Warner and a special dividend.

CME Central European Media Enterprises Ltd. (“CME”) is a publicly-traded broadcasting company operating leading networks in six Central and Eastern European countries. As of December 31, 2016 , the Company had an approximate 47% voting interest in CME’s common stock and an approximate 76% economic interest in CME on a diluted basis. As of December 31, 2016 , the Company owned 61.4 million shares of CME’s Class A common stock and 1 share of Series A convertible preferred stock, which is convertible into 11.2 million shares of CME’s Class A common stock and votes with the Class A common stock on an as-converted basis. The Company accounts for its investment in CME’s Class A common stock and Series A convertible preferred stock under the equity method of accounting. Although the book value of the Company’s equity method investment in CME has been reduced to zero through the recognition of equity method losses, the Company has continued to record equity method losses because it has guaranteed an aggregate amount of €955 million of CME’s obligations (as described below). The amount of such equity method losses at December 31, 2016 was $123 million and is presented in Other noncurrent liabilities on the Consolidated Balance Sheet. In addition, in connection with these guarantees, the Company recognized a liability at the inception of each respective arrangement based on the estimated fair value of the applicable guarantee. At December 31, 2016, the carrying value of liabilities associated with such guarantees was $183 million , which is also included in Other noncurrent liabilities on the Consolidated Balance Sheet. As of December 31, 2016 , the Company owned all of the outstanding shares of CME’s Series B convertible redeemable preferred shares, which are non-voting and may be converted into 105.2 million shares of CME’s Class A common stock at the Company’s option. The Series B convertible redeemable preferred shares accrete in value until June 24, 2018 at an annual rate of 3.75% compounded quarterly. The Company accounts for its investment in CME’s Series B convertible redeemable preferred shares under the cost method of accounting. As of December 31, 2016 , the Company held 101 million warrants each to purchase one share of CME Class A common stock. The warrants, which became exercisable in May 2016, have a four -year term that expires in May 2018, an exercise price of $1.00 per share and do not contain any voting rights. The warrants are carried at fair value in the Consolidated Balance Sheet, which at December 31, 2016 , was $159 million . CME Rights Offering and Related Transactions On May 2, 2014, pursuant to a rights offering by CME, Time Warner acquired approximately 2.8 million units, each consisting of $100 principal amount of CME’s 15% senior secured notes due 2017 (the “Senior Secured Notes”) and 21 unit warrants, with each unit warrant entitling the Company to purchase one share of CME Class A common stock. In addition, Time Warner acquired 581,533 units in a private offering, and CME issued warrants to Time Warner to purchase an additional 30 million shares of Class A common stock. The Senior Secured Notes were repaid in April 2016 as more fully described below. CME Revolving Credit Facility and Term Loan Provided by Time Warner On May 2, 2014, Time Warner provided CME a $115 million revolving credit facility (the “CME Revolving Credit Facility”) and a $30 million term loan (the “TW Term Loan”), each with a maturity date of December 1, 2017. The TW Term Loan bore interest at a rate of 15.0% per annum, paid semi-annually either fully in cash or by adding such amount to the principal amount of the loan. The TW Term Loan was repaid in April 2016 as more fully described below. On February 19, 2016, Time Warner and CME agreed to amend and restate the CME Revolving Credit Facility to reduce the size of the facility to $50 million as of January 1, 2018 and to extend its term from December 2017 to February 2021. Amounts outstanding under the CME Revolving Credit Facility bear interest at a rate based on CME’s net leverage. Beginning in April 2016, CME must pay a portion of the interest for each applicable quarterly interest period in cash and may, at CME’s option, pay the remainder in kind by adding such amount to the outstanding principal amount of the CME Revolving Credit Facility. The CME Revolving Credit Facility also contains a commitment fee on the average daily unused amount under the facility of 0.50% per annum. As of December 31, 2016 , there were no amounts outstanding under the CME Revolving Credit Facility. Time Warner Guarantees of CME Debt On November 14, 2014, Time Warner and CME entered into an agreement pursuant to which Time Warner agreed to assist CME in refinancing $261 million aggregate principal amount of its Senior Convertible Notes due 2015 (“2015 Notes”) and €240 million aggregate principal amount of its Senior Notes due 2017 (“2017 Notes”). In connection with this agreement, CME entered into a credit agreement (the “2014 Credit Agreement”) with third-party financial institutions the same day for a €251 million senior unsecured term loan (the “2014 Term Loan”) that was funded in December 2014 and had a maturity date of November 1, 2017. Time Warner has guaranteed CME’s obligations under the 2014 Credit Agreement for a fee equal to 8.5% less the interest rate on the term loan. The fee is payable to Time Warner semi-annually in cash or in kind at CME’s option. CME used the proceeds of the term loan to redeem the 2017 Notes. CME also entered into unsecured interest rate hedge arrangements to protect against changes in the interest rate on the term loan during its term. Time Warner has also guaranteed CME’s obligations under the hedge arrangements. On February 19, 2016, CME entered into an amendment to extend the maturity of the 2014 Term Loan from November 1, 2017 to November 1, 2018. On September 30, 2015, CME entered into a credit agreement (the “2015 Credit Agreement”) with third-party financial institutions for a €235 million senior unsecured term loan that was funded in November 2015 and matures on November 1, 2019. Time Warner has guaranteed CME’s obligations under the 2015 Credit Agreement for an annual fee equal to 8.5% less the interest rate on the term loan, to be paid to Time Warner semi-annually in cash or in kind at CME’s option. CME used the proceeds of the term loan to repay the $261 million aggregate principal amount of the 2015 Notes at maturity on November 15, 2015. As consideration for assisting CME in refinancing the 2015 Notes, Time Warner also earned a commitment fee of $9 million , which accrues interest at a rate of 8.5% . In November 2015, CME entered into unsecured interest rate hedge arrangements to protect against changes in the interest rate on the term loan during its term. Time Warner has guaranteed CME’s obligations under the hedge arrangements. On February 19, 2016, CME Media Enterprises B.V. (“CME BV”), a subsidiary of CME, entered into a credit agreement (the “2016 Credit Agreement”) with third-party financial institutions for a €469 million senior unsecured term loan (the “2016 Term Loan”) that was funded in April 2016 and matures on February 19, 2021. Time Warner has guaranteed CME BV’s obligations under the 2016 Credit Agreement for a fee equal to a rate based on CME’s net leverage, which was 9% as of December 31, 2016, less the interest rate on the 2016 Term Loan, which was 1.78% as of December 31, 2016, to be paid to Time Warner semi-annually. CME BV must pay a portion of the fee in cash and may, at CME BV’s option, pay the remainder in cash or in kind. In April 2016, CME used cash on hand and the proceeds of the 2016 Term Loan to repay in their entirety both its Senior Secured Notes and the TW Term Loan. Time Warner received approximately $485 million in connection with CME’s repayment of the Senior Secured Notes and the TW Term Loan. As consideration for assisting CME in refinancing its debt due in 2017, Time Warner earned a fee equal to 1% of the aggregate principal amount of the 2016 Term Loan borrowed at funding. Prior to the funding, CME BV entered into unsecured interest rate hedge arrangements to protect against changes in the interest rate on the 2016 Term Loan during its term, and Time Warner has guaranteed CME BV’s obligations under such arrangements. In connection with the transactions entered into on February 19, 2016, the Company recorded a pretax gain of $95 million in Investment gains (losses), net in the Consolidated Statement of Operations in the second quarter of 2016. Additionally, when recognizing CME’s results in the second quarter of 2016 under the equity method of accounting, the Company recorded a pretax charge of $150 million in Other loss, net in the Consolidated Statement of Operations related to the transactions entered into on February 19, 2016. Pursuant to the terms of all of CME’s outstanding senior debt, a change of control of Time Warner provides the administrative agent and/or lenders of this debt the right to declare the debt immediately due and payable. If that were to occur, Time Warner would be obligated under the terms of its guarantees to pay the full amount of the debt, subject to reimbursement from CME on the scheduled maturity dates for the debt in 2018, 2019 and 2021. Equity-Method Investments At December 31, 2016 , investments accounted for using the equity method included the Company’s investments in the Class A common stock and Series A convertible preferred stock of CME, HBO LAG ( 88% owned), Hulu, HYNTH and certain other ventures that are generally 20% to 50% owned. Cost-Method Investments The Company’s cost-method investments include its investment in the Series B convertible redeemable preferred shares of CME as well as its investments in other early- to mid-stage non-public entities that are of strategic relevance to Time Warner’s businesses. The Company uses available qualitative and quantitative information to evaluate all cost-method investments for impairment at least quarterly. Gain on Sale of Investments, Net For the years ended December 31, 2016 , 2015 and 2014 , the Company recognized net gains of $86 million , $59 million , and $36 million , respectively. These gains related to miscellaneous investments sold during the year and have been reflected in Other loss, net in the Consolidated Statement of Operations. Investment Writedowns For the years ended December 31, 2016 , 2015 and 2014 , the Company incurred writedowns to reduce the carrying value of certain investments that experienced other-than-temporary impairments, as set forth below (millions): December 31, 2016 2015 2014 Equity-method investments $ 2 $ 2 $ 21 Cost-method investments 11 6 8 Available-for-sale securities — 19 6 Total $ 13 $ 27 $ 35 These amounts have been reflected in Other loss, net in the Consolidated Statement of Operations. While Time Warner has recognized all declines that are believed to be other-than-temporary as of December 31, 2016 , it is reasonably possible that individual investments in the Company’s portfolio may experience other-than-temporary declines in value in the future if the underlying investees experience adverse changes in their financial condition or poor operating results or if there is a significant decline in the market value of a debt or equity security held by the Company in relation to its cost basis.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS A fair value measurement is determined based on the assumptions that a market participant would use in pricing an asset or liability. A three-tiered hierarchy draws distinctions between market participant assumptions based on (i) observable inputs such as quoted prices in active markets (Level 1), (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2) and (iii) unobservable inputs that require the Company to use present value and other valuation techniques in the determination of fair value (Level 3). The following table presents information about assets and liabilities required to be carried at fair value on a recurring basis as of December 31, 2016 and December 31, 2015 , respectively (millions): December 31, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Trading securities: Diversified equity securities (a) $ 163 $ — $ — $ 163 $ 179 $ — $ — $ 179 Available-for-sale securities: Equity securities 17 — — 17 15 — — 15 Debt securities — 37 — 37 — 70 — 70 Derivatives: Foreign exchange contracts — 153 — 153 — 79 — 79 Other — — 161 161 — — 180 180 Liabilities: Derivatives: Foreign exchange contracts — (9 ) — (9 ) — (2 ) — (2 ) Other — — — — — — (7 ) (7 ) Total $ 180 $ 181 $ 161 $ 522 $ 194 $ 147 $ 173 $ 514 _________________________ (a) Consists of investments related to deferred compensation. The Company primarily applies the market approach for valuing recurring fair value measurements. As of December 31, 2016 and 2015 , assets valued using significant unobservable inputs (Level 3) primarily related to warrants to purchase shares of Class A common stock of CME valued at $159 million and $179 million , respectively. The Company estimates the fair value of these warrants using a Monte Carlo Simulation model. Significant unobservable inputs used in the fair value measurement at December 31, 2016 are an expected term of 0.82 years and an expected volatility of approximately 54% . As of December 31, 2016 and 2015 , the other Level 3 assets consisted of equity instruments held by employees of a former subsidiary of the Company. As of December 31, 2015, Level 3 liabilities consisted of liabilities for contingent consideration and options to redeem securities. The following table reconciles the beginning and ending balances of net derivative assets and liabilities classified as Level 3 and identifies the total gains (losses) the Company recognized during the year ended December 31, 2016 and 2015 on such assets and liabilities that were included in the Consolidated Balance Sheet as of December 31, 2016 and 2015 (millions): December 31, 2016 2015 Balance as of the beginning of the period $ 173 $ 241 Total gains (losses), net: Included in operating income 2 (1 ) Included in other loss, net (19 ) (65 ) Included in other comprehensive income (loss) — — Purchases — — Settlements 5 (2 ) Issuances — — Transfers in and/or out of Level 3 — — Balance as of the end of the period $ 161 $ 173 Net loss for the period included in net income related to assets and liabilities still held as of the end of the period $ (19 ) $ (66 ) Other Financial Instruments The Company’s other financial instruments, including debt, are not required to be carried at fair value. Based on the interest rates prevailing at December 31, 2016 , the fair value of Time Warner’s public debt exceeded its carrying value by approximately $2.238 billion and, based on interest rates prevailing at December 31, 2015 , the fair value of Time Warner’s public debt exceeded its carrying value by approximately $2.490 billion . The fair value of Time Warner’s public debt is considered a Level 2 measurement as it is based on observable market inputs such as current interest rates and, where available, actual sales transactions. Unrealized gains or losses on debt do not result in the realization or expenditure of cash and generally are not recognized in the consolidated financial statements unless the debt is retired prior to its maturity. See Note 9 for a discussion of the Company’s debt tender offers. Information as of December 31, 2016 about the Company’s investments in CME that are not required to be carried at fair value on a recurring basis is as follows (millions): Carrying Value Fair Value Fair Value Hierarchy Class A common stock (a) $ — $ 185 Level 1 Series B convertible redeemable preferred shares — 268 Level 2 _________________________ (a) Includes 1 share of Series A convertible preferred stock. The fair values of the Company’s investments in CME’s Class A common stock (including Series A convertible preferred stock) and Series B convertible redeemable preferred shares are primarily determined by reference to the December 31, 2016 closing price of CME’s common stock. The carrying value for the majority of the Company’s other financial instruments approximates fair value due to the short-term nature of the financial instruments or because the financial instruments are of a longer-term nature and are recorded on a discounted basis. Non-Financial Instruments The majority of the Company’s non-financial instruments, which include goodwill, intangible assets, inventories and property, plant and equipment, are not required to be carried at fair value on a recurring basis. However, if certain triggering events occur (or at least annually for goodwill and indefinite-lived intangible assets), a non-financial instrument is required to be evaluated for impairment. If the Company determines that the non-financial instrument is impaired, the Company would be required to write down the non-financial instrument to its fair value. During the year ended December 31, 2016 , the Company performed an impairment review of a broadcast license at an international subsidiary of Turner. As a result, the Company recorded a noncash impairment of $25 million to write down the value of the asset to $10 million . During the year ended December 31, 2015 the Company performed an impairment review of certain intangible assets at an international subsidiary of Turner. As a result, the Company recorded a noncash impairment of $1 million to completely write off the value of these assets. The resulting fair value measurements were considered to be Level 3 measurements and were determined using a DCF methodology with assumptions for cash flows associated with the use and eventual disposition of the assets. During the years ended December 31, 2016 and December 31, 2015 , the Company also performed fair value measurements related to certain theatrical films and television programs. In determining the fair value of its theatrical films, the Company employs a DCF methodology that includes cash flow estimates of a film’s ultimate revenue and costs as well as a discount rate. The discount rate utilized in the DCF analysis is based on the weighted average cost of capital of the respective business (e.g., Warner Bros.) plus a risk premium representing the risk associated with producing a particular theatrical film. The fair value of any theatrical films and television programs that management plans to abandon is zero . Because the primary determination of fair value is made using a DCF model, the resulting fair value is considered a Level 3 measurement. The following table presents certain theatrical film and television production costs, which were recorded as inventory in the Consolidated Balance Sheet, that were written down to fair value (millions): Carrying value before write down Carrying value after write down Fair value measurements made during the year ended December 31,: 2016 $ 285 $ 128 2015 419 215

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Time Warner uses derivative instruments, primarily forward contracts, to manage the risk associated with the volatility of future cash flows denominated in foreign currencies and changes in fair value resulting from changes in foreign currency exchange rates. The principal currencies being hedged include the British Pound, Euro, Australian Dollar and Canadian Dollar. Time Warner uses foreign exchange contracts that generally have maturities of three to 18 months to hedge various foreign exchange exposures, including the following: (i) variability in foreign-currency-denominated cash flows, such as the hedges of unremitted or forecasted royalty and license fees owed to Time Warner’s domestic companies for the sale or anticipated sale of U.S. copyrighted products abroad or cash flows for certain film production costs denominated in a foreign currency (i.e., cash flow hedges), and (ii) currency risk associated with foreign-currency-denominated operating assets and liabilities (i.e., fair value hedges). The Company also enters into derivative contracts that economically hedge certain of its foreign currency risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. These economic hedges are used primarily to offset the change in certain foreign-currency-denominated intercompany debt due to changes in the underlying foreign exchange rates. The translation of revenues and expenses denominated in the functional currency of a foreign subsidiary may result in fluctuations in the U.S. Dollar-equivalent value of such revenues and expenses as compared to prior periods. Such transactions are not eligible for qualifying hedge accounting treatment, and the Company does not economically hedge this exposure. Net gains and losses from hedging activities recognized in the Consolidated Statement of Operations were as follows (millions): Year Ended December 31, 2016 2015 2014 Gains (losses) recognized in: Cost of revenues $ 81 $ 127 $ 54 Selling, general and administrative 14 21 5 Other loss, net (34 ) (26 ) — Amounts included in Other loss, net include the impact of forward points and option premiums, which are excluded from the assessment of hedge effectiveness. Other amounts included in Other loss, net relate to hedge of foreign-currency-denominated debt and hedge ineffectiveness, which are not material. The Company monitors its positions with, and the credit quality of, the financial institutions that are party to its financial transactions and has entered into collateral agreements with these counterparties to further protect the Company in the event of deterioration of the credit quality of such counterparties on outstanding transactions. Additionally, netting provisions are included in agreements in situations where the Company executes multiple contracts with the same counterparty. For such foreign exchange contracts, the Company offsets the fair values of the amounts owed to or due from the same counterparty and classifies the net amount as a net asset or net liability within Prepaid expenses and other current assets or Accounts payable and accrued liabilities, respectively, in the Consolidated Balance Sheet. The following is a summary of amounts recorded in the Consolidated Balance Sheet pertaining to Time Warner’s use of foreign currency derivatives at December 31, 2016 and December 31, 2015 (millions): December 31, 2016 (a) 2015 (b) Prepaid expenses and other current assets $ 153 $ 79 Accounts payable and accrued liabilities (9 ) (2 ) _________________________ (a) Includes $297 million ( $272 million of qualifying hedges and $25 million of economic hedges) and $153 million ( $141 million of qualifying hedges and $12 million of economic hedges) of foreign exchange derivative contracts in asset and liability positions, respectively. (b) Includes $198 million ( $194 million of qualifying hedges and $4 million of economic hedges) and $121 million ( $116 million of qualifying hedges and $5 million of economic hedges) of foreign exchange derivative contracts in asset and liability positions, respectively. At December 31, 2016 and December 31, 2015 , $46 million and $29 million of gains, respectively, related to cash flow hedges are recorded in Accumulated other comprehensive loss, net and are expected to be recognized in earnings at the same time the hedged items affect earnings. Included in Accumulated other comprehensive loss, net at December 31, 2016 and December 31, 2015 are net losses of $3 million and $9 million , respectively, related to hedges of cash flows associated with films that are not expected to be released within the next twelve months. At December 31, 2016 , the carrying amount of the Company’s €700 million aggregate principal amount of debt due 2023 is designated as a hedge of the variability in the Company’s Euro-denominated net investments. The gain or loss on the debt that is designated as, and is effective as, an economic hedge of the net investment in a foreign operation is recorded as a currency translation adjustment within Accumulated other comprehensive loss, net in the Consolidated Balance Sheet. For the years ended December 31, 2016 and 2015 , such amounts totaled $39 million of gains and $1 million of gains , respectively. See Note 9 for more information.

Debt Disclosure [Abstract]
LONG TERM DEBT AND OTHER FINANCING ARRANGEMENTS	LONG-TERM DEBT AND OTHER FINANCING ARRANGEMENTS The Company’s long-term debt and other financing arrangements consist of revolving bank credit facilities, a commercial paper program, fixed-rate public debt and other obligations. The principal amounts of long-term debt adjusted for premiums, discounts and issuance costs consist of (millions): December 31, 2016 2015 Fixed-rate public debt $ 22,715 $ 23,572 Revolving credit facilities and commercial paper program 1,394 — Other obligations 230 220 Subtotal 24,339 23,792 Debt due within one year (1,947 ) (198 ) Total long-term debt $ 22,392 $ 23,594 The Company’s unused committed capacity as of December 31, 2016 was $5.162 billion , including $1.539 billion of Cash and equivalents. At December 31, 2016 , there were no borrowings outstanding under the Revolving Credit Facilities, as defined below, and $1.394 billion of commercial paper was outstanding under the commercial paper program. The Revolving Credit Facilities, commercial paper program and public debt of the Company rank pari passu with the senior debt of the respective obligors thereon. The weighted-average interest rate on Time Warner’s total debt was 4.97% and 5.65% at December 31, 2016 and 2015 , respectively. Revolving Credit Facilities and Commercial Paper Program Revolving Credit Facilities On December 16, 2016, Time Warner amended its $5.0 billion of senior unsecured credit facilities (the “Revolving Credit Facilities”), which consist of two $2.5 billion revolving credit facilities, to extend the maturity dates of both facilities from December 18, 2020 to December 18, 2021 and eliminate the swingline loan subfacility included in one of its facilities. The permitted borrowers under the Revolving Credit Facilities are Time Warner and Time Warner International Finance Limited (“TWIFL” and, together with Time Warner, the “Borrowers”). The interest rate on borrowings and facility fees under the Revolving Credit Facilities are the same for both revolving credit facilities and are based on the credit rating for Time Warner’s senior unsecured long-term debt. Based on the credit rating as of December 31, 2016 , the interest rate on borrowings under the Revolving Credit Facilities would be LIBOR plus 1.10% per annum and the facility fee was 0.15% per annum. The Revolving Credit Facilities provide same-day funding and multi-currency capability, and a portion of the commitment, not to exceed $500 million at any time, may be used for the issuance of letters of credit. The covenants in the Revolving Credit Facilities include a maximum consolidated leverage ratio covenant of 4.5 times the consolidated EBITDA, as defined in the Revolving Credit Facilities, of Time Warner, but exclude any credit ratings-based defaults or covenants or any ongoing covenant or representations specifically relating to a material adverse change in Time Warner’s financial condition or results of operations. The terms and related financial metrics associated with the leverage ratio are defined in the Revolving Credit Facilities. At December 31, 2016 , the Company was in compliance with the leverage covenant, with a consolidated leverage ratio of approximately 2.85 times . Borrowings under the Revolving Credit Facilities may be used for general corporate purposes, and unused credit is available to support borrowings by Time Warner under its commercial paper program. The Revolving Credit Facilities also contain certain events of default customary for credit facilities of this type (with customary grace periods, as applicable). The Borrowers may from time to time, so long as no default or event of default has occurred and is continuing, increase the commitments under either or both of the Revolving Credit Facilities by up to $500 million per facility by adding new commitments or increasing the commitments of willing lenders. The obligations of each of the Borrowers under the Revolving Credit Facilities are directly or indirectly guaranteed, on an unsecured basis, by Historic TW Inc. (“Historic TW”), Home Box Office and Turner. The obligations of TWIFL under the Revolving Credit Facilities are also guaranteed by Time Warner. Commercial Paper Program The Company has a commercial paper program, which was established on February 16, 2011 on a private placement basis, under which Time Warner may issue unsecured commercial paper notes up to a maximum aggregate amount not to exceed the unused committed capacity under the $5.0 billion Revolving Credit Facilities, which support the commercial paper program. Unsecured commercial paper notes issued by the Company typically mature in less than 90 days. Proceeds from the commercial paper program may be used for general corporate purposes. The obligations of the Company under the commercial paper program are directly or indirectly guaranteed, on an unsecured basis, by Historic TW, Home Box Office and Turner. As of December 31, 2016, the Company had $1.394 billion of commercial paper outstanding, which is supported by the Revolving Credit Facilities. Public Debt Time Warner and one of its subsidiaries have various public debt issuances outstanding. At issuance, the maturities of these outstanding series of debt ranged from five to 40 years and the interest rates on debt with fixed interest rates ranged from 1.95% to 9.15% . At December 31, 2016 and 2015 , the weighted average interest rate on the Company’s outstanding fixed-rate public debt was 5.23% and 5.67% , respectively. At December 31, 2016 , the Company’s fixed-rate public debt had maturities ranging from 2017 to 2045. Debt Offerings On May 10, 2016, Time Warner issued $800 million aggregate principal amount of 2.95% Notes due 2026 under a shelf registration statement. The net proceeds to the Company from the debt offering were $785 million , after deducting underwriting discounts and offering expenses. On December 8, 2016, Time Warner issued $1.5 billion aggregate principal amount of 3.80% Notes due 2027 under a shelf registration statement. The net proceeds to the Company from the debt offering were $1.487 billion , after deducting underwriting discounts and offering expenses. All of the notes issued are guaranteed, on an unsecured basis, by Historic TW. In addition, Turner and Home Box Office guarantee, on an unsecured basis, Historic TW’s guarantee of the notes. Debt Tender Offers On December 14, 2016, Time Warner purchased through cash tender offers $3.0 billion aggregate principal amount of its outstanding debt from the following series: 7.700% Debentures due 2032, 7.625% Debentures due 2031, 6.500% Debentures due 2036 and 6.625% Debentures due 2029, each of which continues to have amounts outstanding. The premiums paid and costs incurred in connection with this purchase were $1.008 billion for the year ended December 31, 2016 and were recorded in Other loss, net in the Consolidated Statement of Operations. Maturities of Public Debt The Company’s public debt matures as follows (millions): 2017 2018 2019 2020 2021 Thereafter Debt $ 500 $ 600 $ 650 $ 1,400 $ 2,000 $ 17,767 Covenants and Credit Rating Triggers Each of the credit agreements for the Revolving Credit Facilities (the “Credit Agreement”) and the Company’s public debt indentures contain customary covenants. A breach of the covenants in the Credit Agreement that continues beyond any grace period constitutes a default, which can limit the Company’s ability to borrow and can give rise to a right of the lenders to terminate the Revolving Credit Facilities and/or require immediate payment of any outstanding debt. A breach of the covenants in the public debt indentures beyond any grace period constitutes a default, which can require immediate payment of the outstanding debt. There are no credit ratings-based defaults or covenants in the Credit Agreement or public debt indentures. The interest rate on borrowings under the Revolving Credit Facilities and the facility fee are based in part on the Company’s credit ratings. Therefore, if the Company’s credit ratings are lowered, the cost of maintaining the Revolving Credit Facilities and the cost of borrowing increase and, conversely, if the ratings improve, such costs decrease. As of December 31, 2016 , the Company’s investment grade debt ratings were as follows: Fitch BBB+, Moody’s Baa2, and S&P BBB. As of December 31, 2016 , the Company was in compliance with all covenants in the Credit Agreement and its public debt indentures. The Company does not anticipate that it will have any difficulty in the foreseeable future complying with the covenants in its Credit Agreement or public debt indentures. Other Obligations Other long-term debt obligations consist of capital lease and other obligations, including committed financings by subsidiaries under local bank credit agreements. At December 31, 2016 and 2015 , the weighted average interest rate for other long-term debt obligations was 3.18% and 3.32% , respectively. Other long-term debt obligations of $125 million mature in 2018. Capital Leases The Company has entered into various leases primarily related to network equipment that qualify as capital lease obligations. As a result, the present value of the remaining future minimum lease payments is recorded as a capitalized lease asset and related capital lease obligation in the Consolidated Balance Sheet. Assets recorded under capital lease obligations totaled $118 million and $125 million as of December 31, 2016 and 2015 , respectively. Related accumulated amortization totaled $64 million and $81 million as of December 31, 2016 and 2015 , respectively. Future minimum capital lease payments at December 31, 2016 are as follows (millions): 2017 $ 16 2018 16 2019 14 2020 11 2021 5 Thereafter 6 Total 68 Amount representing interest (7 ) Present value of minimum lease payments 61 Current portion (14 ) Total long-term portion $ 47

The tax attribute carryforwards consist of $97 million of tax credits, $74 million of capital losses and $264 million of net operating losses that expire in varying amounts from 2017 through 2036. If, in the future, the Company believes that it is more likely than not that these deferred tax benefits will be realized, the valuation allowances will be recognized in the Consolidated Statement of Operations. U.S. income and foreign withholding taxes have not been recorded on permanently reinvested earnings of certain foreign subsidiaries aggregating approximately $1.6 billion at December 31, 2016 . Determination of the amount of unrecognized deferred U.S. income tax liability with respect to such earnings is not practicable. For accounting purposes, the Company records equity-based compensation expense and a related deferred tax asset for the future tax deductions it may receive. For income tax purposes, the Company receives a tax deduction equal to the stock price on the date that an RSU (or PSU) vests or the excess of the stock price over the exercise price of an option upon exercise. The deferred tax asset consists of amounts relating to individual unvested and/or unexercised equity-based compensation awards; accordingly, deferred tax assets related to certain equity awards may currently be in excess of the tax benefit ultimately received. The applicable accounting rules require that the deferred tax asset related to an equity-based compensation award be reduced only at the time the award vests (in the case of an RSU or PSU), is exercised (in the case of a stock option) or otherwise expires or is canceled. This reduction is recorded as an adjustment to Additional paid-in capital (“APIC”), to the extent that the realization of excess tax deductions on prior equity-based compensation awards were recorded directly to APIC. The cumulative amount of such excess tax deductions is referred to as the Company’s “APIC Pool.” Any shortfall balance recognized in excess of the Company’s APIC Pool is charged to Income tax provision in the Consolidated Statement of Operations. The Company’s APIC Pool was sufficient to absorb any shortfalls such that no shortfalls were charged to the Income tax provision during the years ended December 31, 2016 , 2015 and 2014 . See Note 1 for a discussion of accounting guidance for share-based payments that became effective January 1, 2017. Accounting for Uncertainty in Income Taxes The Company recognizes income tax benefits for tax positions determined more likely than not to be sustained upon examination, based on the technical merits of the positions. Changes in the Company’s uncertain income tax positions, excluding the related accrual for interest and penalties, from January 1 through December 31 are set forth below (millions): Year Ended December 31, 2016 2015 2014 Beginning balance $ 1,330 $ 1,327 $ 2,169 Additions for prior year tax positions 154 61 87 Additions for current year tax positions 81 62 69 Reductions for prior year tax positions (203 ) (75 ) (968 ) Settlements (29 ) (40 ) (8 ) Lapses in statute of limitations (8 ) (5 ) (22 ) Ending balance $ 1,325 $ 1,330 $ 1,327 Should the Company’s position with respect to these uncertain tax positions be upheld, the significant majority of the effect would be recorded in the Consolidated Statement of Operations as part of the Income tax provision. During the year ended December 31, 2016 , the Company recorded an increase to interest reserves in the Consolidated Statement of Operations of approximately $58 million and made interest payments in connection with settlements reached during 2016 of approximately $17 million . During the year ended December 31, 2015 , the Company recorded an increase to interest reserves in the Consolidated Statement of Operations of approximately $55 million and made interest payments in connection with settlements reached during 2015 of approximately $19 million . The amount accrued for interest and penalties as of December 31, 2016 and 2015 was $423 million and $382 million , respectively. The Company’s policy is to recognize interest and penalties accrued on uncertain tax positions as part of income tax expense. In the Company’s judgment, uncertainties related to certain tax matters are reasonably possible of being resolved during the next twelve months. The effect of the resolutions of these matters, a portion of which could vary based on the final terms and timing of actual settlements with taxing authorities, is estimated to be a reduction of recorded unrecognized tax benefits ranging from $0 to $270 million , which would lower the Company’s effective tax rate. The Company does not otherwise currently anticipate that its reserves related to uncertain income tax positions as of December 31, 2016 will significantly increase or decrease during the twelve-month period ended December 31, 2017 ; however, various events could cause the Company’s current expectations to change in the future. During the year ended December 31, 2014, the Company recognized a tax benefit of $687 million primarily related to the reversal of certain tax reserves, including related interest accruals, in connection with a Federal tax settlement on the examination of the Company’s 2005–2007 tax returns. Certain matters involving the Company’s capital loss carryforward and research and development tax credits were not resolved as part of the settlement and, accordingly, the Company is pursuing resolution of such matters through the Internal Revenue Service’s (“IRS”) administrative appeals process. The Company and its subsidiaries file income tax returns in the U.S. and various state and local and foreign jurisdictions. The IRS is currently conducting an examination of the Company’s U.S. income tax returns for the 2008 through 2014 period. The Company filed a petition with the United States Tax Court on a matter relating to the appropriate tax characterization of stock warrants received from Google Inc. in 2002. In December 2014, the Company reached a preliminary agreement with the IRS, subject to agreement regarding certain necessary computations and the preparation and execution of definitive documentation. In February 2016, the parties reached a final agreement to resolve this matter. As of December 31, 2016 , the tax years that remain subject to examination by significant jurisdiction are as follows: U.S. federal 2005 through 2016 California 2010 through 2016 New York State 2012 through 2016 New York City 2012 through 2016

EQUITY-BASED COMPENSATION	EQUITY-BASED COMPENSATION Equity Plans The Company has one active equity plan, the Time Warner Inc. 2013 Stock Incentive Plan (the “2013 Stock Incentive Plan”), which was approved by the Company’s stockholders on May 23, 2013. Under the 2013 Stock Incentive Plan, the Company is authorized to grant equity awards to employees and non-employee directors covering an aggregate of approximately 36 million shares of the Company’s common stock. Stock options and RSUs have been granted to employees and non-employee directors of the Company. Generally, stock options are granted with exercise prices equal to the fair market value on the date of grant, vest in four equal annual installments, and expire ten years from the date of grant. RSUs granted under the 2013 Stock Incentive Plan generally vest in four equal annual installments, while RSUs granted under the Company’s prior stock incentive plans generally vest 50% on each of the third and fourth anniversaries of the date of grant. The Company also has a PSU program for executive officers who are awarded a target number of PSUs that represent the contingent (unfunded) right to receive shares of Company common stock at the end of a three -year performance period based on the performance level achieved by the Company. Stock options and RSUs generally provide for accelerated vesting upon an election to retire after reaching a specified age and years of service, as well as in certain additional circumstances for non-employee directors. In connection with entering into the Merger Agreement, the Company has granted special retention restricted stock units (“Special Retention RSUs”) to certain employees of Time Warner and its divisions, including all executive officers of Time Warner. Half of the Special Retention RSUs will vest 25% per year on each of the first four anniversaries of February 15, 2017, and the remaining half will vest 25% per year on each of the first four anniversaries of February 15, 2018. Pursuant to the Special Retention RSU agreements, vesting as a result of retirement is not permitted unless the employee retires after the merger has closed. In addition, the awards do not accelerate automatically following the closing of the merger. Instead, the employee must remain employed following the closing, and the awards will vest only upon the scheduled vesting date or upon termination of employment under certain circumstances, such as termination without cause, for good reason or due to retirement. Holders of RSUs are generally entitled to receive cash dividend equivalents based on the regular quarterly cash dividends declared and paid by the Company during the period that the RSUs are outstanding. Beginning with RSU grants made in 2013, the dividend equivalent payment for holders of RSUs subject to a performance condition is made in cash following the satisfaction of the performance condition. Holders of PSUs also are entitled to receive dividend equivalents based on the regular quarterly cash dividends declared and paid by the Company during the period that the PSUs are outstanding. The dividend equivalent payment is made in cash following the vesting of the PSUs (generally following the end of the applicable performance period) and is based on the number of shares that vest and are paid out. Holders of stock options do not receive dividends or dividend equivalent payments. Upon the (i) exercise of a stock option, (ii) vesting of an RSU or (iii) vesting of a PSU, shares of Time Warner common stock may be issued either from authorized but unissued shares or from treasury stock. In connection with the Time Separation and in accordance with existing antidilution provisions in the Company’s equity plans, the number of stock options, RSUs and target PSUs outstanding at the Distribution Date and the exercise prices of such stock options were prospectively adjusted to maintain the value of those awards subsequent to the Time Separation (the “Adjustment”). The changes in the number of shares subject to outstanding equity awards and the exercise prices were determined by comparing the value of such awards immediately prior to the Time Separation to the value of such awards immediately after the Time Separation. Accordingly, the number of shares subject to each equity award outstanding as of the Distribution Date was increased by multiplying such number of shares by a factor of approximately 1.04 , while the per share exercise price of each stock option was decreased by dividing such exercise price by a factor of approximately 1.04 . The adjustments resulted in an increase of approximately 2 million shares subject to outstanding equity awards following the Time Separation. The adjustments to the outstanding equity awards did not result in any additional compensation expense. Other information pertaining to each category of equity-based compensation appears below. Stock Options The table below summarizes the weighted-average assumptions used to value stock options at their grant date and the weighted-average grant date fair value per share: Year Ended December 31, 2016 2015 2014 Expected volatility 26.0 % 25.0 % 26.6 % Expected term to exercise from grant date 6.20 years 5.80 years 5.85 years Risk-free rate 1.5 % 1.8 % 1.9 % Expected dividend yield 2.6 % 1.7 % 1.7 % Weighted average grant date fair value per option $ 12.26 $ 18.16 $ 16.94 The following table summarizes information about stock options outstanding as of December 31, 2016 : Number of Options Weighted- Average Exercise Price Weighted- Average Remaining Contractual Life Aggregate Intrinsic Value (thousands) (in years) (thousands) Outstanding as of December 31, 2015 27,742 $ 42.98 Granted 2,263 62.45 Exercised (5,317 ) 32.38 Forfeited or expired (121 ) 41.81 Outstanding as of December 31, 2016 24,567 47.07 4.87 $ 1,216,194 Exercisable as of December 31, 2016 18,042 37.63 3.64 $ 1,063,245 As of December 31, 2016 , the number, weighted-average exercise price, aggregate intrinsic value and weighted-average remaining contractual term of the aggregate Time Warner stock options that either had vested or are expected to vest approximate the corresponding amounts for options outstanding.

BENEFIT PLANS	BENEFIT PLANS Time Warner Pension Plan Amendment On August 1, 2016, the Time Warner Pension Plan was amended to provide a window for a one-time lump sum payment for eligible vested participants who (i) had terminated employment as of May 31, 2016, (ii) had not yet commenced payment of their benefits as of May 31, 2016, (iii) are not otherwise eligible for an immediate lump sum payment of their benefits and (iv) have benefits with a present value of less than $50,000 . Eligible participants had the opportunity to elect, during the period beginning on August 16, 2016 and ending on October 7, 2016, to receive their benefits in the form of an immediate lump sum payment. Certain annuity options were also available. Payments to those eligible participants who elected to receive their benefit under the window program were made or commenced in December 2016. Defined Benefit Pension Plans A summary of activity for substantially all of Time Warner’s domestic and international defined benefit pension plans is as follows: Benefit Obligation (millions) December 31, 2016 2015 Change in benefit obligation: Projected benefit obligation, beginning of year $ 3,439 $ 3,694 Service cost 4 4 Interest cost 145 147 Actuarial gain (169 ) (204 ) Benefits paid (274 ) (177 ) Curtailments — (1 ) Remeasurement 407 — Foreign currency exchange rates (87 ) (24 ) Projected benefit obligation, end of year $ 3,465 $ 3,439 Accumulated benefit obligation, end of year $ 3,433 $ 3,405 Plan Assets (millions) December 31, 2016 2015 Change in plan assets: Fair value of plan assets, beginning of year $ 2,698 $ 2,932 Actual return on plan assets 345 (84 ) Employer contributions 74 49 Benefits paid (274 ) (177 ) Foreign currency exchange rates (105 ) (22 ) Fair value of plan assets, end of year $ 2,738 $ 2,698 As of December 31, 2016 and December 31, 2015 , the funded status for substantially all of Time Warner’s domestic and international defined benefit pension plans recognized in the Consolidated Balance Sheet reflected a net liability position of $727 million and $741 million , respectively, primarily consisting of noncurrent liabilities of $837 million and $798 million , respectively. As of December 31, 2016 and December 31, 2015 , amounts included in Accumulated other comprehensive loss, net were $1.335 billion and $1.402 billion , respectively, primarily consisting of net actuarial losses. Certain defined benefit pension plans have projected benefit obligations and accumulated benefit obligations in excess of their plan assets. These plans are primarily unfunded. As of December 31, 2016 and December 31, 2015 , the projected benefit obligations for unfunded plans were $414 million and $417 million , respectively, and the accumulated benefit obligations for unfunded plans were $407 million and $410 million , respectively. In addition, as of December 31, 2016 , the projected benefit obligation and accumulated benefit obligation for certain funded plans exceeded the fair value of their assets by $457 million and $455 million , respectively.

These amounts have been reflected in Other loss, net in the Consolidated Statement of Operations. In addition, net periodic benefit costs for the year ended December 31, 2016 also excludes $46 million of pension settlement charges related to businesses the Company previously disposed of. These amounts have been reflected in Discontinued Operations, net of tax, in the Consolidated Statement of Operations. Assumptions Weighted-average assumptions used to determine benefit obligations and net periodic benefit costs for the years ended December 31: Benefit Obligations Net Periodic Benefit Costs 2016 2015 2014 2016 2015 2014 Discount rate 3.96 % 4.59 % 4.10 % 4.30 % 4.10 % 4.89 % Rate of compensation increase 5.62 % 5.45 % 5.34 % 5.45 % 5.35 % 5.59 % Expected long-term return on plan assets n/a n/a n/a 5.91 % 5.84 % 6.01 % The discount rates were determined by matching the plan’s liability cash flows to rates derived from high-quality corporate bonds available at the measurement date. In developing the expected long-term rate of return on plan assets, the Company considered long-term historical rates of return, the Company’s plan asset allocations as well as the opinions and outlooks of investment professionals and consulting firms. Fair Value of Plan Assets The following table sets forth by level, within the fair value hierarchy described in Note 6, the assets and liabilities held by the Company’s defined benefit pension plans, including those assets related to The CW sub-plan, which were approximately $20 million and $18 million , respectively, as of December 31, 2016 and December 31, 2015 (millions): December 31, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Cash and cash equivalents (a) $ 142 $ — $ — $ 142 $ 81 $ — $ — $ 81 Insurance contracts — 15 — 15 — 15 — 15 Common stocks 165 — — 165 148 — — 148 Fixed income securities: U.S. government and agency securities (a) 200 62 — 262 191 67 — 258 Non-U.S. government and agency securities 250 — — 250 106 — — 106 Other fixed income securities (b) — 952 — 952 — 1,147 — 1,147 Other investments (c) 156 68 — 224 138 20 — 158 Liabilities: Derivatives — (19 ) — (19 ) — (41 ) — (41 ) Total (d) $ 913 $ 1,078 $ — $ 1,991 $ 664 $ 1,208 $ — $ 1,872 _________________________ (a) As of December 31, 2016 , cash and cash equivalents include $17 million of cash collateral for securities on loan, and U.S. government and agency securities include $66 million of securities collateral for securities on loan. As of December 31, 2015, cash and cash equivalents include $10 million of cash collateral for securities on loan, and U.S. government and agency securities include $59 million of securities collateral for securities on loan. (b) Other fixed income securities primarily include investment grade corporate bonds. (c) Other investments primarily include derivative contracts, exchange-traded funds and mutual funds. (d) At December 31, 2016 and December 31, 2015 , total assets include $81 million and $67 million , respectively, of securities on loan. Certain investments that are measured at fair value using the net asset value ("NAV") per share as a practical expedient have not been categorized in the fair value table above and are as follows (millions): December 31, Asset Category 2016 2015 Pooled investments (e) 231 357 Commingled trust funds 610 469 Other investments (f) 56 67 Total $ 897 $ 893 (e) Pooled investments primarily consist of interests in unitized investment pools which consist of equity and fixed income securities and investments in hedge funds.

The Company’s defined benefit pension plans’ investment policy is to minimize the volatility of the plans’ funded status and to achieve and maintain fully funded status in order to pay current and future participant benefits from plan assets. The Company periodically reviews asset allocation policies consistent with its investment policy. In addition, the Company continuously monitors the performance of its pension assets, the performance of its investment advisers, sub-advisers and asset managers thereof, and makes adjustments and changes as required. The Company does not manage any pension assets internally. The investment guidelines set by the Company for the investment advisers, sub-advisers and asset managers permit the use of index funds, derivative contracts and other hedging strategies as components of portfolio management strategies. Under the Company’s investment policy, the asset allocation target for the funded domestic defined benefit pension plan is approximately 40% equity investments and 60% fixed income investments. As and when funded status and market conditions permit, the Company intends to move 5% of the fixed income investments to equity investments comprised of growth assets for each 5% decline in the funding level until the fixed income investment allocation reaches a minimum of 50% of the plan’s assets. In addition, should funding improve over time, 5% of the growth assets would be moved to fixed income investments for every 5% increase in funding level toward a target of approximately 20% equity investments and 80% fixed income investments to further minimize funded status volatility. The plan’s growth assets will be further diversified over time to include real estate funds that invest in high quality properties with a small degree of leverage. Target asset allocations for the international defined benefit pension plans as of December 31, 2016 are approximately 30% equity investments, 50% fixed income investments and 20% other investments. At both December 31, 2016 and December 31, 2015 , the defined benefit pension plans’ assets did not include any securities issued by Time Warner. Expected cash flows After considering the funded status of the Company’s defined benefit pension plans, movements in the discount rate, investment performance and related tax consequences, the Company may choose to make contributions to its pension plans in any given year. The Company made discretionary cash contributions totaling approximately $40 million to one of its funded international defined benefit pension plans during the year ended December 31, 2016 . For the Company’s unfunded plans, contributions will continue to be made to the extent benefits are paid. Information about the expected benefit payments for the Company’s defined benefit plans is as follows (millions): 2017 2018 2019 2020 2021 2022-2026 Expected benefit payments $ 171 $ 176 $ 174 $ 185 $ 186 $ 993 Defined Contribution Plans Time Warner has certain domestic and international defined contribution plans, including savings and profit sharing plans, for which the expense amounted to $149 million in 2016 , $153 million in 2015 and $160 million in 2014 . The Company’s contributions to the savings plans are primarily based on a percentage of the employees’ elected contributions and are subject to plan provisions. Other Postretirement Benefit Plans In July 2013, the Company discontinued subsidized medical benefits provided to all future retirees who were employed on December 31, 2013 and who would not have met the eligibility criteria by December 31, 2015 and effective January 1, 2014, post-65 retiree medical coverage was discontinued and eligible retirees were moved to coverage provided in the individual health insurance market. Time Warner also sponsors several unfunded domestic postretirement benefit plans covering certain retirees and their dependents. For substantially all of Time Warner’s domestic postretirement benefit plans, the unfunded benefit obligation as of December 31, 2016 and December 31, 2015 was $88 million and $93 million , respectively, and the amount recognized in Accumulated other comprehensive income, net was a gain of $19 million and $19 million , respectively. For the years ended December 31, 2016 , 2015 and 2014 , the net periodic benefit costs were $1 million , $2 million and $2 million , respectively. Multiemployer Benefit Plans The Company contributes to various multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover certain of its union-represented employees, primarily at the Warner Bros. segment. The risks of participating in these multiemployer pension plans are different from single-employer pension plans in that (i) contributions made by the Company to the multiemployer pension plans may be used to provide benefits to employees of other participating employers; (ii) if the Company chooses to stop participating in certain of these multiemployer pension plans, it may be required to pay those plans an amount based on the underfunded status of the plan, which is referred to as a withdrawal liability; and (iii) actions taken by a participating employer that lead to a deterioration of the financial health of a multiemployer pension plan may result in the unfunded obligations of the multiemployer pension plan being borne by its remaining participating employers. While no multiemployer pension plan contributed to by the Company is individually significant, the Pension Protection Act of 2006 zone status as of December 31, 2016 (i.e., for the multiemployer pension plan’s 2015 plan year) of all of the largest multiemployer pension plans in which the Company participates was green, which implies that such plans are funded at a level of 80 percent or greater. Total contributions made by the Company to multiemployer pension plans for the years ended December 31, 2016 , 2015 and 2014 were $128 million , $139 million and $124 million , respectively. Included in the amounts for 2015 and 2014 are contributions of less than $1 million in each year that Home Box Office made to the Radio, Television and Recording Arts Pension Fund (“RT&RA Plan”) under a collective bargaining agreement that expired in October 2015. In February 2016, Home Box Office completed the negotiation of a new collective bargaining agreement under which it is no longer be required to make contributions to the RT&RA Plan. As a result, Home Box Office has withdrawn from the RT&RA Plan and recorded a $9 million charge in Selling, general and administrative expenses during the year ended December 31, 2016 for its withdrawal liability. The Company also contributes to various other multiemployer benefit plans that provide health and welfare benefits to active and retired participants, primarily at the Warner Bros. segment. Total contributions made by the Company to these other multiemployer benefit plans for the years ended December 31, 2016 , 2015 and 2014 were $194 million , $220 million and $205 million , respectively.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Time Warner classifies its operations into three reportable segments: Turner : consisting principally of cable networks and digital media properties; Home Box Office : consisting principally of premium pay television and OTT services domestically and premium pay, basic tier television and OTT services internationally; and Warner Bros. : consisting principally of television, feature film, home video and videogame production and distribution. Time Warner’s reportable segments have been determined in accordance with its internal management structure and the financial information that is evaluated regularly by the Company’s chief operating decision maker. In the ordinary course of business, Time Warner’s reportable segments enter into transactions with one another. The most common types of intersegment transactions include the Warner Bros. segment generating revenues by licensing television and theatrical programming to the Turner and Home Box Office segments. While intersegment transactions are treated like third-party transactions to determine segment performance, the revenues (and corresponding expenses or assets recognized by the segment that is the counterparty to the transaction) are eliminated in consolidation and, therefore, do not affect consolidated results. Information as to the Revenues, intersegment revenues, depreciation of property, plant, and equipment, Amortization of intangible assets, Operating Income (Loss), Assets and Capital expenditures for each of Time Warner’s reportable segments is set forth below (millions): Year Ended December 31, 2016 2015 2014 Revenues Turner $ 11,364 $ 10,596 $ 10,396 Home Box Office 5,890 5,615 5,398 Warner Bros. 13,037 12,992 12,526 Intersegment eliminations (973 ) (1,085 ) (961 ) Total revenues $ 29,318 $ 28,118 $ 27,359 Year Ended December 31, 2016 2015 2014 Intersegment Revenues Turner $ 108 $ 105 $ 101 Home Box Office (9 ) 40 36 Warner Bros. 874 940 824 Total intersegment revenues $ 973 $ 1,085 $ 961 Year Ended December 31, 2016 2015 2014 Supplemental Revenue Data Subscription $ 11,014 $ 10,153 $ 9,945 Advertising 4,696 4,569 4,502 Content 12,935 12,771 12,350 Other 673 625 562 Total revenues $ 29,318 $ 28,118 $ 27,359 Year Ended December 31, 2016 2015 2014 Depreciation of Property, Plant and Equipment Turner $ (191 ) $ (193 ) $ (209 ) Home Box Office (74 ) (81 ) (77 ) Warner Bros.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments Time Warner has commitments under certain network programming, film licensing, creative talent, employment and other agreements aggregating $39.973 billion at December 31, 2016 . The Company also has commitments for office space, studio facilities and operating equipment. Time Warner’s net rent expense was $324 million in 2016 , $333 million in 2015 and $358 million in 2014 . Included in such amounts was sublease income of $10 million for 2016 , $15 million for 2015 and $33 million for 2014 . The commitments under certain programming, film licensing, talent and other agreements (“Programming and Other”) and minimum rental commitments under noncancelable long-term operating leases (“Operating Leases”) payable during the next five years and thereafter are as follows (millions): Programming and Other Operating Leases 2017 $ 6,577 $ 310 2018 4,713 285 2019 3,918 146 2020 3,674 91 2021 3,458 63 Thereafter 17,633 259 Total $ 39,973 $ 1,154 Additionally, as of December 31, 2016 , the Company has future sublease income arrangements of $16 million , which are not included in Operating Leases in the table above. Contingent Commitments The Company also has certain contractual arrangements that would require it to make payments or provide funding if certain circumstances occur (“contingent commitments”). Contingent commitments principally include amounts that could be paid in connection with guarantees provided by the Company and post-production term advance obligations on certain co-financing arrangements. The following table summarizes the Company’s contingent commitments at December 31, 2016 . For post-production term advances where payment obligations are outside the Company’s control, the timing of amounts presented in the table represents the earliest period in which the payment could be requested. For other contingent commitments, the timing of amounts presented in the table represents when the maximum contingent commitment will expire, but does not mean that the Company expects to incur an obligation to make any payments within that time period. In addition, amounts presented do not reflect the effects of any indemnification rights the Company might possess (millions). Nature of Contingent Commitments Total 2017 2018-2019 2020-2021 Thereafter Guarantees $ 2,113 $ 136 $ 614 $ 612 $ 751 Post-production term advance obligations and other contingent commitments 1,021 46 430 545 — Total contingent commitments $ 3,134 $ 182 $ 1,044 $ 1,157 $ 751 The following is a description of the Company’s contingent commitments at December 31, 2016 : • Guarantees consist of the guarantee of certain debt issued by CME, an equity method investee, the Six Flags arrangement described below, and guarantees the Company has provided on operating lease commitments. Six Flags In connection with the Company’s former investment in the Six Flags theme parks located in Georgia and Texas (collectively, the “Parks”), in 1997, certain subsidiaries of the Company (including Historic TW and, in connection with the separation of Time Warner Cable Inc. in 2009, Warner Bros. Entertainment Inc.) agreed to guarantee (the “Six Flags Guarantee”) certain obligations of the partnerships that hold the Parks (the “Partnerships”) for the benefit of the limited partners in such Partnerships, including: annual payments made at the Parks or to the limited partners and additional obligations at the end of the respective terms for the Partnerships in 2027 and 2028 (the “Guaranteed Obligations”). The aggregate undiscounted estimated future cash flow requirements covered by the Six Flags Guarantee over the remaining term (through 2028) are $891 million (for a net present value of $433 million ). To date, no payments have been made by the Company pursuant to the Six Flags Guarantee. Six Flags Entertainment Corporation (formerly known as Six Flags, Inc. and Premier Parks Inc.) (“Six Flags”), which has the controlling interest in the Parks, has agreed, pursuant to a subordinated indemnity agreement (the “Subordinated Indemnity Agreement”), to guarantee the performance of the Guaranteed Obligations when due and to indemnify Historic TW, among others, if the Six Flags Guarantee is called upon. If Six Flags defaults in its indemnification obligations, Historic TW has the right to acquire control of the managing partner of the Parks. Six Flags’ obligations to Historic TW are further secured by its interest in all limited partnership units held by Six Flags. Because the Six Flags Guarantee existed prior to December 31, 2002 and no modifications to the arrangements have been made since the date the guarantee came into existence, the Company is required to continue to account for the Guaranteed Obligations as a contingent liability. Based on its evaluation of the current facts and circumstances surrounding the Guaranteed Obligations and the Subordinated Indemnity Agreement, the Company is unable to predict the loss, if any, that may be incurred under the Guaranteed Obligations, and no liability for the arrangements has been recognized at December 31, 2016 . Because of the specific circumstances surrounding the arrangements and the fact that no active or observable market exists for this type of financial guarantee, the Company is unable to determine a current fair value for the Guaranteed Obligations and related Subordinated Indemnity Agreement. • Post-production term advance obligations and other contingent commitments primarily include contingent payments for post-production term advance obligations on certain co-financing arrangements, as well as letters of credit, bank guarantees and surety bonds, which generally support performance and payments for a wide range of global contingent and firm obligations, including insurance, litigation appeals, real estate leases and other operational needs. Programming Licensing Backlog Programming licensing backlog represents the amount of future revenues not yet recorded from cash contracts for the licensing of theatrical and television product for pay cable, basic cable, network and syndicated television and OTT exhibition. Because backlog generally relates to contracts for the licensing of theatrical and television product that have already been produced, the recognition of revenue for such completed product is principally dependent on the commencement of the availability period for telecast under the terms of the related licensing agreement. Cash licensing fees are collected periodically over the term of the related licensing agreements. Backlog was approximately $6.8 billion and $6.3 billion at December 31, 2016 and 2015 , respectively. Included in these amounts is licensing of film product from the Warner Bros. segment to the Turner segment in the amount of $942 million and $619 million at December 31, 2016 and 2015 , respectively and to the Home Box Office segment in the amount of $689 million and $737 million at December 31, 2016 and 2015 , respectively. Certain filmed entertainment licensing contracts provide for additional revenues to be earned, and cash collected, based on the delivery of advertising spots to third parties. Backlog excludes estimates of such amounts. Contingencies In the ordinary course of business, the Company and its subsidiaries are defendants in or parties to various legal claims, actions and proceedings. These claims, actions and proceedings are at varying stages of investigation, arbitration or adjudication, and involve a variety of areas of law. On April 4, 2007, the National Labor Relations Board (“NLRB”) issued a complaint against CNN America Inc. (“CNN America”) and Team Video Services, LLC (“Team Video”) related to CNN America’s December 2003 and January 2004 terminations of its contractual relationships with Team Video, under which Team Video had provided electronic news gathering services in Washington, D.C. and New York, NY. The National Association of Broadcast Employees and Technicians, under which Team Video’s employees were unionized, initially filed charges of unfair labor practices with the NLRB in February 2004, alleging that CNN America and Team Video were joint employers, that CNN America was a successor employer to Team Video, and/or that CNN America discriminated in its hiring practices to avoid becoming a successor employer or due to specific individuals’ union affiliation or activities. In the complaint, the NLRB sought, among other things, the reinstatement of certain union members and monetary damages. On November 19, 2008, the presiding NLRB Administrative Law Judge (“ALJ”) issued a non-binding recommended decision and order finding CNN America liable. On September 15, 2014, a three-member panel of the NLRB affirmed the ALJ’s decision and adopted the ALJ’s order with certain modifications. On November 12, 2014, both CNN America and the NLRB General Counsel filed motions with the NLRB for reconsideration of the panel’s decision. On March 20, 2015, the NLRB granted the NLRB General Counsel’s motion for reconsideration to correct certain inadvertent errors in the panel’s decision, and it denied CNN America’s motion for reconsideration. On July 9, 2015, CNN America filed a notice of appeal with the U.S. Court of Appeals for the D.C. Circuit regarding the panel’s decision and the denial of CNN America’s motion for reconsideration. The Company establishes an accrued liability for legal claims when the Company determines that a loss is both probable and the amount of the loss can be reasonably estimated. Once established, accruals are adjusted from time to time, as appropriate, in light of additional information. The amount of any loss ultimately incurred in relation to matters for which an accrual has been established may be higher or lower than the amounts accrued for such matters. The Company has estimated a range of possible loss for legal claims for which the Company has determined a loss is probable or reasonably possible, including the matter disclosed above. The Company believes the estimate of the aggregate range of possible loss for such matters in excess of accrued liabilities is between $0 and $100 million at December 31, 2016 . The estimated aggregate range of possible loss is subject to significant judgment and a variety of assumptions. The matters represented in the estimated aggregate range of possible loss will change from time to time and actual results may vary significantly from the current estimate. In view of the inherent difficulty of predicting the outcome of litigation and claims, the Company often cannot predict what the eventual outcome of the pending matters will be, what the timing of the ultimate resolution of these matters will be, or what the eventual loss, fines or penalties related to each pending matter may be. An adverse outcome in one or more of these matters could be material to the Company’s results of operations or cash flows for any particular reporting period.

Condensed Financial Information of Parent Company Only Disclosure [Abstract]
SUPPLEMENTARY INFORMATION - CONDENSED CONSOLIDATING FINANCIAL STATEMENTS	Overview Set forth below are condensed consolidating financial statements presenting the financial position, results of operations and cash flows of (i) Time Warner Inc. (the “Parent Company”), (ii) Historic TW Inc. (in its own capacity and as successor by merger to Time Warner Companies, Inc.), Home Box Office, Inc., and Turner Broadcasting System, Inc., each a wholly owned subsidiary of the Parent Company (collectively, the “Guarantor Subsidiaries”), on a combined basis, (iii) the direct and indirect non-guarantor subsidiaries of the Parent Company (the “Non-Guarantor Subsidiaries”), on a combined basis, and (iv) the eliminations necessary to arrive at the information for Time Warner Inc. on a consolidated basis. The Guarantor Subsidiaries fully and unconditionally, jointly and severally guarantee securities issued under certain of the Company’s indentures on an unsecured basis. There are no legal or regulatory restrictions on the Parent Company’s ability to obtain funds from any of its wholly owned subsidiaries through dividends, loans or advances. Basis of Presentation In presenting the condensed consolidating financial statements, the equity method of accounting has been applied to (i) the Parent Company’s interests in the Guarantor Subsidiaries and (ii) the Guarantor Subsidiaries’ interests in the Non-Guarantor Subsidiaries, where applicable, even though all such subsidiaries meet the requirements to be consolidated under U.S. generally accepted accounting principles. All intercompany balances and transactions between the Parent Company, the Guarantor Subsidiaries and the Non-Guarantor Subsidiaries have been eliminated, as shown in the column “Eliminations.” The Parent Company’s accounting bases in all subsidiaries, including goodwill and identified intangible assets, have been “pushed down” to the applicable subsidiaries. Corporate overhead expenses have been reflected as expenses of the Parent Company and have not been allocated to the Guarantor Subsidiaries or the Non-Guarantor Subsidiaries. Interest income (expense) is determined based on outstanding debt and the relevant intercompany amounts at the respective subsidiary. All direct and indirect domestic subsidiaries are included in Time Warner Inc.’s consolidated U.S. tax return. In the condensed consolidating financial statements, tax provision has been allocated based on each such subsidiary’s relative pretax income to the consolidated pretax income. With respect to the use of certain consolidated tax attributes (principally operating and capital loss carryforwards), such benefits have been allocated to the respective subsidiary that generated the taxable income permitting such use (i.e., pro-rata based on where the income was generated). For example, to the extent a Non-Guarantor Subsidiary generated a gain on the sale of a business for which the Parent Company utilized tax attributes to offset such gain, the tax attribute benefit would be allocated to that Non-Guarantor Subsidiary. Deferred taxes of the Parent Company, the Guarantor Subsidiaries and the Non-Guarantor Subsidiaries have been determined based on the temporary differences between the book and tax basis of the respective assets and liabilities of the applicable entities. Certain transfers of cash between subsidiaries and their parent companies and intercompany dividends are reflected as cash flows from investing and financing activities in the accompanying Condensed Consolidating Statements of Cash Flows. All other intercompany activity is reflected in cash flows from operations. Management believes that the allocations and adjustments noted above are reasonable. However, such allocations and adjustments may not be indicative of the actual amounts that would have been incurred had the Parent Company, Guarantor Subsidiaries and Non-Guarantor Subsidiaries operated independently.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Consolidation	Basis of Consolidation The consolidated financial statements include all the assets, liabilities, revenues, expenses and cash flows of entities in which Time Warner has a controlling interest (“subsidiaries”). Intercompany accounts and transactions between consolidated entities have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and footnotes thereto. Actual results could differ from those estimates. Significant estimates and judgments inherent in the preparation of the consolidated financial statements include accounting for asset impairments, multiple-element transactions, allowances for doubtful accounts, depreciation and amortization, the determination of ultimate revenues as it relates to amortization or impairment of capitalized film and programming costs and participations and residuals, home video and videogame product returns, business combinations, pension and other postretirement benefits, equity-based compensation, income taxes, contingencies, litigation matters, reporting revenue for certain transactions on a gross versus net basis, and the determination of whether the Company should consolidate certain entities.
New Accounting Guidance	Accounting Guidance Adopted in 2016 Equity Method of Accounting In March 2016, guidance was issued that changes the requirements for equity method accounting when an investment qualifies for use of the equity method. The guidance (i) eliminates the need to retroactively apply the equity method of accounting upon qualifying for such treatment, (ii) requires that the cost of acquiring an additional interest in an investee be added to the basis of the previously held interest and (iii) requires that unrealized holding gains or losses for available-for-sale equity securities that qualify for the equity method of accounting be recognized in earnings at the date the investment becomes qualified for use of the equity method of accounting. The Company adopted this guidance on January 1, 2016 on a prospective basis and it did not impact the Company’s consolidated financial statements. Accounting Guidance Not Yet Adopted Simplifying the Accounting for Goodwill Impairment In January 2017, guidance was issued to simplify the accounting for goodwill impairment. The guidance removes the second step of the goodwill impairment test, which requires that a hypothetical purchase price allocation be performed to determine the amount of impairment, if any. Under this new guidance, a goodwill impairment charge will be based on the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance will become effective on a prospective basis for the Company on January 1, 2020 and is not expected to have a material impact on the Company’s consolidated financial statements. Definition of a Business In January 2017, guidance was issued that changes the definition of a business for accounting purposes. Under the new guidance, an entity first determines whether substantially all of the fair value of a set of assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set of assets is not deemed to be a business. If the threshold is not met, the entity then evaluates whether the set of assets meets the requirement to be deemed a business, which at a minimum, requires there to be an input and a substantive process that together significantly contribute to the ability to create outputs. The guidance will become effective on a prospective basis for the Company on January 1, 2018 and is not expected to have a material impact on the Company’s consolidated financial statements. Restricted Cash In November 2016, guidance was issued that requires that a statement of cash flows present the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total cash amounts shown on the statement of cash flows. The guidance will become effective on a retrospective basis for the Company on January 1, 2018 and is not expected to have a material impact on the Company’s consolidated financial statements. Intra-Entity Transfers of Assets Other than Inventory In October 2016, guidance was issued that requires entities to recognize the income tax consequences of an intercompany transfer of an asset other than inventory when the transfer occurs, rather than deferring the income tax consequences of the intercompany transfer of assets until the asset has been sold to a third party. The guidance will become effective on a modified retrospective basis for the Company on January 1, 2018 and is not expected to have a material impact on the Company’s consolidated financial statements. Classification of Certain Cash Receipts and Cash Payments In August 2016, guidance was issued that clarifies the presentation of certain cash receipts and payments in a company’s statement of cash flows. The guidance primarily relates to the classification of cash flows associated with certain (i) debt transactions, (ii) contingent consideration arrangements related to business combinations, (iii) insurance claims and policies, (iv) distributions received from equity method investees and (v) securitization transactions. The guidance will become effective on a retrospective basis for the Company on January 1, 2018 and is not expected to have a material impact on the Company’s consolidated financial statements. Share-Based Payments In March 2016, guidance was issued that changes the reporting for certain aspects of share-based payments. One aspect of the guidance, which became effective on a prospective basis on January 1, 2017, requires that the income tax effects of share-based awards be recognized in the income statement when the awards vest or are settled. Under the previous guidance, excess tax benefits and deficiencies were recognized in Additional paid-in capital in the Consolidated Balance Sheet. For the years ended December 31, 2016 and 2015 , the amount of excess tax benefits, net of deficiencies, recognized in Additional paid-in capital was $82 million and $150 million , respectively. In addition, because excess tax benefits are no longer recognized in Additional paid-in capital, such amounts are no longer included in the determination of assumed proceeds in applying the treasury stock method when computing earnings per share. Another aspect of the new guidance, which the Company adopted on a prospective basis on January 1, 2017, requires that excess tax benefits be classified as a cash flow from operating activities in the Consolidated Statement of Cash Flows. Under the previous guidance, excess tax benefits were classified as a cash flow from financing activities. Excess tax benefits presented as a cash flow from financing activities were $88 million , $151 million , and $179 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. The other aspects of this new guidance are not expected to have a material effect on the Company’s consolidated financial statements. Accounting for Leases In February 2016, guidance was issued regarding accounting for leases. The main difference between the current guidance and the new guidance is the recognition by the lessee of lease assets and liabilities for those leases it classified as operating leases under the current guidance. Under the new guidance, the recognition, measurement and presentation of expenses and cash flows arising from a lease as well as the lessor accounting model have not significantly changed from current guidance. This guidance also requires qualitative and quantitative disclosures of key information about leasing arrangements. The new guidance will become effective on a modified retrospective basis for the Company on January 1, 2019. The Company is still evaluating the impact of the new guidance on its consolidated financial statements. Because the Company is a party to more than 2,000 operating leases with future minimum rental commitments of $1.154 billion , it expects that the impact of recognizing lease assets and liabilities for these operating leases will be significant to the Company’s Consolidated Balance Sheet. Recognition and Measurement of Financial Assets and Liabilities In January 2016, guidance was issued that makes limited changes to the accounting for financial instruments. The changes primarily relate to (i) the requirement to measure equity investments in unconsolidated subsidiaries, other than those accounted for under the equity method of accounting, at fair value, with changes in the fair value recognized in earnings, (ii) an alternative approach for the measurement of equity investments that do not have a readily determinable fair value, (iii) the elimination of the other-than-temporary impairment model and its replacement with a requirement to perform a qualitative assessment to identify the impairment of equity investments, and a requirement to recognize impairment losses in earnings based on the difference between the fair value and the carrying value of the equity investment, (iv) the elimination of the requirement to disclose the methods and significant assumptions used to estimate the fair value of financial instruments measured at amortized cost, (v) the addition of a requirement to use the exit price concept when measuring the fair value of financial instruments for disclosure purposes and (vi) the addition of a requirement to present financial assets and financial liabilities separately in the notes to the financial statements, grouped by measurement category (e.g., fair value, amortized cost, lower of cost or market) and by form of financial asset (e.g., loans, securities). This guidance will become effective for the Company on January 1, 2018. The Company does not expect the new guidance to have a material impact on its consolidated financial statements. Revenue Recognition In May 2014, guidance was issued that establishes a new revenue recognition framework in GAAP for all companies and industries. The core principle of the new guidance is that an entity should recognize revenue from the transfer of promised goods or services to customers in an amount that reflects the consideration the entity expects to receive for those goods or services. The guidance includes a five-step framework to determine the timing and amount of revenue to recognize related to contracts with customers. In addition, this guidance requires new or expanded disclosures related to the judgments made by companies when following this framework. Based on the current guidance, the new framework will become effective on either a full or modified retrospective basis for the Company on January 1, 2018. Subsequent to the issuance of the May 2014 guidance, several clarifications and updates have been issued by the FASB on this topic, the most recent of which was issued in December 2016. Many of these clarifications and updates to the guidance, as well as a number of interpretive issues, apply to companies in the media and entertainment industry. The Company has made significant progress toward completing its assessment of the impact of adopting this new guidance, and the Company is finalizing its implementation plan. The Company currently does not believe that the adoption of the new guidance will have a material impact on the Company’s financial statements, principally because the Company does not expect significant changes in the way it will record subscription revenue, advertising revenue, and a significant portion of its content revenue. However, it is possible that the Company’s evaluation of the expected impact of the new guidance on certain transactions could change if there are additional interpretations of the new revenue guidance that are different from the Company’s preliminary conclusions. Although the Company currently does not expect the impact of adopting the new guidance to be material, there are several areas where the Company’s revenue recognition is expected to change as compared with historical GAAP. The more significant of these areas are as follows: i. Renewals of Licenses of Intellectual Property - Under guidance currently in effect, when the term of an existing license agreement is extended, without any other changes to the provisions of the license, revenue for the renewal period is recognized on the date the renewal is agreed to contractually. Under the new guidance, revenue for the renewed license term will not be recognized until the date the renewal term begins. This change will result in delayed revenue recognition as compared with current revenue recognition guidance. The Company expects that this change will primarily impact the Warner Bros. segment, but it will also, to a lesser degree, impact the Home Box Office and Turner segments. ii. License of Content Library - Under guidance currently in effect, when a company licenses a completed library of content and agrees to refresh the library with new content as it becomes available, and the licensee is not entitled to a refund if no further library titles are delivered, revenue is recognized once access to the library is granted to the licensee. Under the new guidance, because there is an implicit obligation for the company to refresh the library with additional content in the future, the company will need to estimate the additional content it will deliver in the future and allocate a portion of the transaction price to that content. As compared with current guidance, this results in a deferral of a portion of the transaction price until delivery of future library content. The Company expects this change will primarily impact the Home Box Office segment. iii. Licenses of Symbolic Intellectual Property - Certain intellectual property, such as brands, tradenames and logos, is categorized in the new guidance as symbolic. An assumption inherent in the new guidance is that a licensee’s ability to derive benefit from a license of symbolic intellectual property depends on the licensor continuing to support or maintain the intellectual property throughout the license term. Accordingly, under the new guidance, revenue from licenses of symbolic intellectual property is recognized over the corresponding license term. In certain arrangements where the Company has no remaining performance obligations, under the guidance currently in effect, revenue from licenses of symbolic intellectual property is recognized at the inception of the license term. Therefore, the new guidance will result in a deferral of revenue recognition as compared to current guidance. This change will primarily impact the Warner Bros. segment. The evaluation of the impact of the new guidance on certain other transactions is still in process; however, the Company does not expect the completion of that evaluation to impact the Company’s conclusion that the adoption will not have a material impact on the Company’s financial statements. The Company currently expects to adopt the standard in 2018 using the modified retrospective method of adoption. However, the transition method ultimately selected could be affected by the Company’s pending merger with AT&T Inc. (“AT&T”) if the merger closes prior to the adoption of the new guidance. For more information regarding the AT&T merger, see Note 2.
Cash And Cash Equivalents	Cash and Equivalents Cash equivalents consist of investments that are readily convertible into cash and have original maturities of three months or less. Cash equivalents are carried at cost, which approximates fair value. The Company monitors concentrations of credit risk with respect to Cash and equivalents by placing such balances with higher quality financial institutions or investing such amounts in liquid, short-term, highly-rated instruments or investment funds holding similar instruments. As of December 31, 2016 , the majority of the Company’s Cash and equivalents were invested with banks with a credit rating of at least A and in Rule 2a-7 money market mutual funds. At December 31, 2016 , the Company did not have more than $500 million invested in any single bank or money market mutual fund.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company monitors customer credit risk related to accounts receivable, including unbilled trade receivables primarily related to the distribution of television product. Significant judgments and estimates are involved in evaluating if such amounts will ultimately be fully collected. Each of the Company’s businesses maintains a comprehensive approval process prior to issuing credit to third-party customers. Counterparties that are determined to be of a higher risk are evaluated to assess whether the credit terms previously granted to them should be modified. The Company monitors customers’ accounts receivable aging, and a provision for estimated uncollectible amounts is maintained based on customer payment levels, historical experience and management’s views on trends in the overall receivable agings. In addition, for larger accounts, the Company performs analyses of risks on a customer-specific basis. At December 31, 2016 and 2015 , total reserves for doubtful accounts were approximately $193 million and $180 million , respectively. For the years ended December 31, 2016 and 2015 , the Company recognized $38 million and $63 million of bad debt expense, respectively. For the year ended December 31, 2014 , the Company recognized $20 million of income related to bad debt primarily due to the reversal of a reserve related to a Warner Bros. receivable.
Consolidation	Consolidation Time Warner consolidates all entities in which it has a controlling voting interest and all variable interest entities (“VIEs”) in which the Company is deemed to be the primary beneficiary. Entities determined to be VIEs primarily consist of HBO Latin America Group (“HBO LAG”) and Hudson Yards North Tower Holdings LLC (“HYNTH”), the limited liability company involved in the construction and development of the Company’s new headquarters building at Hudson Yards.
Investments	Investments The Company’s investments consist of (i) investments carried at fair value, including available-for-sale securities and certain deferred compensation-related investments, (ii) investments accounted for using the cost method of accounting and (iii) investments accounted for using the equity method of accounting. The Company regularly reviews its investments for impairment, including when the carrying value of an investment exceeds its market value. If the Company determines that an investment has sustained an other-than-temporary decline in its value, the investment is written down to its fair value by a charge to earnings that is included in Other loss, net. Factors that are considered by the Company in determining whether an other-than-temporary decline in value has occurred include (i) the market value of the security in relation to its cost basis, (ii) the financial condition of the investee and (iii) the Company’s intent and ability to retain the investment for a sufficient period of time to allow for recovery in the market value of the investment. In evaluating the factors described above for available-for-sale securities, the Company presumes a decline in value to be other-than-temporary if the quoted market price of the security is 20% or more below the investment’s cost basis for a period of six months or more (the “20% criterion”) or the quoted market price of the security is 50% or more below the security’s cost basis at any quarter end (the “50% criterion”). However, the presumption of an other-than-temporary decline in these instances may be overcome if there is persuasive evidence indicating that the decline is temporary in nature (e.g., the investee’s operating performance is strong, the market price of the investee’s security is historically volatile, etc.). Additionally, there may be instances in which impairment losses are recognized even if the 20% and 50% criteria are not satisfied (e.g., if there is a plan to sell the security in the near term and the fair value is below the Company’s cost basis). For investments accounted for using the cost or equity method of accounting, the Company evaluates information available (e.g., budgets, business plans, financial statements, etc.) in addition to quoted market prices, if any, in determining whether an other-than-temporary decline in value exists. Factors indicative of an other-than-temporary decline include recurring operating losses, credit defaults and subsequent rounds of financing at an amount below the cost basis of the Company’s investment. For more information, see Note 5. Investments Investments in common stock in companies in which Time Warner has significant influence, but less than a controlling voting interest, are accounted for using the equity method. Significant influence is generally presumed to exist when Time Warner owns between 20% and 50% of the voting interests in the investee, holds substantial management rights or holds an interest of less than 20% in an investee that is a limited liability partnership or limited liability corporation that is treated as a flow-through entity. Under the equity method of accounting, only Time Warner’s investment in and amounts due to and from the equity investee are included in the Consolidated Balance Sheet; only Time Warner’s share of the investee’s earnings (losses) is included in the Consolidated Statement of Operations; and only the dividends, cash distributions, loans or other cash received from the investee, additional cash investments, loan repayments or other cash paid to the investee are included in the Consolidated Statement of Cash Flows. If previous equity method losses have reduced the carrying value of the Company’s equity method investment to zero, the Company continues to record its share of equity method losses to the extent it has (i) other investments in the investee, (ii) guaranteed obligations of the investee or (iii) committed to provide further financial support for the investee. Investments in companies in which Time Warner does not have a controlling voting interest or over which it is unable to exert significant influence are generally accounted for at fair value if the investments are publicly traded. If the investment or security is not publicly traded, the investment is accounted for at cost. Unrealized gains and losses on investments accounted for at fair value are reported, net of tax, in Accumulated other comprehensive loss, net. Dividends and other distributions of earnings from investments in companies in which Time Warner does not have a controlling voting interest or over which it is unable to exert significant influence are included in Other loss, net, when declared. For more information, see Notes 4 and 5. The company regularly reviews its investments for impairment. See “Asset Impairments” below for additional information. Available-for-sale securities are recorded at fair value in the Consolidated Balance Sheet, and the realized gains and losses are included as a component of Other loss, net in the Consolidated Statement of Operations.
Foreign Currency Translation	Foreign Currency Translation Financial statements of subsidiaries operating outside the United States whose functional currency is not the U.S. Dollar are translated at the rates of exchange on the balance sheet date for assets and liabilities and at average rates of exchange for revenues and expenses during the period. Translation gains or losses on assets and liabilities are included as a component of Accumulated other comprehensive loss, net.
Derivative Instruments	Derivative Instruments The Company uses derivative instruments principally to manage the risk associated with movements in foreign currency exchange rates, and recognizes all derivative instruments on the Consolidated Balance Sheet at fair value. Changes in fair value of derivative instruments that qualify for hedge accounting will either be offset against the change in fair value of the hedged assets or liabilities through earnings or recognized in shareholders’ equity as a component of Accumulated other comprehensive loss, net, until the hedged item is recognized in earnings, depending on whether the derivative instrument is being used to hedge changes in fair value or cash flows. For qualifying hedge relationships, the Company excludes the impact of forward points or option premiums from its assessment of hedge effectiveness and recognizes changes in the fair value of a derivative instrument due to forward points or option premiums in Other income (loss), net each quarter. The ineffective portion of a derivative instrument’s change in fair value is immediately recognized in earnings. For those derivative instruments that do not qualify for hedge accounting, changes in fair value are recognized immediately in earnings. See Note 8 for additional information regarding derivative instruments held by the Company and risk management strategies.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost. Additions to property, plant and equipment generally include material, labor and overhead. Time Warner also capitalizes certain costs associated with coding, software configuration, upgrades and enhancements incurred for the development of internal use software. Depreciation is recorded on a straight-line basis over estimated useful lives. Leasehold improvements are depreciated over the lesser of the estimated useful life of the improvement or the term of the applicable lease. Time Warner periodically evaluates the depreciation periods of property, plant and equipment to determine whether a revision to its estimates of useful lives is warranted. Land is not depreciated.
Goodwill and Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets Goodwill and indefinite-lived intangible assets, primarily tradenames, are tested annually for impairment as of December 31 or earlier upon the occurrence of certain events or substantive changes in circumstances. Goodwill is tested for impairment at the reporting unit level. A reporting unit is either the “operating segment level,” such as Warner Bros. Entertainment Inc. (“Warner Bros.”), Home Box Office, Inc. (“Home Box Office”) and Turner Broadcasting System, Inc. (“Turner”), or one level below, which is referred to as a “component” (e.g., Warner Bros. Theatrical, Warner Bros. Television). The level at which the impairment test is performed requires judgment as to whether the components constitute a self-sustaining business and, if so, whether their operations are similar such that they should be aggregated for purposes of the impairment test. For purposes of the goodwill impairment test, management has concluded that the operations below the operating segment level met the criteria to be aggregated and therefore has determined its reporting units are the same as its operating segments. In assessing Goodwill for impairment, the Company has the option to first perform a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company is not required to perform any additional tests in assessing Goodwill for impairment. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, then it is required to perform the first step of a two-step impairment review process. The first step of the two-step process involves a comparison of the estimated fair value of a reporting unit to its carrying amount. In performing the first step, the Company generally determines the fair value of a reporting unit using a discounted cash flow (“DCF”) analysis and, in certain cases, a combination of a DCF analysis and a market-based approach. Determining fair value requires the exercise of significant judgment, including judgments about appropriate discount rates, perpetual growth rates, the amount and timing of expected future cash flows, as well as relevant comparable public company earnings multiples. The cash flows employed in the DCF analyses are based on the Company’s most recent budgets and long range plans and perpetual growth rates are assumed for years beyond the current long range plan period. Discount rate assumptions are based on an assessment of market rates, capital structures and the risk inherent in the future cash flows included in the budgets and long range plans. For 2016 , the Company elected to perform a qualitative assessment of impairment of Goodwill and concluded that it was more likely than not that the fair value of each reporting unit was in excess of its respective carrying value. Accordingly, the 2016 assessment did not result in any impairments of the Company’s Goodwill. In reaching this conclusion, the Company considered the results of prior year’s quantitative assessment and underlying trends and assumptions used in determining fair value, including the value proposed by AT&T in connection with the pending AT&T merger. In assessing other intangible assets not subject to amortization for impairment, the Company also has the option to perform a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of such an intangible asset is less than its carrying amount. If the Company determines that it is not more likely than not that the fair value of such an intangible asset is less than its carrying amount, then the Company is not required to perform any additional tests for assessing those intangible assets for impairment. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, then it is required to perform a quantitative impairment test that involves a comparison of the estimated fair value of the intangible asset with its carrying value. When performing the quantitative impairment test on other intangible assets not subject to amortization, the Company determines fair value using a DCF valuation analysis, which is based on the “relief from royalty” methodology. Discount rate assumptions are based on an assessment of the risk inherent in the projected future cash flows generated by the respective intangible assets. Also subject to judgment are assumptions about royalty rates, which are based on the estimated rates at which similar tradenames are being licensed in the marketplace. If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. In 2016 , the Company elected to perform a qualitative assessment for substantially all of its intangible assets not subject to amortization and concluded that it was more likely than not the fair value of each of the Company’s intangible assets not subject to amortization was in excess of its respective carrying value. Intangible Assets Time Warner has a significant number of intangible assets, including acquired film and television libraries and other copyrighted products and tradenames. Time Warner does not recognize the fair value of internally generated intangible assets. Intangible assets acquired in business combinations are recorded at the acquisition date fair value in the Company’s Consolidated Balance Sheet. Acquired film libraries are amortized using the film forecast computation model. For more information, see “Film and Television Production Cost Recognition, Participations and Residuals and Impairments” and Note 3. Certain intangible assets are deemed to have finite lives and, accordingly, are amortized over their estimated useful lives, while others are deemed to be indefinite-lived and therefore are not amortized. Goodwill and indefinite-lived intangible assets, primarily certain tradenames, are tested annually for impairment during the fourth quarter, or earlier upon the occurrence of certain events or substantive changes in circumstances.
Long-Lived Assets	Long-Lived Assets Long-lived assets such as property, plant and equipment and finite-lived intangible assets (e.g., tradenames, customer lists and film libraries, do not require that an annual impairment test be performed; instead, long-lived assets are tested for impairment upon the occurrence of a triggering event. Triggering events include the more likely than not disposal of a portion of such assets or the occurrence of an adverse change in the market involving the business employing the related assets. Once a triggering event has occurred, the impairment test is based on whether the intent is to hold the asset for continued use or to hold the asset for sale. The impairment test for assets held for continued use requires a comparison of cash flows expected to be generated over the useful life of an asset or group of assets (“asset group”) against the carrying value of the asset group. An asset group is established by identifying the lowest level of cash flows generated by the asset or group of assets that are largely independent of the cash flows of other assets. If the intent is to hold the asset group for continued use, the impairment test first requires a comparison of estimated undiscounted future cash flows generated by the asset group against its carrying value. If the carrying value exceeds the estimated undiscounted future cash flows, an impairment would be measured as the difference between the estimated fair value of the asset group and its carrying value. Fair value is generally determined by discounting the future cash flows associated with that asset group. If the intent is to hold the asset group for sale and certain other criteria are met (e.g., the asset can be disposed of currently, appropriate levels of authority have approved the sale, and there is an active program to locate a buyer), the impairment test involves comparing the asset group’s carrying value to its estimated fair value. To the extent the carrying value is greater than the estimated fair value, an impairment loss is recognized for the difference. Significant judgments in this area involve determining the appropriate asset group level at which to test, determining whether a triggering event has occurred, determining the future cash flows for the assets involved and selecting the appropriate discount rate to be applied in determining estimated fair value. For more information, see Note 3. The majority of the Company’s non-financial instruments, which include goodwill, intangible assets, inventories and property, plant and equipment, are not required to be carried at fair value on a recurring basis. However, if certain triggering events occur (or at least annually for goodwill and indefinite-lived intangible assets), a non-financial instrument is required to be evaluated for impairment. If the Company determines that the non-financial instrument is impaired, the Company would be required to write down the non-financial instrument to its fair value.
Accounting for Pension Plans	Accounting for Pension Plans The Company and certain of its subsidiaries have both funded and unfunded defined benefit pension plans, the substantial majority of which are noncontributory, covering a majority of domestic employees and, to a lesser extent, have various defined benefit plans, primarily noncontributory, covering certain international employees. Pension benefits are based on formulas that reflect the participating employees’ qualifying years of service and compensation. Time Warner’s largest defined benefit pension plan is closed for new employees and frozen to future benefit accruals. Time Warner uses a December 31 measurement date for its plans. The pension expense recognized by the Company is determined using certain assumptions, including the expected long-term rate of return on plan assets, the interest factor implied by the discount rate and the rate of compensation increases. For more information, see Note 14.
Equity-Based Compensation	Equity-Based Compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost is recognized in Costs of revenues or Selling, general and administrative expenses depending on the job function of the grantee on a straight-line basis (net of estimated forfeitures) from the date of grant over the period during which an employee is required to provide services in exchange for the award. The total grant-date fair value of an equity award granted to an employee who has reached a specified age and years of service as of the grant date is recognized as compensation expense immediately upon grant as there is no required service period. The grant-date fair value of a restricted stock unit (“RSU”) is determined based on the closing sale price of the Company’s common stock on the NYSE Composite Tape on the date of grant. Performance stock units (“PSUs”) are subject to a performance condition such that the number of PSUs that ultimately vest generally depends on the adjusted earnings per share (“Adjusted EPS”) achieved by the Company during a three -year performance period compared to targets established at the beginning of the period. The PSUs are also subject to a market condition and the number of PSUs that vest can be increased or decreased based on the Company’s cumulative total shareholder return (“TSR”) relative to the TSR of the other companies in the S&P 500 Index for the performance period. Because the terms of the PSUs provide discretion to make certain adjustments to the performance calculation, the service inception date of these awards precedes the grant date. Accordingly, the Company recognizes compensation expense beginning on the service inception date and remeasures the fair value of the PSU until a grant date occurs, which is typically after the completion of the required service period. PSUs, as well as RSUs granted to certain senior executives, also are subject to a performance condition based on an adjusted net income target for a one -year period that, if not achieved, will result in the forfeiture of the awards. The grant-date fair value of a stock option is estimated using the Black-Scholes option-pricing model . Because the Black-Scholes option-pricing model requires the use of subjective assumptions, changes in these assumptions can materially affect the fair value of the stock options. The Company determines the volatility assumption for these stock options using implied volatilities data from its traded options. The expected term, which represents the period of time that stock options granted are expected to be outstanding, is estimated based on the historical exercise behavior of Time Warner employees. Groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The risk-free rate assumed in valuing the options is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option. The Company determines the expected dividend yield percentage by dividing the expected annual dividend by the market price of Time Warner common stock at the date of grant. For more information, see Note 13. For accounting purposes, the Company records equity-based compensation expense and a related deferred tax asset for the future tax deductions it may receive. For income tax purposes, the Company receives a tax deduction equal to the stock price on the date that an RSU (or PSU) vests or the excess of the stock price over the exercise price of an option upon exercise. The deferred tax asset consists of amounts relating to individual unvested and/or unexercised equity-based compensation awards; accordingly, deferred tax assets related to certain equity awards may currently be in excess of the tax benefit ultimately received. The applicable accounting rules require that the deferred tax asset related to an equity-based compensation award be reduced only at the time the award vests (in the case of an RSU or PSU), is exercised (in the case of a stock option) or otherwise expires or is canceled. This reduction is recorded as an adjustment to Additional paid-in capital (“APIC”), to the extent that the realization of excess tax deductions on prior equity-based compensation awards were recorded directly to APIC. The cumulative amount of such excess tax deductions is referred to as the Company’s “APIC Pool.” Any shortfall balance recognized in excess of the Company’s APIC Pool is charged to Income tax provision in the Consolidated Statement of Operations. The Company’s APIC Pool was sufficient to absorb any shortfalls such that no shortfalls were charged to the Income tax provision during the years ended December 31, 2016 , 2015 and 2014 .
Revenue Recognition	Revenue The Company generates revenue primarily from content production and distribution (i.e., Content Revenue), providing programming to cable system operators, satellite service distributors, telephone companies and virtual multichannel video programming distributors (collectively, “affiliates”) and digital distributors that have contracted to receive and distribute this programming to their subscribers (i.e., Subscription Revenue) and the sale of advertising on the Company’s television networks and digital properties and the digital properties it manages and/or operates for others (i.e., Advertising Revenue). Content Revenue Feature films typically are produced or acquired for initial exhibition in theaters, followed by distribution, generally commencing within three years of such initial exhibition, through sales of feature films in physical format, electronic sell-through, video-on-demand, OTT services, premium cable, basic cable and broadcast networks. Revenues from film rentals by theaters are recognized as the films are exhibited. Revenues from sales of feature films in physical format are recognized at the later of the delivery date or the date that the DVDs or Blu-ray Discs are made widely available for sale or rental by retailers based on gross sales less a provision for estimated returns, rebates and pricing allowances. Revenues from the licensing of feature films for electronic sell-through or video-on-demand are recognized when the product has been purchased by and made available to the consumer to either download or stream. Revenues from the distribution of theatrical product through OTT services, premium cable, basic cable and broadcast networks are recognized when the films are available to the licensee. Television programs and series are initially produced for broadcast networks, cable networks, first-run television syndication or OTT services and may be subsequently licensed for international or domestic cable, syndicated television and OTT services, as well as sold on home video and via electronic delivery. Revenues from the distribution of television programming through broadcast networks, cable networks, first-run syndication and OTT services are recognized when the programs or series are available to the licensee, except for consideration to be received from the exhibition of advertising, where the revenue is valued and recognized when the related advertisements are exhibited. In certain circumstances, pursuant to the terms of the applicable contractual arrangements, the availability dates granted to customers may precede the date the Company may bill the customers for these sales. Unbilled accounts receivable, which primarily relate to the distribution of television product at Warner Bros., totaled $4.573 billion and $4.057 billion at December 31, 2016 and December 31, 2015 , respectively. Included in the unbilled accounts receivable at December 31, 2016 was $2.687 billion that is to be billed in the next twelve months. Similar to theatrical home video sales, revenues from sales of television programming in physical format are recognized at the later of the delivery date or the date that the DVDs or Blu-ray Discs are made widely available for sale or rental by retailers based on gross sales less a provision for estimated returns, rebates and pricing allowances. Revenues from the licensing of television programs and series for electronic sell-through or video-on-demand are recognized when the product has been purchased by and made available to the consumer to either download or stream. Revenues from the distribution of television programming through OTT services are recognized when the television programs or series are available to the licensee. Upfront or guaranteed payments for the licensing of intellectual property are recognized as revenue when (i) an arrangement has been signed with a customer, (ii) the customer’s right to use or otherwise exploit the intellectual property has commenced and there is no requirement for significant continued performance by the Company, (iii) licensing fees are either fixed or determinable and (iv) collectability of the fees is reasonably assured. In the event any significant continued performance is required in these arrangements, revenue is allocated to each applicable element and recognized when the related services are performed. Revenues from the sales of console videogames are recognized at the later of the delivery date or the date that the product is made widely available for sale or rental by retailers based on gross sales less a provision for estimated returns, rebates and pricing allowances. Subscription Revenue Subscription revenues from the Company’s cable networks and premium pay and basic tier television services are recognized over the license period as programming is provided to affiliates based on negotiated contractual programming rates. When a distribution contract with an affiliate has expired and a new distribution contract has not been executed, revenues are based on estimated rates, giving consideration to factors including the previous contractual rates, inflation, current payments by the affiliate and the status of the negotiations on a new contract. When the new distribution contract terms are finalized, an adjustment to Subscription revenues is recorded, if necessary, to reflect the new terms. Such adjustments historically have not been significant. Subscription revenues from OTT services (e.g., HBO NOW) are recognized as programming services are provided to customers. Advertising Revenue Advertising revenues are recognized, net of agency commissions, in the period that the advertisements are aired. If there is a targeted audience guarantee, revenues are recognized for the actual audience delivery and revenues are deferred for any shortfall until the guaranteed audience delivery is met, typically by providing additional advertisements. Advertising revenues from digital properties are recognized as impressions are delivered or the services are performed. Sales Returns and Pricing Rebates Management’s estimate of product sales that will be returned and pricing rebates to grant is an area of judgment affecting Revenues and Net income. In estimating product sales that will be returned, management analyzes vendor sales of the Company’s product, historical return trends, current economic conditions, and changes in customer demand. Based on this information, management reserves a percentage of any product sales that provide the customer with the right of return. The provision for such sales returns is reflected as a reduction in the revenues from the related sale. In estimating the reserve for pricing rebates, management considers the terms of the Company’s agreements with its customers that contain targets which, if met, would entitle the customer to a rebate. In those instances, management evaluates the customer’s actual and forecasted purchases to determine the appropriate reserve. At December 31, 2016 and 2015 , total reserves for sales returns (which also reflects reserves for certain pricing allowances provided to customers) primarily related to home entertainment products (e.g., DVDs, Blu-ray Discs and videogames) and were $788 million and $875 million , respectively. An incremental change of 1% in the Company’s estimated sales returns rate (i.e., provisions for returns divided by gross sales of related product) would have resulted in an approximate $32 million impact on the Company’s total Revenues for the year ended December 31, 2016 . This revenue impact would have been partially offset by a corresponding impact on related expenses depending on the margin associated with a specific film or videogame and other factors. Gross versus Net Revenue Recognition In the normal course of business, the Company may act as an intermediary or an agent with respect to the sale of third-party products or services (e.g., arrangements where Warner Bros. distributes a film owned by a third party). In addition, the Company may use an intermediary to sell its own products or services (e.g., arrangements involving the distribution of HBO NOW). In connection with these arrangements, the Company must determine whether to report revenue based on the gross amount billed to the ultimate customer or on the net amount received from the customer after commissions and other payments to third parties. To the extent revenues are recorded on a gross basis, any commissions or other payments to third parties are recorded as expense so that the net amount (gross revenues less expense) is reflected in Operating Income. Accordingly, the impact on Operating Income is the same whether the Company records revenue on a gross or net basis. The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether the Company is acting as the principal or an agent in the transaction. If the Company is acting as a principal in a transaction, the Company reports revenue on a gross basis. If the Company is acting as an agent in a transaction, the Company reports revenue on a net basis. The determination of whether the Company is acting as a principal or an agent in a transaction involves judgment and is based on an evaluation of the terms of an arrangement. The Company serves as the principal in transactions in which it has substantial risks and rewards of ownership. For example, Warner Bros. acts as an intermediary when it provides distribution services for independent third-party companies for the worldwide distribution of theatrical films, home video, television programs and/or videogames. The independent third-party company may retain final approval over the distribution, marketing, advertising and publicity for each film or videogame in all media, including the timing and extent of the releases, the pricing and packaging of packaged goods units and approval of all television licenses. Warner Bros. records revenue generated in these distribution arrangements on a gross basis when it (i) is the merchant of record for the licensing arrangements, (ii) is the licensor/contracting party, (iii) provides the materials to licensees, (iv) handles the billing and collection of all amounts due under such arrangements and (v) bears the risk of loss related to distribution advances and/or the packaged goods inventory. If Warner Bros. does not bear the risk of loss as described in the previous sentence, the arrangements are accounted for on a net basis. Multiple-Element Transactions In the normal course of business, the Company enters into multiple-element transactions that involve making judgments about allocating the consideration to the various elements of the transactions. While the more common type of multiple-element transactions encountered by the Company involve the sale or purchase of multiple products or services (e.g., licensing multiple film titles in a single arrangement), multiple-element transactions can also involve contemporaneous purchase and sales transactions, the settlement of an outstanding dispute contemporaneous with the purchase of a product or service, as well as investing in an investee while at the same time entering into an operating agreement. In accounting for multiple-element transactions, judgment must be exercised in identifying the separate elements in a bundled transaction as well as determining the values of these elements. These judgments can impact the amount of revenues, expenses and net income recognized over the term of the contract, as well as the period in which they are recognized. In determining the value of the respective elements, the Company refers to quoted market prices (where available), independent appraisals (where available), historical and comparable cash transactions or its best estimate of selling price. Other indicators of value include the existence of price protection in the form of “most-favored-nation” clauses or similar contractual provisions and individual elements whose values are dependent on future performance (and based on independent factors). Further, in such transactions, evidence of value for one element of a transaction may provide support that value was not transferred from one element in a transaction to another element in a transaction.
Cost of Sales	Film and Television Production Cost Recognition, Participations and Residuals and Impairments Film and television production costs include the unamortized cost of completed theatrical films and television episodes, theatrical films and television series in production and undeveloped film and television rights. Film and television production costs are stated at the lower of cost, less accumulated amortization, or fair value. The amount of capitalized film and television production costs recognized as Costs of revenues for a given period is determined using the film forecast computation method. Under this method, the amortization of capitalized costs and the accrual of participations and residuals is based on the proportion of the film’s revenues recognized for such period to the film’s estimated remaining ultimate revenues (i.e., the total revenue to be received throughout a film’s life cycle). The process of estimating a film’s ultimate revenues requires the Company to make a series of significant judgments relating to future revenue generating activities associated with a particular film and is important for two reasons. First, while a film or television series is being produced and the related costs are being capitalized, as well as at the time the film or television series is released, it is necessary for management to estimate the ultimate revenues, less additional costs to be incurred (including exploitation and participation costs), in order to determine whether the value of a film or television series is impaired and requires an immediate write-off of unrecoverable film and television production costs down to fair value. Second, it is necessary for management to determine, using the film forecast computation method, the amount of capitalized film and television production costs and the amount of participations and residuals to be recognized as Costs of revenues for a given film or television series in a particular period. To the extent that the ultimate revenues are adjusted, the resulting gross margin reported on the exploitation of that film or television series in a period is also adjusted. Prior to the theatrical release of a film, management bases its estimates of ultimate revenues for each film on factors such as the historical performance of similar films, the star power of the lead actors, the rating and genre of the film, pre-release market research (including test market screenings) and the expected number of theaters in which the film will be released. In the absence of revenues directly related to the exhibition of a film or television program that is owned by the Company on the Company’s television networks or premium pay television or OTT services, management estimates a portion of the unamortized costs that are representative of the utilization of that film or television program in that exhibition and expenses such costs as the film or television program is exhibited. The period over which ultimate revenues are estimated is generally not to exceed ten years from the initial release of a motion picture or from the date of delivery of the first episode of an episodic television series. For an episodic television series still in production, the period over which ultimate revenues are estimated cannot exceed five years from the date of delivery of the most recent episode. Management updates such estimates based on information available during the film’s production and, upon release, the actual results of each film. Changes in estimates of ultimate revenues from period to period affect the amount of production costs amortized in a given period and, therefore, could have an impact on the segment’s financial results for that period. For example, prior to a film’s release, the Company often will test market the film to the film’s targeted demographic. If the film is not received favorably, the Company may (i) reduce the film’s estimated ultimate revenues, (ii) revise the film, which could cause the production costs to increase, or (iii) perform a combination of both. Similarly, a film that generates lower-than-expected theatrical revenues in its initial weeks of release would have its theatrical, home video and television distribution ultimate revenues adjusted downward. A failure to adjust for a downward change in estimates of ultimate revenues would result in the understatement of production costs amortization for the period. The Company recorded production cost amortization of $4.745 billion , $4.384 billion and $4.229 billion in 2016 , 2015 and 2014 , respectively. Included in production cost amortization are theatrical film impairments, primarily related to pre-release films, of $69 million , $80 million and $86 million in 2016 , 2015 and 2014 , respectively. Licensed Programming Inventory Cost Recognition and Impairment In the normal course of business, the Company’s Turner and Home Box Office segments enter into agreements to license programming exhibition rights from licensors. A programming inventory asset related to these rights and a corresponding liability payable to the licensor are recorded (on a discounted basis if the license agreements are long-term) when (i) the cost of the programming is reasonably determined, (ii) the programming material has been accepted in accordance with the terms of the agreement, (iii) the programming is available for its first showing or telecast, and (iv) the license period has commenced. There are variations in the amortization methods of these rights, depending on whether the network is advertising-supported (e.g., TNT and TBS) or not advertising-supported (e.g., HBO and Turner Classic Movies). For the Company’s advertising-supported networks, the Company’s general policy is to amortize each program’s costs on a straight-line basis (or per-play basis, if greater) over its license period. However, for certain types of programming, the initial airing has more value than subsequent airings. In these circumstances, the Company uses an accelerated method of amortization. For example, if the Company is licensing the right to air a movie multiple times over a certain period, the movie is being shown for the first time on a Company network (a “Network Movie Premiere”) and the Network Movie Premiere advertising is sold at a premium rate, a larger portion of the movie’s programming inventory cost is amortized upon the initial airing of the movie, with the remaining cost amortized on a straight-line basis (or per-play basis, if greater) over the remaining license period. The accelerated amortization upon the first airing versus subsequent airings is determined based on a study of historical and estimated future advertising sales for similar programming. For rights fees paid for sports programming arrangements (e.g., National Basketball Association, The National Collegiate Athletic Association (“NCAA”) Men’s Division I Basketball championship events (the “NCAA Tournament”) and Major League Baseball), such rights fees are amortized using a revenue-forecast model, in which the rights fees are amortized using the ratio of current period advertising revenue to total estimated remaining advertising revenue over the term of the arrangement. For premium pay television and OTT services that are not advertising-supported, each licensed program’s costs are amortized on a straight-line basis over its license period or estimated period of use, beginning with the month of initial exhibition. When the Company has the right to exhibit feature theatrical programming in multiple windows over a number of years, the Company uses historical audience viewership as its basis for determining the amount of programming amortization attributable to each window. For programming licensed in exchange, in part, for advertising services, the Company recognizes programming inventory and deferred advertising revenue at the estimated fair value when the programming is available for telecast. Such programming inventory is amortized in the same manner as the non-advertising component of the licensed programming. The Company carries its licensed programming inventory at the lower of unamortized cost or estimated net realizable value. For networks that generate both Advertising and Subscription revenues (e.g., TBS and TNT), the Company generally evaluates the net realizable value of unamortized programming costs based on the network’s programming taken as a whole. In assessing whether the programming inventory for a particular advertising-supported network is impaired, the Company determines the net realizable value for all of the network’s programming inventory based on a projection of the network’s profitability. Similarly, for premium pay television and OTT services that are not advertising-supported, the Company performs its evaluation of the net realizable value of unamortized programming costs based on the premium pay television and OTT services’ licensed programming taken as a whole. Specifically, the Company determines the net realizable value for all of its premium pay television and OTT service licensed programming based on projections of estimated Subscription revenues less certain costs of delivering and distributing the licensed programming. However, changes in management’s intended usage of a specific program, such as a decision to no longer exhibit that program and forego the use of the rights associated with the program license, would result in a reassessment of that program’s net realizable value, which could result in an impairment. In determining the fair value of its theatrical films, the Company employs a DCF methodology that includes cash flow estimates of a film’s ultimate revenue and costs as well as a discount rate. The discount rate utilized in the DCF analysis is based on the weighted average cost of capital of the respective business (e.g., Warner Bros.) plus a risk premium representing the risk associated with producing a particular theatrical film. The fair value of any theatrical films and television programs that management plans to abandon is zero . Because the primary determination of fair value is made using a DCF model, the resulting fair value is considered a Level 3 measurement.
Inventory	Other Inventory Inventories other than film and television production costs and licensed programming inventory consist primarily of DVDs, Blu-ray Discs and videogame development costs and are stated at the lower of cost or net realizable value. Cost is determined using the average cost method. Returned goods included in Inventory are valued at estimated realizable value, but not in excess of cost. For more information, see Note 7. Videogame development costs are expensed as incurred before the applicable videogames reach technological feasibility. Upon release, the capitalized videogame development costs are amortized based on the greater of the amount computed using (i) the proportion of the videogame’s revenues recognized for such period to the videogame’s total current and anticipated revenues or (ii) the straight-line method over the remaining economic life of the videogame. Unamortized capitalized videogame production and development costs are stated at the lower of cost, less accumulated amortization, or net realizable value and reported in Other assets on the Consolidated Balance Sheet. At December 31, 2016 and 2015 , there were $247 million and $201 million , respectively, of unamortized computer software costs related to videogames. Amortization of such costs was $101 million , $214 million and $115 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Included in such amortization are writedowns to net realizable value of certain videogame production costs of $20 million , $17 million and $51 million in 2016 , 2015 and 2014 , respectively.
Accounting for Collaborative Arrangements	Accounting for Collaborative Arrangements The Company’s collaborative arrangements primarily relate to co-financing arrangements to jointly finance and distribute theatrical productions and an arrangement entered into with CBS Broadcasting, Inc. (“CBS”) and the NCAA that provides Turner and CBS with exclusive television, Internet and wireless rights to the NCAA Tournament in the U.S. and its territories and possessions from 2011 through 2032. In most cases, the form of the co-financing arrangement is the sale of an interest in a film to an investor. Warner Bros. generally records the amounts received for the sale of an interest as a reduction of the costs of the film, as the investor assumes full risk for that share of the film asset acquired in these transactions. The substance of these arrangements is that the third-party investors own an interest in the film and, therefore, in each period the Company reflects in the Consolidated Statement of Operations either a charge or benefit to Costs of revenues to reflect the estimate of the third-party investor’s interest in the profits or losses incurred on the film. The estimate of the third-party investor’s interest in profits or losses incurred on the film is determined using the film forecast computation method. For the years ended December 31, 2016 , 2015 and 2014 , net participation costs related to third party investors of $249 million , $406 million and $580 million , respectively, were recorded in Costs of revenues. The aggregate programming rights fee, production costs, advertising revenues and sponsorship revenues related to the NCAA Tournament and related programming are equally shared by Turner and CBS. However, if the amount paid for the programming rights fee and production costs in any given year exceeds advertising and sponsorship revenues for that year, CBS’ share of such shortfall is limited to specified annual amounts (the “loss cap”), ranging from approximately $30 million to $45 million . The amounts incurred by the Company pursuant to the loss cap during the years ended December 31, 2016 and 2015 were not significant. In accounting for this arrangement, the Company records Advertising revenues for the advertisements aired on Turner’s networks and amortizes Turner’s share of the programming rights fee based on the ratio of current period advertising revenues to its estimate of total advertising revenues over the term of the arrangement.
Advertising Costs	Advertising Costs Time Warner expenses advertising costs as they are incurred, which generally is when the advertising is exhibited or aired. Advertising expense to third parties was $2.386 billion in 2016 , $2.586 billion in 2015 and $2.430 billion in 2014 .
Income Taxes	Income Taxes Income taxes are provided using the asset and liability method, such that income taxes (i.e., deferred tax assets, deferred tax liabilities, taxes currently payable/refunds receivable and tax expense) are recorded based on amounts refundable or payable in the current year and include the results of any difference between GAAP and tax reporting. Deferred income taxes reflect the tax effect of net operating losses, capital losses and tax credit carryforwards and the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial statement and income tax purposes, as determined under tax laws and rates. Valuation allowances are established when management determines that it is more likely than not that some portion or all of the deferred tax asset will not be realized. The financial effect of changes in tax laws or rates is accounted for in the period of enactment. The subsequent realization of net operating loss and general business credit carryforwards acquired in acquisitions accounted for using the purchase method of accounting is recognized in the Consolidated Statement of Operations. Tax credits received for the production of a film or program are offset against the cost of inventory capitalized. Deferred tax assets are included in Other assets in the Consolidated Balance Sheet. From time to time, the Company engages in transactions in which the tax consequences may be subject to uncertainty. Examples of such transactions include business acquisitions and dispositions, including dispositions designed to be tax free, and certain financing transactions. Significant judgment is required in assessing and estimating the tax consequences of these transactions. The Company prepares and files tax returns based on its interpretation of tax laws and regulations. In the normal course of business, the Company’s tax returns are subject to examination by various taxing authorities. Such examinations may result in future tax and interest assessments by these taxing authorities. In determining the Company’s tax provision for financial reporting purposes, the Company establishes a reserve for uncertain tax positions unless such positions are determined to be more likely than not of being sustained upon examination based on their technical merits. There is considerable judgment involved in determining whether positions taken on the Company’s tax returns are more likely than not of being sustained. The Company adjusts its tax reserve estimates periodically because of ongoing examinations by, and settlements with, the various taxing authorities, as well as changes in tax laws, regulations and interpretations. The Company’s policy is to recognize, when applicable, interest and penalties on uncertain tax positions as part of income tax expense. For further information, see Note 10.
Discontinued Operations	Discontinued Operations In determining whether a group of assets disposed (or to be disposed) of should be presented as a discontinued operation, the Company assesses whether the disposal (or planned disposal) represents a strategic shift that has had or will have a major effect on the Company’s operations and financial results. On June 6, 2014 (the “Distribution Date”), the Company completed the legal and structural separation of the Company's Time Inc. segment from the Company (the “Time Separation”). The Company has presented the financial position and results of operations of its former Time Inc. segment as discontinued operations in the accompanying consolidated financial statements for all periods presented. For more information on the Time Separation, see Note 4.
Derivatives, Offsetting Fair Value Amounts	For such foreign exchange contracts, the Company offsets the fair values of the amounts owed to or due from the same counterparty and classifies the net amount as a net asset or net liability within Prepaid expenses and other current assets or Accounts payable and accrued liabilities, respectively, in the Consolidated Balance Sheet.
Income Tax Uncertainties	The Company’s policy is to recognize interest and penalties accrued on uncertain tax positions as part of income tax expense. The Company recognizes income tax benefits for tax positions determined more likely than not to be sustained upon examination, based on the technical merits of the positions.
