Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description Of Business And Basis Of Presentation	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Description of Business Discovery Communications, Inc. (“Discovery” or the “Company”) is a global media company that provides content across multiple distribution platforms, including pay-TV, free-to-air ("FTA") and broadcast television networks, websites, digital distribution arrangements and content licensing agreements. The Company also develops and sells curriculum-based education products and services and operates production studios. The Company classifies its operations in two reportable segments: U.S. Networks, consisting principally of domestic television networks and websites, and International Networks, consisting principally of international television networks and websites; and two combined operating segments referred to as Education and Other, consisting principally of curriculum-based product and service offerings and production studios. Financial information for Discovery’s reportable segments is discussed in Note 16. Basis of Presentation The consolidated financial statements include the accounts of Discovery and its majority-owned subsidiaries in which a controlling interest is maintained. For each non-wholly owned subsidiary, the Company evaluates its ownership and other interests to determine whether it should consolidate the entity or account for its ownership interest as an investment. As part of its evaluation, the Company makes judgments in determining whether the entity is a variable interest entity ("VIE") and, if so, whether it is the primary beneficiary of the VIE and is thus required to consolidate the entity. (See Note 3.) Inter-company accounts and transactions between consolidated entities have been eliminated in consolidation. Unaudited Interim Financial Statements These consolidated financial statements are unaudited; however, in the opinion of management, they reflect all adjustments consisting only of normal recurring adjustments necessary to state fairly the financial position, results of operations and cash flows for the periods presented in conformity with U.S. generally accepted accounting principles (“GAAP”) applicable to interim periods. The results of operations for the interim periods presented are not necessarily indicative of results for the full year or future periods. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in Discovery’s Annual Report on Form 10-K for the year-ended December 31, 2015 (the “ 2015 Form 10-K”). Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates, judgments and assumptions that affect the amounts and disclosures reported in the consolidated financial statements and accompanying notes. Management continually re-evaluates its estimates, judgments and assumptions, and management’s evaluation could change. These estimates are sometimes complex, sensitive to changes in assumptions and require fair value determinations using Level 3 fair value measurements. Actual results may differ materially from those estimates. Estimates inherent in the preparation of the consolidated financial statements include accounting for asset impairments, revenue recognition, allowances for doubtful accounts, content rights, depreciation and amortization, business combinations, equity-based compensation, income taxes, other financial instruments, contingencies and the determination of whether the Company is the primary beneficiary of entities in which it holds variable interests. Accounting and Reporting Pronouncements Adopted Business Consolidation In February 2015, the Financial Accounting Standards Board ("FASB") issued guidance that amends the analysis that a reporting entity performs to determine whether it should consolidate certain legal entities. The changes in this guidance include how related parties and de facto agents are considered in the primary beneficiary determination and the analysis for determining whether a fee paid to a decision maker or service provider is a variable interest. The new standard is effective for reporting periods beginning after December 15, 2015 and can be adopted either retrospectively or using a modified retrospective approach by recording a cumulative-effect adjustment to stockholders' equity as of the beginning of the fiscal year of adoption. The Company adopted this guidance effective January 1, 2016, and there was no effect on the consolidated financial statements. Business Combinations In September 2015, the FASB issued new guidance on adjustments to provisional amounts recognized in a business combination, which are currently recognized on a retrospective basis. Under the new requirements, adjustments will be recognized in the reporting period in which the adjustments are determined. The effects of changes in depreciation, amortization, or other income arising from changes to the provisional amounts, if any, are included in earnings of the reporting period in which the adjustments to the provisional amounts are determined. An entity is also required to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The Company adopted this guidance effective January 1, 2016, and there was no effect on the consolidated financial statements. Accounting for Fees Paid in a Cloud Computing Arrangement In April 2015, the FASB issued explicit guidance on the recognition of fees paid by a customer for cloud computing arrangements as either the acquisition of a software license or a service contract. The Company adopted this guidance effective October 1, 2015, and there was no material effect on the consolidated financial statements. Presentation of Debt Issuance Costs In April 2015, the FASB issued guidance requiring all debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the debt instead of being presented as an asset on the balance sheet. The Company retrospectively adopted the new guidance effective April 1, 2015 and reclassified its unamortized debt issuance costs related to the Company's debt from other noncurrent assets to noncurrent portion of debt on the consolidated balance sheet as of December 31, 2014. Accounting and Reporting Pronouncements Not Yet Adopted Share-Based Payment In March 2016, the FASB issued guidance that simplifies how share-based payments are accounted for and presented in the financial statements. The new guidance includes requirements to record all of the tax effects related to share-based payments at settlement through the income statement, allows for tax withholdings up to maximum statutory rates before precluding equity accounting, and allows the Company to make an accounting policy election for the impact of forfeitures on the recognition of expense. The new standard is effective for reporting periods beginning after December 15, 2016 and can be adopted early in any interim period, with any adjustments reflected as of the beginning of the fiscal year of adoption in retained earnings. The Company is currently evaluating the impact that the pronouncement will have on the consolidated financial statements. Leases In February 2016, the FASB issued guidance on leases that will require lessees to recognize almost all of their leases on the balance sheet by recording a right-of-use asset and liability. The new standard will be effective for reporting periods beginning after December 15, 2018, and requires application of the new accounting guidance at the beginning of the earliest comparative period presented in the year of adoption. The Company is currently evaluating the impact that the pronouncement will have on the consolidated financial statements. Recognition and Measurement of Financial Instruments In January 2016, the FASB issued guidance regarding the classification and measurement of financial instruments, which significantly revises the classification and measurement of investments in equity securities. This standard requires equity securities to be measured at fair value with changes in the fair value recognized through net income, and supersedes the guidance permitting entities to record gains and losses on equity securities with readily determinable fair values in accumulated other comprehensive income. Investments accounted for under the equity method of accounting or that result in consolidation are not included within the scope of this update. The new standard will be effective for reporting periods beginning after December 15, 2017. This pronouncement is expected to impact the Company's accounting for changes in the fair value of available-for-sale ("AFS") securities. Balance Sheet Classification of Deferred Taxes In November 2015, the FASB issued guidance to simplify the presentation of deferred income taxes, which removes the requirement to separate deferred tax liabilities and assets into current and noncurrent amounts and instead requires all such amounts be classified as noncurrent on the Company's consolidated balance sheets. The new requirement will be effective for financial statements issued for annual periods beginning after December 15, 2016, and can be adopted on either a retrospective or prospective basis. The Company is currently evaluating the impact that the pronouncement will have on the consolidated financial statements. Presentation of Financial Statements - Going Concern In August 2014, the FASB issued guidance requiring the Company to perform interim and annual assessments regarding conditions or events that raise substantial doubt about the Company's ability to continue as a going concern and to provide related disclosures, if applicable. The new standard is effective for reporting periods ending after December 15, 2016, with early adoption permitted. The adoption of this standard is not expected to have a material effect on the consolidated financial statements. Revenue from Contracts with Customers In May 2014, the FASB issued an accounting pronouncement related to revenue recognition, which applies a single, comprehensive revenue recognition model for all contracts with customers. This standard, as amended, contains principles with respect to the measurement and timing of recognition of revenue. The Company will recognize revenue to reflect the transfer of goods or services to customers at an amount that it expects to be entitled to receive in exchange for those goods or services. The new standard is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. The Company is required to apply the new revenue standard beginning in the first interim period within the year of adoption. The Company is currently evaluating the impact that the pronouncement will have on the consolidated financial statements. Concentrations Risk Customers The Company has long-term contracts with distributors around the world. For the U.S. Networks segment, more than 90% of distribution revenue comes from the Company's top 10 distributors in the U.S. For the International Networks segment, approximately 45% of distribution revenue comes from the Company's top 10 distributors outside of the U.S. Agreements in place with the major cable and satellite operators in the U.S. expire at various times in 2016 through 2021 . One of the Company's top 10 U.S. distribution agreements has been extended under a short-term agreement. Although the Company seeks to renew its agreements with its distributors prior to expiration of a contract, a delay in securing a renewal that results in a service disruption, a failure to secure a renewal or a renewal on less favorable terms may have a material adverse effect on the Company’s financial condition and results of operations. Not only could the Company experience a reduction in distribution revenue, but it could also experience a reduction in advertising revenue, as viewership is impacted by affiliate subscriber levels. No individual customer accounted for more than 10% of total consolidated revenues for the three and six months ended June 30, 2016 or 2015 . As of June 30, 2016 and December 31, 2015 , the Company’s trade receivables did not represent a significant concentration of credit risk as the customers and markets in which the Company operates are varied and dispersed across many geographic areas. Financial Institutions Cash and cash equivalents are maintained with several financial institutions. The Company has deposits held with banks that exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputable credit and, therefore, bear minimal credit risk. Additionally, the Company has cash and cash equivalents held by its foreign subsidiaries that would result in U.S. tax consequences should the Company decide it needs to repatriate these funds to the U.S. Lender Counterparties There is a risk that the counterparties associated with the Company’s revolving credit facility will not be available to fund as obligated under the terms of the facility and that the Company may, at the time of such unavailability to fund, have limited or no access to the commercial paper market. If funding under the revolving credit facility is unavailable, the Company may have to acquire a replacement credit facility from different counterparties at a higher cost or may be unable to find a suitable replacement. Typically, the Company seeks to manage such risks from its revolving credit facility by contracting with experienced large financial institutions and monitoring the credit quality of its lenders. As of June 30, 2016 , the Company did not anticipate nonperformance by any of its counterparties.

Business Combinations [Abstract]
Acquisitions And Dispositions	ACQUISITIONS AND DISPOSITIONS Acquisitions Eurosport France On December 21, 2012, the Company acquired a 20% equity method investment in Eurosport France. On March 31, 2015 , the Company acquired an additional 31% interest in Eurosport France for €36 million ( $38 million ). This transaction gave the Company a 51% controlling stake in Eurosport France. The Company recognized a gain of $2 million during the six months ended June 30, 2015, to account for the difference between the carrying value and the fair value of the previously held 20% equity method investment in Eurosport France as a component of other income (expense), net in the Company's consolidated statements of operations. (See Note 13.) On October 1, 2015 , the Company acquired the remaining 49% of Eurosport France. (See Note 8.) Eurosport France is part of Eurosport, a leading pan-European sports media platform. The flagship Eurosport network focuses on regionally popular sports, such as tennis, skiing, cycling and motor sports. Eurosport’s brands and platforms also include Eurosport HD (high definition simulcast), Eurosport 2, Eurosport 2 HD (high definition simulcast) and Eurosportnews. The acquisition is intended to increase the growth of Eurosport and enhance the Company's pay-TV offerings in Europe. The Company used a discounted cash flow ("DCF") analysis, which represents a Level 3 fair value measurement, to assess certain components of the Eurosport France purchase price allocation. The fair value of the assets acquired, liabilities assumed, noncontrolling interest recognized and the remeasurement gain recorded on the previously held equity interest is presented in the table below (in millions). March 31, 2015 Goodwill $ 69 Intangible assets 40 Other assets acquired 25 Cash 35 Removal of TF1 put right 2 Currency translation adjustment (6 ) Remeasurement gain on previously held equity interest (2 ) Liabilities assumed (30 ) Deferred tax liabilities (14 ) Redeemable noncontrolling interest (Note 8) (60 ) Carrying value of previously held equity interest (21 ) Net assets acquired $ 38 The goodwill reflects the workforce and synergies expected from increased pan-European market penetration as the operations of Eurosport and the Company are combined. The goodwill recorded as part of this acquisition is included in the International Networks reportable segment and is not amortizable for tax purposes. Intangible assets primarily consist of distribution and advertising customer relationships, advertiser backlog and trademarks with a weighted average estimated useful life of 10 years . Other In 2015, the Company acquired several other unrelated businesses for total cash and contingent consideration of $91 million , net of cash acquired. Total consideration, net of cash acquired, included contingent consideration of $13 million as of December 31, 2015 , of which $1 million was paid during the six months ended June 30, 2016 . The Company recorded $54 million and $43 million of goodwill and intangible assets, respectively, in connection with these acquisitions. The acquisitions included FTA networks in Italy and Turkey, cable networks in Denmark and a pay-TV sports channel in Asia. The goodwill reflects the synergies and regional market penetration from combining the operations of these acquisitions with the Company's operations. Impact of Business Combinations The operations of each of the business combinations in 2015 discussed above were included in the consolidated financial statements as of each of their respective acquisition dates. The following table presents their revenue and earnings as reported within the consolidated financial statements for the current period (in millions). Three months ended June 30, 2016 Six months ended June 30, 2016 Revenues: Distribution $ 22 $ 43 Advertising 17 30 Other 1 2 Total revenues $ 40 $ 75 Net income $ 8 $ 15 Three months ended June 30, 2015 Six months ended June 30, 2015 Revenues: Distribution $ 18 $ 18 Advertising 2 3 Other — — Total revenues $ 20 $ 21 Net income $ — $ — Dispositions Russia On October 7, 2015 , Discovery recorded a loss of $5 million upon deconsolidation of its Russian business following its contribution to a joint venture (the “New Russian Business”) with a Russian media company, National Media Group ("NMG"). The New Russian Business was established to comply with changes in Russian legislation that limit foreign ownership of media companies in Russia. No cash consideration was exchanged in the transaction. NMG contributed an FTA license which enables advertising for the New Russian Business. As part of the transaction, Discovery obtained a 20% ownership interest in the New Russian Business, which is accounted for under the equity method of accounting. The loss on contribution of the Russian business included $15 million of goodwill allocated to the transaction based on the relative fair values of the Russian business disposed of and the portion of the reporting unit that was retained. Although Discovery no longer consolidates the Russian business, Discovery earns revenue by providing content and brands to the New Russian Business under long-term licensing arrangements. The Russian business was included in the International Networks reportable segment; the licensing arrangements are reported as distribution revenue in the International Networks reportable segment. (See Note 14 and Note 16.) Radio On June 30, 2015 , Discovery sold its radio business in Northern Europe to Bauer Media Group ("Bauer") for total consideration, net of cash disposed, of €72 million ( $80 million ), which included €54 million ( $61 million ) in cash and €18 million ( $19 million ) of contingent consideration. The cumulative gain on the disposal is $1 million and includes $26 million of goodwill allocated to the transaction based on the relative fair values of the radio business disposed of and the portion of the reporting unit that was retained. Upon sale, the Company recorded a $3 million gain including estimated contingent consideration as disclosed for the three and six months ended June 30, 2015 . For the year-end December 31, 2015 , the Company revised its estimated contingent consideration resulting in a $12 million loss. Based on the final resolution and receipt of contingent consideration payable, Discovery recorded a pre-tax gain of $13 million for the six months ended June 30, 2016 . The Company determined that the disposal did not meet the definition of a discontinued operation because it does not represent a strategic shift that has a significant impact on the Company's operations and consolidated financial results. The Company's radio business had no impact to income before income taxes for the six months ended June 30, 2015 . The Company's radio businesses were part of the International Networks reportable segment.

Investments [Abstract]
Investments	INVESTMENTS The Company’s investments consisted of the following (in millions). Category Balance Sheet Location June 30, 2016 December 31, 2015 Trading securities: Mutual funds Prepaid expenses and other current assets $ 154 $ 149 Equity method investments Equity method investments 535 567 Available-for-sale securities: Common stock Other noncurrent assets 51 81 Common stock - pledged Other noncurrent assets 51 81 Cost method investments Other noncurrent assets 48 43 Total investments $ 839 $ 921 Trading Securities Trading securities include investments in mutual funds held in a separate trust which are owned as part of the Company’s supplemental retirement plan. (See Note 4.) Equity Method Investments In the normal course of business, the Company makes investments that support its underlying business strategy and enable it to enter new markets and develop programming. All equity method investees are privately owned. The carrying values of the Company’s equity method investments are consistent with its ownership in the underlying net assets of the investees, except for Oprah Winfrey Network ("OWN"), because the Company has recorded losses in excess of its ownership interest. Certain of the Company's equity method investments are VIEs, for which the Company is not the primary beneficiary. As of June 30, 2016 , the Company’s estimated risk of loss for all its VIEs including the investment carrying values, unfunded contractual commitments, and guarantees made on behalf of VIEs was approximately $390 million . The Company's estimated risk of loss excludes the non-contractual future funding of VIEs. The aggregate carrying values of these VIE investments were $384 million and $423 million as of June 30, 2016 and December 31, 2015 , respectively. The Company recognized its portion of net losses by VIE's of $5 million and $3 million for the three months ended June 30, 2016 and 2015 , respectively, and net income generated by VIE's of $4 million and $10 million for the six months ended June 30, 2016 and 2015 , respectively. OWN OWN is a pay-TV network and website that provides adult lifestyle content, which is focused on self-discovery, self-improvement and entertainment. Since the initial equity was not sufficient to fund OWN's activities without additional subordinated financial support in the form of a note receivable held by the Company, OWN is a VIE. While the Company and Harpo, Inc. ("Harpo") are partners who share equally in voting control, power is not shared because Harpo holds operational rights related to programming and marketing, as well as selection and retention of key management personnel, that significantly impact OWN’s economic performance. Accordingly, the Company has determined that it is not the primary beneficiary of OWN and accounts for its investment in OWN using the equity method. However, the Company provides OWN content licenses and services, such as distribution, sales and administrative support, for a fee and has provided OWN funding. (See Note 14.) The carrying value of the Company’s investment in OWN of $336 million and $373 million as of June 30, 2016 and December 31, 2015 , respectively, includes the Company's note receivable and accumulated investment losses. The Company's combined advances to and note receivable from OWN, including accrued interest, were $348 million and $384 million as of June 30, 2016 and December 31, 2015 , respectively. On April 30, 2015, Oprah Winfrey agreed to extend her exclusivity agreement with OWN and the note receivable agreement was modified to reduce its interest rate, compounded annually, from 7.5% to 5.0% , retroactive to January 1, 2014. During the six months ended June 30, 2016 , the Company received net repayments of $45 million from OWN and accrued interest on the note receivable of $9 million . The note receivable is secured by the net assets of OWN. While the Company has no further funding commitments, the Company will provide additional funding to OWN, if necessary, and expects to recoup amounts funded. There can be no event of default on the borrowing until 2023. However, borrowings are scheduled for repayment four years after the borrowing date to the extent that OWN has excess cash to repay the borrowings then due. Following such repayment, OWN’s subsequent cash distributions will be shared equally between the Company and Harpo. In accordance with the venture agreement, losses generated by OWN are generally allocated to both investors based on their proportionate ownership interests. However, the Company has recorded its portion of OWN’s losses based upon accounting rules for equity method investments. Prior to the contribution of the Discovery Health network to OWN at its launch, the Company had recognized $104 million , or 100% , of OWN’s net losses. During the three months ended March 31, 2012, accumulated operating losses at OWN exceeded the equity contributed to OWN, and Discovery began again to record 100% of OWN’s net losses. Although OWN has become profitable, the Company will record 100% of any net losses to the extent they occur resulting from OWN's operations as long as Discovery has provided all funding to OWN and OWN’s accumulated losses continue to exceed the equity contributed. All of OWN's net income has been and will continue to be recorded by the Company until the Company recovers losses absorbed in excess of the Company's equity ownership interest. The Company monitors the financial results of OWN along with other relevant business information to assess the recoverability of the OWN note receivable. There has been no impairment of the OWN note receivable. Based on the joint venture agreement, as amended on April 1, 2016, Harpo has the right to conditionally require the Company to purchase all or part of Harpo’s interest in OWN at fair market value up to a maximum put amount during 90-day windows beginning on April 1, 2017 and every two and a half years commencing July 1, 2018 through January 1, 2026. The maximum put amount ranges from $100 million on the first put exercise date up to a cumulative cap of $400 million on the fifth put exercise date. The Company has not recorded amounts for the put right because the fair value of this put right was zero as of June 30, 2016 and December 31, 2015 . Other Equity Method Investments At June 30, 2016 and December 31, 2015, the Company's other equity method investments included the New Russian Business, All3Media and certain joint ventures in Canada. In addition on June 24, 2016, the Company acquired a 27.5% interest in Mega TV, a FTA channel in Chile owned by Bethia Comunicaciones, for $53 million . Available-for-Sale Securities On November 12, 2015, the Company acquired 5 million shares, or approximately 3% , of Lions Gate Entertainment Corp. ("Lionsgate"), an entertainment company, for $195 million . As the shares have a readily determinable fair value and the Company has the intent to retain the investment, the shares are classified as AFS securities. The components of the Company's AFS securities, which are included in other non-current assets, are summarized in the table below (in millions). June 30, 2016 December 31, 2015 Cost $ 195 $ 195 Unrealized losses (93 ) (33 ) Fair Market Value $ 102 $ 162 Unrealized losses related to our investment in Lionsgate shares represent 48% of our cost. If declines in the value of AFS securities are determined to be other-than-temporary, any loss is recorded in earnings in the period identified as a component of other income (expense), net on the consolidated statements of operations. Impairments are determined based on, among other factors, the length of time the fair value of the investment has been less than the carrying value, future business prospects for the investee, and information regarding market and industry trends for the investee’s business, if available. Lionsgate share prices have historically been volatile. The Company continues to believe in the long-term value of the investment and does not intend to dispose of its Lionsgate shares for the foreseeable future. Based on current information, the Company anticipates that the fair value of its investment in Lionsgate will recover. Accordingly, the Company concluded that there were no unrealized losses that were other-than-temporary as of June 30, 2016 . However, the Company continues to carefully monitor this investment. In connection with the investment in Lionsgate, the Company hedged 50% of the shares with an equity collar (the “Lionsgate Collar”) and pledged those shares as collateral to the derivative counter party. In the application of hedge accounting, when the share price of Lionsgate is within the boundaries of the collar and the hedge has no intrinsic value, the Company records the gains or losses on the Lionsgate AFS securities as a component of other comprehensive (loss) income. When the share price of the Lionsgate AFS is outside the boundaries of the collar and the hedge has intrinsic value, the Company records a gain or loss for the change in the fair value of the hedged portion of Lionsgate shares that correspond to the change in intrinsic value of the hedge as a component of other income (expense), net. For the three and six months ended June 30, 2016 , the Company recorded temporary unrealized losses of $8 million and $60 million , respectively, related to this investment, of which $4 million and $30 million , respectively, were recorded as a component of other comprehensive (loss) income and $4 million and $30 million , respectively, were recorded as a component of other income (expense), net. (See Note 7.) Cost Method Investments Cost method investments include ownership rights in entities that do not provide the Company with control or significant influence in these investments and that have no readily determinable fair values. The Company's cost method investments as of June 30, 2016 primarily include an educational website and an electric car racing series.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants. Assets and liabilities carried at fair value are classified in the following three categories: Level 1 – Quoted prices for identical instruments in active markets. Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 3 – Valuations derived from techniques in which one or more significant inputs are unobservable. The tables below present assets and liabilities measured at fair value on a recurring basis (in millions). June 30, 2016 Category Balance Sheet Location Level 1 Level 2 Level 3 Total Assets Trading securities - mutual funds Prepaid expenses and other current assets $ 154 $ — $ — $ 154 Available-for-sale securities: Common stock Other noncurrent assets 51 — — 51 Common stock - pledged Other noncurrent assets 51 — — 51 Derivatives: Cash flow hedges: Foreign exchange Prepaid expenses and other current assets — 33 — 33 Foreign exchange Other noncurrent assets — 5 — 5 Fair value hedges: Equity (Lionsgate Collar) Other noncurrent assets — 37 — 37 Net investment hedges: Cross-currency swaps Other noncurrent assets — 21 — 21 Total $ 256 $ 96 $ — $ 352 Liabilities Deferred compensation plan Accrued liabilities $ 154 $ — $ — $ 154 Derivatives: Cash flow hedges: Foreign exchange Accrued liabilities — 36 — 36 Foreign exchange Other noncurrent liabilities — 6 — 6 Net investment hedges: Cross-currency swaps Other noncurrent liabilities — 29 — 29 Total $ 154 $ 71 $ — $ 225 December 31, 2015 Category Balance Sheet Location Level 1 Level 2 Level 3 Total Assets Trading securities - mutual funds Prepaid expenses and other current assets $ 149 $ — $ — $ 149 Available-for-sale securities: Common stock Other noncurrent assets 81 — — 81 Common stock - pledged Other noncurrent assets 81 — — 81 Derivatives: Cash flow hedges: Foreign exchange Prepaid expenses and other current assets — 21 — 21 Foreign exchange Other noncurrent assets — 2 — 2 Fair value hedges: Equity (Lionsgate Collar) Other noncurrent assets — 15 — 15 Total $ 311 $ 38 $ — $ 349 Liabilities Deferred compensation plan Accrued liabilities $ 149 $ — $ — $ 149 Derivatives: Foreign exchange Accrued liabilities — 4 — 4 Total $ 149 $ 4 $ — $ 153 Trading securities are comprised of investments in mutual funds held in a separate trust which are owned as part of the Company’s deferred compensation plan. The fair value of Level 1 trading securities was determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. The fair value of the deferred compensation plan liability was determined based on the fair value of the related investments elected by employees. AFS securities represent equity investments with readily determinable fair values. The fair value of Level 1 AFS securities was determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. (See Note 3). Derivative financial instruments are comprised of net investment hedges and foreign exchange and equity contracts used by the Company to modify its exposure to market risks from foreign exchange rates and changes in the fair value of AFS securities. Periodically, interest rate contracts are used to modify exposure to market risks from the pricing of forecasted issuances of debt. The fair value of Level 2 derivative financial instruments was determined using a market-based approach. In addition to the financial instruments listed in the tables above, the Company holds other financial instruments, including cash deposits, accounts receivable, accounts payable, commercial paper, borrowings under the revolving credit facility, capital leases and senior notes. The carrying values for such financial instruments, other than the senior notes, each approximated their fair values as of June 30, 2016 . The estimated fair value of the Company’s outstanding senior notes using quoted prices from over the counter markets, considered Level 2 inputs, was $7.5 billion and $6.6 billion as of June 30, 2016 and December 31, 2015 , respectively.

The proceeds received by DCL from the offering were net of a $2 million issuance discount and $3 million of debt issuance costs. Interest on the 2016 USD Notes is payable semi-annually on March 11 and September 11 of each year. Revolving Credit Facility On February 4, 2016, DCL amended its $1.5 billion revolving credit facility to allow DCL and certain designated foreign subsidiaries of DCL to borrow up to $2.0 billion , including a $100 million sublimit for the issuance of standby letters of credit and a $50 million sublimit for swingline loans. Borrowing capacity under this agreement is reduced by any outstanding borrowings under the commercial paper program discussed below. The revolving credit facility agreement provides for a maturity date of February 4, 2021 and the option for up to two additional 364-day renewal periods. As of June 30, 2016 , the Company had outstanding borrowings under the revolving credit facility of $480 million at a weighted average interest rate of 2.00% , none of which was denominated in foreign currencies. As of December 31, 2015 , the Company had outstanding borrowings under the revolving credit facility of $782 million at a weighted average interest rate of 1.55% of which $207 million was denominated in foreign currencies. The interest rate on borrowings under the revolving credit facility is variable based on DCL's then-current credit ratings for its publicly traded debt and changes in financial index rates. For dollar-denominated borrowings, the interest rate is based, at the Company's option, on either adjusted LIBOR plus a margin, or an alternate base rate plus a margin. For borrowings denominated in foreign currencies, the interest rate is based on adjusted LIBOR, plus a margin. The current margins are 1.30% and 0.30% , respectively, per annum for adjusted LIBOR and alternate base rate borrowings. A monthly facility fee is charged based on the total capacity of the facility, and interest is charged based on the amount borrowed on the facility. The current facility fee rate is 0.20% per annum and subject to change based on DCL's then-current credit ratings. All obligations of DCL and the other borrowers under the revolving credit facility are unsecured and are fully and unconditionally guaranteed by Discovery. The credit agreement governing the revolving credit facility contains customary representations, warranties and events of default, as well as affirmative and negative covenants. As of June 30, 2016 , the Company, DCL and the other borrowers were in compliance with all covenants, and there were no events of default under the revolving credit facility. Commercial Paper The Company's commercial paper program is supported by the revolving credit facility described above. Outstanding commercial paper borrowings were $106 million with a weighted average interest rate of approximately .95% as of June 30, 2016 and $93 million with a weighted average interest rate of approximately 1.10% as of December 31, 2015 .

Derivative Financial Instrument

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS The Company uses derivative financial instruments to modify its exposure to market risks from changes in foreign currency exchange rates, interest rates and the fair value of investments classified as AFS securities. Derivative financial instruments that qualify for hedge accounting have been designated as cash flow hedges, net investment hedges and fair value hedges as applicable. The Company does not enter into or hold derivative financial instruments for speculative trading purposes. Cash Flow Hedges The Company designates foreign currency forward and option contracts as cash flow hedges to mitigate foreign currency risk arising from third-party revenue and inter-company licensing agreements. The Company also designates interest rate contracts used to hedge the pricing for certain senior notes as cash flow hedges. Gains and losses on the effective portion of designated cash flow hedges are initially recorded in accumulated other comprehensive loss on the consolidated balance sheets and reclassified into the statements of operations in the same line item in which the hedged item is recorded and in the same period as the hedged item affects earnings. If it becomes probable that a forecasted transaction will not occur, any related gains and losses recorded in accumulated other comprehensive loss on the consolidated balance sheets are reclassified to other income (expense), net on the consolidated statements of operations in that period. During the three months ended March 31, 2015, the Company terminated and settled its interest rate cash flow hedges following the pricing of its 3.45% senior notes due March 15, 2025 (the "2015 USD Notes"). The total notional value of the interest rate forward contracts at the termination date was $490 million , which exceeded the $300 million principal amount of the 2015 USD Notes. Of the $40 million pretax loss recorded in accumulated other comprehensive loss at the termination date, $29 million was an effective cash flow hedge that will be amortized as an adjustment to interest expense over the ten year term of the 2015 USD Notes consistent with amortization of the debt discount. The remaining $11 million was reclassified into other income (expense), net on the consolidated statements of operations during the three months ended March 31, 2015, because the forecasted borrowing transaction was no longer probable. Net Investment Hedges On April 7, 2016, the Company entered into a series of euro and British pound cross-currency swaps. Changes in the fair value of these cross-currency swaps, designated as hedges of net investments in foreign operations, are reported in the same manner as translation adjustments to the extent that they are effective. Changes in the value of the investment due to changes in spot rates are offset by fair value changes in the effective portion of the derivative instrument. Both changes are recorded as cumulative translation adjustments, a component of accumulated other comprehensive loss , and are only recognized in earnings upon the liquidation or sale of the hedged investment. If the notional amount of the instrument designated as the hedge of a net investment is greater than the portion of the net investment being hedged, hedge ineffectiveness, which is the gain or loss of the portion over hedged, is reclassified to other income (expense), net on the consolidated statements of operations in that period. Fair Value Hedges The Company designates derivative instruments used to mitigate the risk of changes in the fair value of its AFS securities as fair value hedges. On November 12, 2015, the Company entered into the Lionsgate Collar, designed to mitigate the risk of market fluctuations with respect to 50% of the Lionsgate shares held by the Company. (See Note 3.) The collar, which qualifies for hedge accounting, settles in three tranches starting in 2019 and ending in 2022. The Company records gains and losses from the Lionsgate Collar as a component of other income (expense), net on the consolidated statement of operations. No Hedging Designation The Company may also enter into derivative financial instruments that do not qualify for hedge accounting and are not designated as hedges. These instruments are intended to mitigate economic exposures of the Company. Realized and unrealized gains and losses on instruments that do not qualify for hedge accounting are reflected in other income (expense), net on the consolidated statements of operations. The pre-tax impact of derivatives not designated as hedges was a loss of $2 million for the three and six months ended June 30, 2016 . The Company records all unsettled derivative contracts at their gross fair values on the consolidated balance sheets. (See Note 4.) There were no amounts eligible to be offset under master netting agreements as of June 30, 2016 and December 31, 2015 . The cash flows from the effective portion of derivative instruments used as hedges are classified in the consolidated statements of cash flows in the same section as the cash flows from the hedged item. For example, the cash paid or received to settle the effective portion of foreign exchange derivatives intended to hedge distribution revenue earned during the six months ended June 30, 2016 is reported as an operating activity in the consolidated statements of cash flows consistent with the classification of cash received from customers. The cash flows from the ineffective portion of derivative instruments used as hedges and derivative contracts not designated as hedges are reported as investing activities in the consolidated statements of cash flows.

Noncontrolling Interest [Abstract]
Redeemable Noncontrolling Interests	REDEEMABLE NONCONTROLLING INTERESTS Redeemable noncontrolling interests reflected as of the balance sheet date are the greater of the noncontrolling interest balances adjusted for comprehensive income items and distributions or the redemption values remeasured at the period end foreign exchange rates (i.e., the "floor"). Adjustments to the carrying amount of redeemable noncontrolling interests to redemption value as a result of changes in exchange rates are reflected in currency translation adjustments, a component of other comprehensive (loss) income ; however, such currency translation adjustments to redemption value are allocated to Discovery stockholders only. Redeemable noncontrolling interest adjustments of redemption value to the floor are reflected in retained earnings. Any adjustment of redemption value to the floor that reflects a redemption in excess of fair value is included as an adjustment to net income available to Discovery stockholders in the calculation of earnings per share. There were no current period adjustments to reflect a redemption in excess of fair value. (See Note 12.)

On July 22, 2015 , TF1 exercised its right to put the entirety of its remaining 49% noncontrolling interest in both Eurosport France and Eurosport International to the Company for €491 million ( $551 million as of the date redemption became mandatory, and $548 million on October 1, 2015 when the transaction closed). The difference between the carrying amount of the redeemable noncontrolling interest and its fair value at the date of exercise resulted in a €25 million ( $28 million ) adjustment to retained earnings, recognized as a component of redeemable noncontrolling interest adjustments to redemption value in the consolidated statements of equity for the period ended September 30, 2015. Upon acquisition of TF1's noncontrolling interest on October 1, 2015 , the Company adjusted the accumulated other comprehensive income balance of $61 million attributable to TF1 and allocated it to Discovery stockholders. In connection with its non-controlling interest in Discovery Family, Hasbro has the right to put the entirety of its remaining 40% non-controlling interest to the Company for one year after December 31, 2021, or in the event a Discovery performance obligation related to Discovery Family is not met. Embedded in the redeemable noncontrolling interest is also a Discovery call right that is exercisable for one year after December 31, 2021. Upon the exercise of the put or call options, the price to be paid for the redeemable noncontrolling interest is generally a function of the then-current fair market value of the redeemable noncontrolling interest, to which certain discounts and floor values may apply in specified situations depending upon the party exercising the put or call and the basis for the exercise of the put or call. As Hasbro's put right is outside the control of the Company, Hasbro's 40% noncontrolling interest is presented as redeemable noncontrolling interest outside of permanent equity on the Company's consolidated balance sheet. In connection with its non-controlling interest in Discovery Japan, Jupiter Telecommunications Co., Ltd ("J:COM") has the right to put all, but not less than all, of its 20% noncontrolling interest to Discovery at any time for cash. Through January 10, 2017, the redemption value is the January 10, 2013 fair value denominated in Japanese yen; thereafter, the redemption value is the greater of the then-current fair value or the January 10, 2013 fair value denominated in Japanese yen.

Equity [Abstract]
Equity	EQUITY Common Stock Repurchase Program Under the Company's stock repurchase program, management is authorized to purchase shares of the Company's common stock from time to time through open market purchases, privately negotiated transactions at prevailing prices, pursuant to one or more accelerated stock repurchase agreements, or other derivative arrangements as permitted by securities laws and other legal requirements, and subject to stock price, business and market conditions and other factors. Over the life of the program, authorization under the stock repurchase program has totaled $7.5 billion . As of June 30, 2016 , the Company had remaining authorization of $1.5 billion for future repurchases under the existing stock repurchase program, which will expire on October 8, 2017 . All common stock repurchases have been made through open market transactions and repurchased common stock has been recorded as treasury stock on the consolidated balance sheet. As of June 30, 2016 , the Company had repurchased over the life of the program 3 million and 134 million shares of Series A and Series C common stock, respectively, for the aggregate purchase price of $171 million and $5.8 billion , respectively. The table below presents a summary of common stock repurchases (in millions). Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Series C Common Stock: Shares repurchased 10.4 3.9 18.8 10.3 Purchase price $ 286 $ 123 $ 500 $ 323 Preferred Stock Repurchase and Conversion The Company has an agreement with Advance/Newhouse Programming Partnership (“Advance/Newhouse”) to repurchase, on a quarterly basis, a number of shares of Series C convertible preferred stock convertible into a number of shares of Series C common stock equal to 3/7 of the number of shares of Series C common stock purchased under the Company’s common stock repurchase program during the then most recently completed fiscal quarter. The price paid per preferred share is calculated as 99% of the average price paid for the Series C common shares repurchased by the Company during the applicable fiscal quarter multiplied by the Series C conversion rate. The Series C preferred stock is convertible, at the option of the holder, into two shares of Series C common stock. The Advance/Newhouse repurchases are made outside of the Company’s publicly announced common stock repurchase program. The repurchase transactions are recorded as a decrease of par value of preferred stock and retained earnings upon settlement as there is no remaining additional paid-in capital for this class of stock. The table below presents a summary of Series C convertible preferred stock repurchases (in millions). Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Series C Convertible Preferred Stock: Shares repurchased 1.8 1.4 4.7 3.1 Purchase price $ 91 $ 84 $ 250 $ 201 Based on the number of shares of Series C common stock repurchased during the three months ended June 30, 2016 , the Company expects to convert and retire 2.2 million shares of its Series C convertible preferred shares under the preferred stock conversion and repurchase arrangement for an aggregate purchase price of $121 million on or about August 4, 2016 . The expected purchase of these shares has not been recognized as a liability on the Company's consolidated balance sheet as of June 30, 2016 , due to certain termination rights held by Discovery and Advance/Newhouse in the preferred stock conversion and repurchase arrangement. In addition, on February 25, 2016, at the request of Advance/Newhouse and in accordance with the Company's Articles of Incorporation, the Company converted 292,500 shares of Advance/Newhouse Series C convertible preferred stock into 585,000 shares of Series C common stock.

Income Taxes	INCOME TAXES The Company's income tax expense was $95 million and $206 million , and the effective income tax rates were 19% and 23% , for the three and six months ended June 30, 2016 , respectively. The Company's income tax expense was $139 million and $264 million , and the effective income tax rates were 32% and 33% , for the three and six months ended June 30, 2015 , respectively. The following table reconciles the Company's effective income tax rate to the U.S. federal statutory income tax rate of 35% .

The Company is currently under limited issue examination by the IRS for its 2008 to 2011 tax years and under audit for its 2012 to 2014 consolidated federal income tax returns. The Company does not anticipate any material adjustments. With few exceptions, the Company is no longer subject to audit by any jurisdiction for years prior to 2006. Adjustments that arose as the audits for certain tax years were completed have been included in change in uncertain tax positions in the table above. During the three months ended June 30, 2016 , the Company resolved multi-year state tax positions that resulted in a reduction of reserves related to uncertain tax positions. The effect is included within the effective tax rate reconciliation as a component of changes in state and local income taxes, net of federal tax benefit. The Company's reserves for uncertain tax positions at June 30, 2016 and December 31, 2015 totaled $148 million and $173 million , respectively. It is reasonably possible that the total amount of unrecognized tax benefits related to certain of the Company's uncertain tax positions could decrease by as much as $26 million within the next twelve months as a result of ongoing audits, lapses of statutes of limitations or regulatory developments. As of June 30, 2016 and December 31, 2015 , the Company had accrued approximately $12 million and $20 million of total interest and penalties payable related to unrecognized tax benefits, respectively. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE In calculating earnings per share, the Company follows the two-class method, which distinguishes between the classes of securities based on the proportionate participation rights of each security type in the Company's undistributed income. The Company's Series A, B and C common stock and the Series C convertible preferred stock are treated as one class for purposes of applying the two-class method, because they have substantially equal rights and share equally on an as converted basis with respect to income available to Discovery Communications, Inc. The table below sets forth the computation for income available to Discovery Communications, Inc. stockholders (in millions).

Series C convertible preferred stockholders for diluted net income per share was $44 million and $34 million , respectively. For the six months ended June 30, 2016 and 2015 , net income available to Discovery Communications, Inc. Series C convertible preferred stockholders for diluted net income per share was $74 million and $64 million , respectively. The table below sets forth the weighted average number of shares outstanding utilized in determining the denominator for basic and diluted earnings per share (in millions).

Commitments, Contingencies, And Guarantees	COMMITMENTS, CONTINGENCIES, AND GUARANTEES Commitments In the normal course of business, the Company enters into various commitments, which primarily include programming and talent arrangements, operating and capital leases, employment contracts, arrangements to purchase various goods and services, future funding commitments to equity method investees, and the conditional obligation to issue or acquire additional shares of preferred stock. (See Note 9.) Contingencies Put Rights The Company has granted put rights related to an equity method investment and certain consolidated subsidiaries. Harpo has the right to require the Company to purchase all or part of its interest in OWN for fair value at various dates. No amounts have been recorded by the Company for the Harpo put right. (See Note 3.) Hasbro and J:COM have the right to require the Company to purchase their remaining noncontrolling interests in Discovery Family and Discovery Japan, respectively. The Company recorded the value of the put rights for Discovery Family and Discovery Japan as a component of redeemable equity in the amounts of $211 million and $30 million , respectively. (See Note 8.) Legal Matters The Company is party to various lawsuits and claims in the ordinary course of business, including claims related to employees, vendors, other business partners or patent issues. However, a determination as to the amount of the accrual required for such contingencies is highly subjective and requires judgment about future events. Although the outcome of these matters cannot be predicted with certainty and the impact of the final resolution of these matters on the Company's results of operations in a particular subsequent reporting period is not known, management does not believe that the resolution of these matters will have a material adverse effect on the Company's consolidated financial position, future results of operations or cash flows. Guarantees There were no guarantees recorded as of June 30, 2016 and December 31, 2015 . The Company may provide or receive indemnities intended to allocate business transaction risks. Similarly, the Company may remain contingently liable for certain obligations of a divested business in the event that a third party does not fulfill its obligations under an indemnification obligation. The Company records a liability for its indemnification obligations and other contingent liabilities when probable and estimable. There were no material amounts for indemnifications or other contingencies recorded as of June 30, 2016 and December 31, 2015 .

The Company evaluates the operating performance of its segments based on financial measures such as revenues and adjusted operating income before depreciation and amortization (“Adjusted OIBDA”). Adjusted OIBDA is defined as operating income excluding: (i) mark-to-market equity-based compensation, (ii) depreciation and amortization, (iii) amortization of deferred launch incentives, (iv) restructuring and other charges, (v) certain impairment charges, (vi) gains and losses on business and asset dispositions, and (vii) certain inter-segment eliminations related to production studios. The Company uses this measure to assess the operating results and performance of its segments, perform analytical comparisons, identify strategies to improve performance and allocate resources to each segment. The Company believes Adjusted OIBDA is relevant to investors because it allows them to analyze the operating performance of each segment using the same metric management uses. The Company excludes mark-to-market equity-based compensation, restructuring and other charges, certain impairment charges, and gains and losses on business and asset dispositions from the calculation of Adjusted OIBDA due to their volatility. The Company also excludes depreciation of fixed assets, amortization of intangible assets and deferred launch incentives, as these amounts do not represent cash payments in the current reporting period. Certain corporate expenses are excluded from segment results to enable executive management to evaluate segment performance based upon the decisions of segment executives. Adjusted OIBDA should be considered in addition to, but not a substitute for, operating income, net income and other measures of financial performance reported in accordance with GAAP. The tables below present summarized financial information for each of the Company’s reportable segments, other operating segments and corporate and inter-segment eliminations (in millions).

On April 28, 2016 , the Company committed to a cost-savings plan that encompasses a series of actions intended to enable the Company to more efficiently operate in a leaner and more directed cost structure and invest in growth initiatives, including digital services and content creation. The cost-savings plan includes significant employee terminations. Other charges during 2015 result from content impairments primarily at the Company's U.S. Networks segment due to the cancellation of certain high profile series as a result of legal circumstances pertaining to the associated talent. Restructuring and other charges are recorded in accrued liabilities on the consolidated balance sheet. Changes in restructuring and other liabilities by major category were as follows (in millions).

Condensed Financial Information of Parent Company Only Disclosure [Abstract]
Condensed Consolidating Financial Statements	CONDENSED CONSOLIDATING FINANCIAL STATEMENTS Overview As of June 30, 2016 and December 31, 2015 , all of the outstanding senior notes have been issued by DCL, a wholly owned subsidiary of the Company, pursuant to one or more Registration Statements on Form S-3 filed with the U.S. Securities and Exchange Commission ("SEC"). (See Note 6.) The Company fully and unconditionally guarantees the senior notes on an unsecured basis. Each of the Company, DCL, and/or Discovery Communications Holding LLC (“DCH”) (collectively the “Issuers”) may issue additional debt securities under the Company's current Registration Statement on Form S-3 that are fully and unconditionally guaranteed by the other Issuers. Set forth below are condensed consolidating financial statements presenting the financial position, results of operations and comprehensive income and cash flows of (i) the Company, (ii) DCH, (iii) DCL, (iv) the non-guarantor subsidiaries of DCL on a combined basis, (v) the other non-guarantor subsidiaries of the Company on a combined basis, and (vi) reclassifications and eliminations necessary to arrive at the consolidated financial statement balances for the Company. DCL and the non-guarantor subsidiaries of DCL are the primary operating subsidiaries of the Company. DCL primarily includes the Discovery Channel and TLC networks in the U.S. The non-guarantor subsidiaries of DCL include substantially all of the Company’s other U.S. and international networks, education businesses, production companies, and most of the Company’s websites and digital distribution arrangements. The non-guarantor subsidiaries of DCL are wholly owned subsidiaries of DCL with the exception of certain equity method investments. DCL is a wholly owned subsidiary of DCH. The Company wholly owns DCH through a 33 1/3% direct ownership interest and a 66 2/3% indirect ownership interest through Discovery Holding Company (“DHC”), a wholly owned subsidiary of the Company. DHC is included in the other non-guarantor subsidiaries of the Company. Basis of Presentation Solely for purposes of presenting the condensed consolidating financial statements, investments in the Company’s subsidiaries have been accounted for by their respective parent company using the equity method. Accordingly, in the following condensed consolidating financial statements the equity method has been applied to (i) the Company’s interests in DCH and the other non-guarantor subsidiaries of the Company, (ii) DCH’s interest in DCL, and (iii) DCL’s interests in the non-guarantor subsidiaries of DCL. Inter-company accounts and transactions have been eliminated to arrive at the consolidated financial statement amounts for the Company. The Company’s accounting bases in all subsidiaries, including goodwill and recognized intangible assets, have been “pushed down” to the applicable subsidiaries. The operations of certain of the Company’s international subsidiaries are excluded from the Company’s consolidated U.S. income tax return. Tax expense related to permanent differences has been allocated to the entity that created the difference. Tax expense related to temporary differences has been allocated to the entity that created the difference, where identifiable. The remaining temporary differences are allocated to each entity included in the Company’s consolidated U.S. income tax return based on each entity’s relative pretax income. Deferred taxes have been allocated based upon the temporary differences between the carrying amounts of the respective assets and liabilities of the applicable entities. The condensed consolidating financial statements should be read in conjunction with the consolidated financial statements of the Company.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use Of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates, judgments and assumptions that affect the amounts and disclosures reported in the consolidated financial statements and accompanying notes. Management continually re-evaluates its estimates, judgments and assumptions, and management’s evaluation could change. These estimates are sometimes complex, sensitive to changes in assumptions and require fair value determinations using Level 3 fair value measurements. Actual results may differ materially from those estimates. Estimates inherent in the preparation of the consolidated financial statements include accounting for asset impairments, revenue recognition, allowances for doubtful accounts, content rights, depreciation and amortization, business combinations, equity-based compensation, income taxes, other financial instruments, contingencies and the determination of whether the Company is the primary beneficiary of entities in which it holds variable interests.
Description of New Accounting Pronouncements Adopted	Accounting and Reporting Pronouncements Adopted Business Consolidation In February 2015, the Financial Accounting Standards Board ("FASB") issued guidance that amends the analysis that a reporting entity performs to determine whether it should consolidate certain legal entities. The changes in this guidance include how related parties and de facto agents are considered in the primary beneficiary determination and the analysis for determining whether a fee paid to a decision maker or service provider is a variable interest. The new standard is effective for reporting periods beginning after December 15, 2015 and can be adopted either retrospectively or using a modified retrospective approach by recording a cumulative-effect adjustment to stockholders' equity as of the beginning of the fiscal year of adoption. The Company adopted this guidance effective January 1, 2016, and there was no effect on the consolidated financial statements. Business Combinations In September 2015, the FASB issued new guidance on adjustments to provisional amounts recognized in a business combination, which are currently recognized on a retrospective basis. Under the new requirements, adjustments will be recognized in the reporting period in which the adjustments are determined. The effects of changes in depreciation, amortization, or other income arising from changes to the provisional amounts, if any, are included in earnings of the reporting period in which the adjustments to the provisional amounts are determined. An entity is also required to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The Company adopted this guidance effective January 1, 2016, and there was no effect on the consolidated financial statements. Accounting for Fees Paid in a Cloud Computing Arrangement In April 2015, the FASB issued explicit guidance on the recognition of fees paid by a customer for cloud computing arrangements as either the acquisition of a software license or a service contract. The Company adopted this guidance effective October 1, 2015, and there was no material effect on the consolidated financial statements. Presentation of Debt Issuance Costs In April 2015, the FASB issued guidance requiring all debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the debt instead of being presented as an asset on the balance sheet. The Company retrospectively adopted the new guidance effective April 1, 2015 and reclassified its unamortized debt issuance costs related to the Company's debt from other noncurrent assets to noncurrent portion of debt on the consolidated balance sheet as of December 31, 2014.
Accounting and Reporting Pronouncements Not Yet Adopted	Accounting and Reporting Pronouncements Not Yet Adopted Share-Based Payment In March 2016, the FASB issued guidance that simplifies how share-based payments are accounted for and presented in the financial statements. The new guidance includes requirements to record all of the tax effects related to share-based payments at settlement through the income statement, allows for tax withholdings up to maximum statutory rates before precluding equity accounting, and allows the Company to make an accounting policy election for the impact of forfeitures on the recognition of expense. The new standard is effective for reporting periods beginning after December 15, 2016 and can be adopted early in any interim period, with any adjustments reflected as of the beginning of the fiscal year of adoption in retained earnings. The Company is currently evaluating the impact that the pronouncement will have on the consolidated financial statements. Leases In February 2016, the FASB issued guidance on leases that will require lessees to recognize almost all of their leases on the balance sheet by recording a right-of-use asset and liability. The new standard will be effective for reporting periods beginning after December 15, 2018, and requires application of the new accounting guidance at the beginning of the earliest comparative period presented in the year of adoption. The Company is currently evaluating the impact that the pronouncement will have on the consolidated financial statements. Recognition and Measurement of Financial Instruments In January 2016, the FASB issued guidance regarding the classification and measurement of financial instruments, which significantly revises the classification and measurement of investments in equity securities. This standard requires equity securities to be measured at fair value with changes in the fair value recognized through net income, and supersedes the guidance permitting entities to record gains and losses on equity securities with readily determinable fair values in accumulated other comprehensive income. Investments accounted for under the equity method of accounting or that result in consolidation are not included within the scope of this update. The new standard will be effective for reporting periods beginning after December 15, 2017. This pronouncement is expected to impact the Company's accounting for changes in the fair value of available-for-sale ("AFS") securities. Balance Sheet Classification of Deferred Taxes In November 2015, the FASB issued guidance to simplify the presentation of deferred income taxes, which removes the requirement to separate deferred tax liabilities and assets into current and noncurrent amounts and instead requires all such amounts be classified as noncurrent on the Company's consolidated balance sheets. The new requirement will be effective for financial statements issued for annual periods beginning after December 15, 2016, and can be adopted on either a retrospective or prospective basis. The Company is currently evaluating the impact that the pronouncement will have on the consolidated financial statements. Presentation of Financial Statements - Going Concern In August 2014, the FASB issued guidance requiring the Company to perform interim and annual assessments regarding conditions or events that raise substantial doubt about the Company's ability to continue as a going concern and to provide related disclosures, if applicable. The new standard is effective for reporting periods ending after December 15, 2016, with early adoption permitted. The adoption of this standard is not expected to have a material effect on the consolidated financial statements. Revenue from Contracts with Customers In May 2014, the FASB issued an accounting pronouncement related to revenue recognition, which applies a single, comprehensive revenue recognition model for all contracts with customers. This standard, as amended, contains principles with respect to the measurement and timing of recognition of revenue. The Company will recognize revenue to reflect the transfer of goods or services to customers at an amount that it expects to be entitled to receive in exchange for those goods or services. The new standard is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. The Company is required to apply the new revenue standard beginning in the first interim period within the year of adoption. The Company is currently evaluating the impact that the pronouncement will have on the consolidated financial statements.
Concentrations Risk	Concentrations Risk Customers The Company has long-term contracts with distributors around the world. For the U.S. Networks segment, more than 90% of distribution revenue comes from the Company's top 10 distributors in the U.S. For the International Networks segment, approximately 45% of distribution revenue comes from the Company's top 10 distributors outside of the U.S. Agreements in place with the major cable and satellite operators in the U.S. expire at various times in 2016 through 2021 . One of the Company's top 10 U.S. distribution agreements has been extended under a short-term agreement. Although the Company seeks to renew its agreements with its distributors prior to expiration of a contract, a delay in securing a renewal that results in a service disruption, a failure to secure a renewal or a renewal on less favorable terms may have a material adverse effect on the Company’s financial condition and results of operations. Not only could the Company experience a reduction in distribution revenue, but it could also experience a reduction in advertising revenue, as viewership is impacted by affiliate subscriber levels. No individual customer accounted for more than 10% of total consolidated revenues for the three and six months ended June 30, 2016 or 2015 . As of June 30, 2016 and December 31, 2015 , the Company’s trade receivables did not represent a significant concentration of credit risk as the customers and markets in which the Company operates are varied and dispersed across many geographic areas. Financial Institutions Cash and cash equivalents are maintained with several financial institutions. The Company has deposits held with banks that exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputable credit and, therefore, bear minimal credit risk. Additionally, the Company has cash and cash equivalents held by its foreign subsidiaries that would result in U.S. tax consequences should the Company decide it needs to repatriate these funds to the U.S. Lender Counterparties There is a risk that the counterparties associated with the Company’s revolving credit facility will not be available to fund as obligated under the terms of the facility and that the Company may, at the time of such unavailability to fund, have limited or no access to the commercial paper market. If funding under the revolving credit facility is unavailable, the Company may have to acquire a replacement credit facility from different counterparties at a higher cost or may be unable to find a suitable replacement. Typically, the Company seeks to manage such risks from its revolving credit facility by contracting with experienced large financial institutions and monitoring the credit quality of its lenders. As of June 30, 2016 , the Company did not anticipate nonperformance by any of its counterparties.

Derivative Financial Instrume27

Derivative Financial Instruments (Policies)	6 Months Ended
	Jun. 30, 2016
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives, Policy [Policy Text Block]	The cash flows from the effective portion of derivative instruments used as hedges are classified in the consolidated statements of cash flows in the same section as the cash flows from the hedged item. For example, the cash paid or received to settle the effective portion of foreign exchange derivatives intended to hedge distribution revenue earned during the six months ended June 30, 2016 is reported as an operating activity in the consolidated statements of cash flows consistent with the classification of cash received from customers. The cash flows from the ineffective portion of derivative instruments used as hedges and derivative contracts not designated as hedges are reported as investing activities in the consolidated statements of cash flows. Gains and losses on the effective portion of designated cash flow hedges are initially recorded in accumulated other comprehensive loss on the consolidated balance sheets and reclassified into the statements of operations in the same line item in which the hedged item is recorded and in the same period as the hedged item affects earnings. If it becomes probable that a forecasted transaction will not occur, any related gains and losses recorded in accumulated other comprehensive loss on the consolidated balance sheets are reclassified to other income (expense), net on the consolidated statements of operations in that period. Changes in the fair value of these cross-currency swaps, designated as hedges of net investments in foreign operations, are reported in the same manner as translation adjustments to the extent that they are effective. Changes in the value of the investment due to changes in spot rates are offset by fair value changes in the effective portion of the derivative instrument. Both changes are recorded as cumulative translation adjustments, a component of accumulated other comprehensive loss , and are only recognized in earnings upon the liquidation or sale of the hedged investment. If the notional amount of the instrument designated as the hedge of a net investment is greater than the portion of the net investment being hedged, hedge ineffectiveness, which is the gain or loss of the portion over hedged, is reclassified to other income (expense), net on the consolidated statements of operations in that period. The Company records gains and losses from the Lionsgate Collar as a component of other income (expense), net on the consolidated statement of operations. The Company uses derivative financial instruments to modify its exposure to market risks from changes in foreign currency exchange rates, interest rates and the fair value of investments classified as AFS securities. Derivative financial instruments that qualify for hedge accounting have been designated as cash flow hedges, net investment hedges and fair value hedges as applicable. The Company does not enter into or hold derivative financial instruments for speculative trading purposes.
Derivatives, Offsetting Fair Value Amounts, Policy [Policy Text Block]	The Company records all unsettled derivative contracts at their gross fair values on the consolidated balance sheets. (See Note 4.)

Redeemable Noncontrolling Int28

Redeemable Noncontrolling Interests (Policies)	6 Months Ended
	Jun. 30, 2016
Noncontrolling Interest [Abstract]
Redeemable noncontrolling interests [Policy Text Block]	Redeemable noncontrolling interests reflected as of the balance sheet date are the greater of the noncontrolling interest balances adjusted for comprehensive income items and distributions or the redemption values remeasured at the period end foreign exchange rates (i.e., the "floor"). Adjustments to the carrying amount of redeemable noncontrolling interests to redemption value as a result of changes in exchange rates are reflected in currency translation adjustments, a component of other comprehensive (loss) income ; however, such currency translation adjustments to redemption value are allocated to Discovery stockholders only. Redeemable noncontrolling interest adjustments of redemption value to the floor are reflected in retained earnings. Any adjustment of redemption value to the floor that reflects a redemption in excess of fair value is included as an adjustment to net income available to Discovery stockholders in the calculation of earnings per share. There were no current period adjustments to reflect a redemption in excess of fair value. (See Note 12.)

Earnings Per Share (Policies)

Earnings Per Share (Policies)	6 Months Ended
	Jun. 30, 2016
Earnings Per Share [Abstract]
Earnings Per Share, Policy [Policy Text Block]	The computation of the diluted earnings per share of Series A, B and C common stockholders assumes the conversion of Series A and C convertible preferred stock, while the diluted earnings per share amounts of Series C convertible preferred stock does not assume conversion of those shares. In calculating earnings per share, the Company follows the two-class method, which distinguishes between the classes of securities based on the proportionate participation rights of each security type in the Company's undistributed income. The Company's Series A, B and C common stock and the Series C convertible preferred stock are treated as one class for purposes of applying the two-class method, because they have substantially equal rights and share equally on an as converted basis with respect to income available to Discovery Communications, Inc. The weighted average number of diluted shares outstanding adjusts the weighted average number of shares of Series A, B and C common stock outstanding for the potential dilution that would occur if common stock equivalents, including convertible preferred stock and equity-based awards, were converted into common stock or exercised, calculated using the treasury stock method. Series A, B and C diluted common stock includes the impact of the conversion of Series A preferred stock, the impact of the conversion of Series C preferred stock, and the impact of equity-based compensation.

Segment Reporting [Abstract]
Segment Reporting, Policy [Policy Text Block]	The accounting policies of the reportable segments are the same as the Company’s, except that certain inter-segment transactions that are eliminated for consolidation are not eliminated at the segment level. Inter-segment transactions primarily include advertising and content purchases.
Adjusted OIBDA, Policy [Policy Text Block]	The Company believes Adjusted OIBDA is relevant to investors because it allows them to analyze the operating performance of each segment using the same metric management uses. The Company excludes mark-to-market equity-based compensation, restructuring and other charges, certain impairment charges, and gains and losses on business and asset dispositions from the calculation of Adjusted OIBDA due to their volatility. The Company also excludes depreciation of fixed assets, amortization of intangible assets and deferred launch incentives, as these amounts do not represent cash payments in the current reporting period.

Condensed Statement of Income Captions [Line Items]
Condensed Consolidating Financial Statements	CONDENSED CONSOLIDATING FINANCIAL STATEMENTS Overview As of June 30, 2016 and December 31, 2015 , all of the outstanding senior notes have been issued by DCL, a wholly owned subsidiary of the Company, pursuant to one or more Registration Statements on Form S-3 filed with the U.S. Securities and Exchange Commission ("SEC"). (See Note 6.) The Company fully and unconditionally guarantees the senior notes on an unsecured basis. Each of the Company, DCL, and/or Discovery Communications Holding LLC (“DCH”) (collectively the “Issuers”) may issue additional debt securities under the Company's current Registration Statement on Form S-3 that are fully and unconditionally guaranteed by the other Issuers. Set forth below are condensed consolidating financial statements presenting the financial position, results of operations and comprehensive income and cash flows of (i) the Company, (ii) DCH, (iii) DCL, (iv) the non-guarantor subsidiaries of DCL on a combined basis, (v) the other non-guarantor subsidiaries of the Company on a combined basis, and (vi) reclassifications and eliminations necessary to arrive at the consolidated financial statement balances for the Company. DCL and the non-guarantor subsidiaries of DCL are the primary operating subsidiaries of the Company. DCL primarily includes the Discovery Channel and TLC networks in the U.S. The non-guarantor subsidiaries of DCL include substantially all of the Company’s other U.S. and international networks, education businesses, production companies, and most of the Company’s websites and digital distribution arrangements. The non-guarantor subsidiaries of DCL are wholly owned subsidiaries of DCL with the exception of certain equity method investments. DCL is a wholly owned subsidiary of DCH. The Company wholly owns DCH through a 33 1/3% direct ownership interest and a 66 2/3% indirect ownership interest through Discovery Holding Company (“DHC”), a wholly owned subsidiary of the Company. DHC is included in the other non-guarantor subsidiaries of the Company. Basis of Presentation Solely for purposes of presenting the condensed consolidating financial statements, investments in the Company’s subsidiaries have been accounted for by their respective parent company using the equity method. Accordingly, in the following condensed consolidating financial statements the equity method has been applied to (i) the Company’s interests in DCH and the other non-guarantor subsidiaries of the Company, (ii) DCH’s interest in DCL, and (iii) DCL’s interests in the non-guarantor subsidiaries of DCL. Inter-company accounts and transactions have been eliminated to arrive at the consolidated financial statement amounts for the Company. The Company’s accounting bases in all subsidiaries, including goodwill and recognized intangible assets, have been “pushed down” to the applicable subsidiaries. The operations of certain of the Company’s international subsidiaries are excluded from the Company’s consolidated U.S. income tax return. Tax expense related to permanent differences has been allocated to the entity that created the difference. Tax expense related to temporary differences has been allocated to the entity that created the difference, where identifiable. The remaining temporary differences are allocated to each entity included in the Company’s consolidated U.S. income tax return based on each entity’s relative pretax income. Deferred taxes have been allocated based upon the temporary differences between the carrying amounts of the respective assets and liabilities of the applicable entities. The condensed consolidating financial statements should be read in conjunction with the consolidated financial statements of the Company.
