Accounting Policies [Abstract]
Description of Business and Basis of Presentation	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Description of Business Discovery, Inc. (“Discovery”, the “Company”, "we", "us" or "our") is a global media company that provides content across multiple distribution platforms, including linear platforms such as pay-television ("pay-TV"), free-to-air ("FTA") and broadcast television, authenticated TV Everywhere ("TVE") applications, digital distribution arrangements, content licensing arrangements and direct-to-consumer ("DTC") subscription products. The Company also operates a production studio. The Company has organized its operations into two reportable segments: U.S. Networks, consisting principally of domestic television networks and digital content services, and International Networks, consisting primarily of international television networks and digital content services. Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Discovery and its majority-owned subsidiaries in which a controlling interest is maintained, including variable interest entities ("VIE") for which the Company is the primary beneficiary. Inter-company accounts and transactions between consolidated entities have been eliminated. 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, 2019 (the “2019 Form 10-K”). Use of Estimates The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from these estimates. Significant estimates and judgments inherent in the preparation of the consolidated financial statements include accounting for asset impairments, revenue recognition, estimated credit losses, content rights, leases, depreciation and amortization, business combinations, share-based compensation, defined benefit plans, income taxes, other financial instruments, contingencies, and the determination of whether the Company should consolidate certain entities. Impact of COVID-19 On March 11, 2020, the World Health Organization declared the current novel coronavirus (“COVID-19”) outbreak to be a global pandemic. COVID-19 continues to spread throughout the world, and the duration and severity of its effects and economic disruption are currently unknown. In response to this declaration and the rapid spread of COVID-19, the United States and other countries throughout the world have imposed varying degrees of restrictions on social and commercial activity in an effort to slow the spread of the illness. These measures have begun to have a significant adverse impact upon many sectors of the economy, including the media industry. The Company is closely monitoring the impact of COVID-19 on all aspects of its business and geographies, including how it will impact its customers, employees, suppliers, vendors, distribution and advertising partners, production facilities, and various third parties. While the Company did not incur significant disruptions during the three months ended March 31, 2020, the Company has taken certain steps to mitigate the adverse impacts on and risks to the Company's business in light of the pandemic. The Company is unable to predict the full impact that COVID-19 will have on its financial position, operating results, and cash flows due to numerous uncertainties and the speed with which the COVID-19 situation is developing. The extent to which COVID-19 impacts the Company’s results will depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of COVID-19 and the actions to contain the virus or treat its impact, among others. The Company’s consolidated financial statements presented herein reflect the latest estimates and assumptions made by management that affect the reported amounts of assets and liabilities and related disclosures as of the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. Actual results may differ significantly from these estimates and assumptions. The Company assessed goodwill, other intangibles, deferred tax assets, programming assets, and accounts receivable for recoverability based upon latest estimates and judgments with respect to expected future operating results, ultimate usage of content and latest expectations with respect to collectability. No asset impairments were recorded as of March 31, 2020, as the fair value of such assets exceeded their carrying value. However, due to significant uncertainty surrounding the situation, management’s judgment regarding this could change in the future. Finally, the effects of the pandemic may negatively impact the Company’s financial position, results of operations, and cash flows. However, the current level of uncertainty over the economic and operational impacts of COVID-19 means the related financial impact cannot be reasonably and fully estimated at this time. In response to the COVID-19 pandemic, during the first quarter of 2020, the Company pursued a number of cost savings initiatives that it believes will offset a portion of potential revenue losses and deferrals due to the impact of COVID-19, through the implementation of travel, marketing, production and other operating cost reductions. The Company also implemented remote work arrangements effective mid-March 2020 and to date, these arrangements have not materially affected our ability to maintain our business operations. Additionally, certain sporting events that the Company has rights to have been cancelled or postponed, thereby eliminating or deferring the related revenues and expenses. For example, on March 24, 2020, the International Olympic Committee and the Tokyo 2020 Organizing Committee agreed to postpone the Olympic Games to 2021. The Company expects that the postponement of the Olympic Games will shift Olympic-related revenues and defer significant expenses from fiscal year 2020 to fiscal year 2021. The Company generally relies on third-party production partners to produce its content, and these third-party production partners were forced to shut down during the first quarter of 2020 due to COVID-19. The Company continues to monitor customer and consumer demands by employing innovative production and programming strategies, including content filmed by our on-air talent and seeking viewer feedback on which content to air. We intend to continue to adapt our plans as needed to drive our business and meet our obligations during the COVID-19 situation. In addition, the Company has implemented several measures that the Company believes will preserve sufficient liquidity in the near term. As described further in Note 7, during March 2020, the Company drew down $500 million under its $2.5 billion revolving credit facility to increase its cash position and maximize flexibility in light of the current uncertainty surrounding the impact of COVID-19. The Company has upcoming corporate debt maturities in June 2020 of $600 million and in June 2021 of $640 million. Subsequent to the three months ended March 31, 2020, the Company entered into an amendment to its revolving credit facility (See Note 19.) Finally, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020 in the United States. The CARES Act provides numerous tax provisions and other stimulus measures, including temporary changes regarding the prior and future utilization of net operating losses, temporary changes to the prior and future limitations on interest deductions, temporary suspension of certain payment requirements for the employer portion of Social Security taxes, technical corrections from prior tax legislation for tax depreciation of certain qualified improvement property, and the creation of certain refundable employee retention credits. As of March 31, 2020, the Company does not expect the CARES Act to have a material effect on its financial position and results of operations. The Company continues to monitor other relief measures taken by the U.S. and other governments around the world. Accounting and Reporting Pronouncements Adopted Content In March 2019, the Financial Standards Accounting Board ("FASB") issued Accounting Standards Update ("ASU") 2019-02, which generally aligns the accounting for production costs of episodic television series with the accounting for production costs of films. In addition, ASU 2019-02 modifies certain aspects of the capitalization, impairment, presentation and disclosure requirements in Accounting Standards Codification (“ASC”) 926-20 and the impairment, presentation and disclosure requirements in ASC 920-350. The Company adopted this ASU on January 1, 2020 and will apply the provisions prospectively. In connection with this adoption, the Company elected to treat all content rights and prepaid license fees as a noncurrent asset, with the exception of content acquired with an initial license period of 12 months or less and prepaid sports rights expected to air within 12 months. As of March 31, 2020 and December 31, 2019, $89 million and $579 million, respectively, of content rights and prepaid license fees were reflected as a current asset. The Company determined that most of its content is exploited as part of film groups. For such content assets, the unit of account for the impairment assessment is the respective film group. There was no material impact to the Consolidated Statements of Operations or the Consolidated Statements of Cash Flows. (See Note 5.) Goodwill In January 2017, the FASB issued ASU 2017-04, which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the former two-step goodwill impairment test and eliminating the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. Therefore, an entity will recognize impairment charges for the amount by which the carrying amount exceeds the reporting unit's fair value not to exceed the amount of goodwill recorded for that reporting unit. Goodwill impairment will no longer be measured as the excess of the carrying amount of goodwill over its implied fair value determined by assigning the fair value of a reporting unit to all of its assets and liabilities as if it had been acquired in a business combination. The Company adopted this ASU on January 1, 2020 and will apply the provisions prospectively to future goodwill impairment tests. Financial Instruments - Credit Losses In June 2016, the FASB issued ASU 2016-13, which changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans and replaces the incurred loss methodology with a new, forward-looking “expected loss” model that considers the risk of loss over the asset’s contractual life, even if remote, historical experience, current conditions, and reasonable and supportable forecasts of future relevant events. The Company adopted this ASU on January 1, 2020 using a modified retrospective approach and recorded a noncash cumulative effect of adoption as an increase to retained earnings of $2 million to align our credit loss methodology with the new standard. (See Note 10.) Accounting and Reporting Pronouncements Not Yet Adopted LIBOR In March 2020, the FASB issued ASU 2020-04, which provides temporary optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships, and other transactions if certain criteria are met in order to ease the potential accounting and financial reporting burden associated with the expected market transition away from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The ASU is effective as of March 12, 2020 through December 31, 2022. The Company is currently assessing the impact ASU 2020-04 will have on its consolidated financial statements and related disclosures, if elected.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS Acquisitions UKTV - Lifestyle Business On June 11, 2019, the Company and BBC Studios (“BBC”) dissolved their 50/50 joint venture, UKTV, a British multi-channel broadcaster, with the Company taking full control of UKTV’s three lifestyle channels (the “Lifestyle Business”) and BBC taking full control of UKTV’s seven entertainment channels (the "Entertainment Business"). Prior to the transaction, the Company held a note receivable from UKTV of $118 million, which was included in equity method investments in the Company’s consolidated balance sheets. Concurrent with the transaction, the note was settled. To compensate Discovery for the note receivable and for the difference in fair value between the Lifestyle Business and the Entertainment Business retained by BBC, Discovery received cash of $88 million at closing and a note receivable from BBC of $130 million, payable in two equal installments in June 2020 and 2021. The Company used a market-based valuation model to determine the fair value of the previously held 50% equity method investment in the Lifestyle Business and recognized a gain of $5 million during the three months ended June 30, 2019 for the difference between the carrying value and the fair value of the of the previously held equity interest. The Company applied the acquisition method of accounting to the Lifestyle Business, whereby the excess of the fair value of the business over the fair value of identifiable net assets was allocated to goodwill. The goodwill reflects the workforce and synergies expected from broader exposure to the lifestyle entertainment sector in the U.K. 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 consist of electronic program guide slots and trademarks and have a weighted average useful life of 6 years. The preliminary opening balance sheet is subject to adjustment based on final assessment of the fair values of certain acquired assets, principally intangibles, and certain liabilities assumed. The Company used discounted cash flow ("DCF") analyses, which represent Level 3 fair value measurements, to assess certain components of its purchase price allocation. As the Company finalizes the fair value of assets acquired and liabilities assumed, additional purchase price adjustments may be recorded during the measurement period. The Company will reflect measurement period adjustments, if any, in the period in which the adjustments occur. The preliminary fair value of Lifestyle Business assets acquired and liabilities assumed, as well as a reconciliation to total assets received in dissolution of the UKTV joint venture, is presented in the table below (in millions). Cash $ 17 Content rights 18 Intangible assets 34 Goodwill 121 Accrued liabilities (12) Total assets acquired and liabilities assumed in Lifestyle Business 178 Note receivable from BBC 130 Cash received 88 Net assets received in dissolution of UKTV joint venture $ 396 A summary of total assets derecognized in connection with the dissolution of the UKTV joint venture is presented in the table below (in millions). Carrying value of UKTV equity method investment $ 278 Settlement of note receivable 118 Total assets derecognized in dissolution of UKTV joint venture $ 396 In connection with the above transaction, the Company contemporaneously entered into a ten-year content licensing arrangement with BBC in exchange for license fees over the term. Other Magnolia Discovery Ventures On July 19, 2019, the Company contributed its linear cable network focused on home improvement, DIY Network, to a new joint venture, Magnolia Discovery Ventures, LLC ("Magnolia"), with Chip and Joanna Gaines acting as Chief Creative Officers to the joint venture. The joint venture will replace and rebrand the DIY Network, include a TV Everywhere app and a subscription streaming service planned for a future date. Upon formation of Magnolia, Discovery received a 75% ownership interest in the joint venture. In exchange for providing services and exclusivity to the joint venture, the Gaines received a 25% ownership interest in the joint venture, a put right after 6.5 years at fair value, potential for an additional 5% incentive equity, and certain guaranteed payments. Discovery consolidated the joint venture under the voting interest consolidation model. Payments to the Gaines for rendering services in their capacity as the Chief Creative Officers of the joint venture will be accounted for as liability-classified share-based awards to non-employees as services are rendered. Golf Digest On May 13, 2019, the Company paid $36 million in cash to acquire Golf Digest, a leading golf brand whose content is available across multiple platforms, including print and social media. The Company applied the acquisition method of accounting to Golf Digest, whereby the excess of the fair value of the business over the fair value of identifiable net assets was allocated to goodwill. The Company recorded preliminary net assets of $36 million, subject to adjustment based on the final assessment of the fair values of the assets acquired and liabilities assumed, including net working capital liabilities of $12 million, intangible assets of $25 million and goodwill of $23 million. Intangible assets consist of trademarks and trade names and licensing agreements and have a weighted average useful life of 9 years. The goodwill reflects the workforce and synergies expected from broader exposure to the golf entertainment sector. The goodwill recorded as part of this acquisition is included in the International Networks reportable segment and is not amortizable for tax purposes. Play Sports Group Limited On January 8, 2019, the Company acquired a controlling interest in Play Sports Group Limited, increasing Discovery's ownership stake from 20.1% to 70.7%. The Company recognized a gain of $8 million during the three months ended March 31, 2019, which represents the difference between the carrying value and the fair value of the previously held 20.1% equity method investment. The gain is included in other expense, net in the Company's consolidated statement of operations. The measurement period closed in January 2020, with no material adjustments recorded.

These investments are considered variable interest entities ("VIEs") of the Company and are accounted for under the equity method of accounting using the Hypothetical Liquidation at Book Value ("HLBV") methodology for allocating earnings. (b) Overall ownership percentage for Group Nine Media is calculated on an outstanding shares basis. (c) Ownership percentage for Formula E includes holdings accounted for as an equity method investment and holdings accounted for as an equity investment without a readily determinable fair value. Equity Method Investments Investments in equity method investees are those for which the Company has the ability to exercise significant influence but does not control and is not the primary beneficiary. There were no impairment losses recorded during the three months ended March 31, 2020 and 2019. With the exception of nC+, the carrying values of the Company’s equity method investments are consistent with its ownership in the underlying net assets of the investees. A portion of the purchase price associated with the investment nC+ was attributed to amortizable intangible assets, which is included in its carrying values. Earnings from nC+ were reduced by the amortization of these intangibles of $3 million and $2 million during the three months ended March 31, 2020 and 2019, respectively. Amortization that reduces the Company's equity in earnings of nC+ for future periods is expected to be $54 million. Certain of the Company's other equity method investments are VIEs, for which the Company is not the primary beneficiary. As of March 31, 2020, the Company’s maximum exposure for all its unconsolidated VIEs, including the investment carrying values and unfunded contractual commitments made on behalf of VIEs, was approximately $303 million. The Company's maximum estimated exposure excludes the non-contractual future funding of VIEs. The aggregate carrying values of these VIE investments were $160 million as of March 31, 2020 and December 31, 2019. The Company recognized its portion of VIE operating results with net losses of $9 million and net earnings $3 million for the three months ended March 31, 2020 and 2019, respectively, in (loss) income from equity investees, net on the consolidated statements of operations. Common Stock Investments with Readily Determinable Fair Value Investments in entities or other securities in which the Company has no control or significant influence, is not the primary beneficiary, and have a readily determinable fair value are classified as equity investments with readily determinable fair value. Gains and losses are recorded in other expense, net on the consolidated statements of operations. The Company owns shares of common stock of Lions Gate Entertainment Corp. ("Lionsgate"), an entertainment company. The gains and losses related to the Company's common stock investments with readily determinable fair values for the three months ended March 31, 2020 and 2019 are summarized in the table below (in millions). Three Months Ended March 31, 2020 2019 Net losses recognized during the period on equity securities $ (22) $ — Less: Net losses recognized on equity securities sold — — Unrealized losses recognized during reporting period on equity securities still held at the reporting date $ (22) $ — Formerly, the Company hedged 50% of the Lionsgate shares with an equity collar (the "Lionsgate Collar") and pledged those shares as collateral to the derivative counterparty with changes in fair value reflected as a component of other expense, net on the consolidated statements of operations. (See Note 8.) During the three months ended March 31, 2020, tranches 2 and 3 of the Lionsgate Collar, which covered the remaining hedged shares, were terminated. The Company received cash of $44 million and recognized a gain of $7 million, which represents the difference between the carrying value and the fair value of the hedged shares, upon termination. The gain is included in other expense, net on the consolidated statements of operations. Equity investments without readily determinable fair values assessed under the measurement alternative Equity investments without readily determinable fair value include ownership rights that either (i) do not meet the definition of in-substance common stock or (ii) do not provide the Company with control or significant influence and these investments do not have readily determinable fair values. During the three months ended March 31, 2020, the Company invested $6 million in various equity investments without readily determinable fair values and concluded that its other equity investments without readily determinable fair values had no indicators that a change in fair value had taken place as the result of observable price changes in orderly transactions for the identical or a similar investment of the same issuer. As of March 31, 2020, the Company had recorded cumulative upward adjustments of $9 million for its equity investments without readily determinable fair values.

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). March 31, 2020 Category Balance Sheet Location Level 1 Level 2 Level 3 Total Assets Cash equivalents: Time deposits Cash and cash equivalents $ — $ 153 $ — $ 153 Equity securities: Mutual funds Prepaid expenses and other current assets 12 — — 12 Company-owned life insurance contracts Prepaid expenses and other current assets — 3 — 3 Mutual funds Other noncurrent assets 163 — — 163 Company-owned life insurance contracts Other noncurrent assets — 42 — 42 Total $ 175 $ 198 $ — $ 373 Liabilities Deferred compensation plan Accrued liabilities $ 24 $ — $ — $ 24 Deferred compensation plan Other noncurrent liabilities 180 — — 180 Total $ 204 $ — $ — $ 204 December 31, 2019 Category Balance Sheet Location Level 1 Level 2 Level 3 Total Assets Cash equivalents: Time deposits Cash and cash equivalents $ — $ 10 $ — $ 10 Equity securities: Mutual funds Prepaid expenses and other current assets 11 — — 11 Company-owned life insurance contracts Prepaid expenses and other current assets — 4 — 4 Mutual funds Other noncurrent assets 192 — — 192 Company-owned life insurance contracts Other noncurrent assets — 45 — 45 Total $ 203 $ 59 $ — $ 262 Liabilities Deferred compensation plan Accrued liabilities $ 24 $ — $ — $ 24 Deferred compensation plan Other noncurrent liabilities 209 — — 209 Total $ 233 $ — $ — $ 233 Equity securities include investments in mutual funds held in separate trusts, which are owned as part of the Company's supplemental retirement plans, and company-owned life insurance contracts. The fair value of Level 1 equity securities was determined by reference to the quoted market price per share in active markets multiplied by the number of shares 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. Changes in the fair value of the investments are offset by changes in the fair value of the deferred compensation obligation. Company-owned life insurance contracts are recorded at their cash surrender value, which approximates fair value (Level 2). In addition to the financial instruments listed in the tables above, the Company has other financial instruments, including cash deposits, accounts receivable, accounts payable, borrowings under the revolving credit facility, finance leases, and senior notes. The carrying values for such financial instruments, other than the senior notes, each approximated their fair values as of March 31, 2020 and December 31, 2019. The estimated fair value of the Company’s outstanding senior notes using quoted prices from over-the-counter markets, considered Level 2 inputs, was $15.7 billion and $17.1 billion as of March 31, 2020 and December 31, 2019, respectively. The Company's derivative financial instruments are discussed in Note 8.

Content Rights

Intangible Assets, Net (Excluding Goodwill) [Abstract]
Content Rights	CONTENT RIGHTS Content rights principally consist of television series, specials, films and sporting events. Content aired on the Company’s television networks and digital content offerings is sourced from a wide range of third-party producers, wholly-owned and equity method investee production studios, and sports associations. Content is classified either as produced, coproduced or licensed. The Company owns most or all of the rights to produced content. The Company collaborates with third parties to finance and develop coproduced content, and it retains significant rights to exploit the programs. Prepaid licensed content includes advance payments for rights to air sporting events that will take place in the future and advance payments for acquired films and television series. Costs of produced and coproduced content consist of development costs, acquired production costs, direct production costs, certain production overhead costs and participation costs. Costs incurred for produced and coproduced content are capitalized if the Company has previously generated revenues from similar content in established markets and offerings and the content will be used, and revenues will be generated for a period of at least one year. The Company’s coproduction arrangements generally provide for the sharing of production costs. The Company records its costs but does not record the costs borne by the other party as the Company does not share any associated economics of exploitation. Licensed content is comprised of films or series that have been previously produced by third parties and the Company retains limited airing rights over a contractual term. Program licenses typically have fixed terms and require payments during the term of the license. The cost of licensed content is capitalized when the cost is known or reasonably determinable, the license period for the programs has commenced, the program materials have been accepted by the Company in accordance with the license agreements, and the programs are available for the first showing. The Company pays in advance of delivery for television series, specials, films and sports rights. Payments made in advance of when the right to air the content is received are recognized as prepaid licensed content. Participation costs are expensed in line with the amortization of production costs. Content distribution, advertising, marketing, general and administrative costs are expensed as incurred. Linear content amortization expense for each period is recognized based on the revenue forecast model, which approximates the proportion that estimated distribution and advertising revenues for the current period represent in relation to the estimated remaining total lifetime revenues. Digital content amortization for each period is recognized based on estimated viewing patterns as there are no direct revenues to associate to the individual content assets and therefore, number of views is most representative of the use of the title. Significant judgement is required to determine the useful lives and amortization patterns of the Company’s content assets. Quarterly, the Company prepares analyses to support its content amortization expense. Critical assumptions used in determining content amortization include: (i) the grouping of content with similar characteristics, (ii) the application of a quantitative revenue forecast model or viewership model based on the adequacy of historical data, (iii) determining the appropriate historical periods to utilize and the relative weighting of those historical periods in the forecast model, (iv) assessing the accuracy of the Company's forecasts and (v) incorporating secondary streams. The Company then considers the appropriate application of the quantitative assessment given forecasted content use, expected content investment and market trends. Content use and future revenues may differ from estimates based on changes in expectations related to market acceptance, network affiliate fee rates, advertising demand, the number of cable and satellite television subscribers receiving the Company’s networks, the number of subscribers to our digital services, and program usage. Accordingly, the Company continually reviews its estimates and planned usage and revises its assumptions if necessary. As part of the Company's assessment of its amortization rates, the Company compares the calculated amortization rates to those that have been utilized during the year. If the calculated rates do not deviate materially from the applied amortization rates, no adjustment is recorded. Any material adjustments from the Company’s review of the amortization rates are applied prospectively in the period of the change for assets in film groups, which represent the largest proportion of the Company's content assets. The result of the content amortization analysis is either an accelerated method or a straight-line amortization method over the estimated useful lives of two to four years. Amortization of capitalized costs for produced and coproduced content begins when a program has been aired. Amortization of capitalized costs for licensed content generally commences when the license period begins and the program is available for use. The Company allocates the cost of multi-year sports programming arrangements over the contract period of each event or season based on the estimated relative value of each event or season. Amortization of sports rights takes place when the content airs. Capitalized content costs are stated at the lower of cost less accumulated amortization or fair value. Content assets (produced, coproduced and licensed) are predominantly monetized as a group on the Company’s linear networks and digital content offerings. For content assets that are predominantly monetized within film groups, the Company evaluates the fair value of content in aggregate at the group level by considering expected future revenue generation typically by using a discounted cash flow analysis when an event or change in circumstances indicates a change in the expected usefulness of the content or that the fair value may be less than unamortized costs. Estimates of future revenues consider historical airing patterns and future plans for airing content, including any changes in strategy. Given the significant estimates and judgments involved, actual demand or market conditions may be less favorable than those projected, requiring a write-down to fair value. Programming and development costs for programs that the Company has determined will not be produced, are fully expensed in the period the determination is made. The Company’s film groups are generally aligned along the Company’s networks and digital content offerings except for certain international territories wherein content assets are shared across the various networks in the territory and therefore, the territory is the film group. The Company’s rights to the Olympics are predominantly monetized on their own as the sublicensing of the rights in certain territories is a significant component of the monetization strategy. Beginning in 2020, all content rights and prepaid license fees are classified as a noncurrent asset, with the exception of content acquired with an initial license period of 12 months or less and prepaid sports rights expected to air within 12 months. (See Note 1.) The table below presents the components of content rights (in millions). March 31, 2020 December 31, 2019 Produced content rights: Completed $ 7,171 $ 6,976 In-production 715 582 Coproduced content rights: Completed 915 882 In-production 50 50 Licensed content rights: Acquired 1,100 1,101 Prepaid 390 249 Content rights, at cost 10,341 9,840 Accumulated amortization (6,496) (6,132) Total content rights, net 3,845 3,708 Current portion (a) (89) (579) Noncurrent portion $ 3,756 $ 3,129 (a) Effective with the adoption of ASU 2019-02 on January 1, 2020, the Company elected to classify all content rights and prepaid license fees as a noncurrent asset, with the exception of content acquired with an initial license period of 12 months or less and prepaid sports rights expected to air within 12 months. Content expense consisted of the following (in millions).

Senior Notes In the second quarter of 2019, Discovery Communications, LLC (“DCL”), a wholly-owned subsidiary of the Company, issued aggregate principal amount of Senior Notes of $750 million due 2029 and $750 million due 2049. The proceeds received by DCL were net of a $6 million issuance discount and $12 million of debt issuance costs. DCL used the proceeds from the offering to redeem and repurchase approximately $1.3 billion aggregate principal amount of DCL's and Scripps Networks' Senior Notes. The redemptions and repurchase resulted in a loss on extinguishment of debt of $23 million for the year ended December 31, 2019. The loss included $20 million of net premiums to par value and $3 million of other non-cash charges. In the first quarter of 2019, the Company redeemed $411 million aggregate principal amount of senior notes due in 2019 and, during 2019, made open market bond repurchases of $55 million, resulting in a loss on extinguishment of debt of $5 million. As of March 31, 2020, all senior notes are fully and unconditionally guaranteed by the Company and Scripps Networks, except for the remaining $135 million of un-exchanged Scripps Networks Senior Notes acquired in conjunction with the acquisition of Scripps Networks. (See Note 20.) Revolving Credit Facility and Commercial Paper Programs DCL and certain designated foreign subsidiaries of DCL have the capacity to borrow up to $2.5 billion under a revolving credit facility (the "Credit Facility"), including a $100 million sublimit for the issuance of standby letters of credit and a $50 million sublimit for Euro-denominated swing line loans. The Credit Facility matures in August 2022 with the option for up to two additional 364-day renewal periods and is subject to a maximum consolidated leverage ratio financial covenant of 4.50 to 1.00. As of March 31, 2020, DCL, was in compliance with all covenants and there were no events of default under the revolving credit facility. Subsequent to the three months ended March 31, 2020, the Company entered into an amendment to the Credit Facility. (See Note 19.) Additionally, the Company's commercial paper program is supported by the Credit Facility. Under the commercial paper program, the Company may issue up to $1.5 billion, including up to $500 million of euro-denominated borrowings. Borrowing capacity under the Credit Facility is reduced by any outstanding borrowings under the commercial paper program. As of March 31, 2020, the Company had $500 million of outstanding borrowings under the Credit Facility at a weighted average interest rate of 2.10% and had no outstanding borrowings under the commercial paper program.

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 and interest rates. The Company does not enter into or hold derivative financial instruments for speculative trading purposes. During the three months ended March 31, 2020, the Company executed forward starting interest rate swap contracts designated as cash flow hedges with a total notional value of $1.6 billion. These contracts will mitigate interest rate risk associated with the forecasted issuance of future fixed-rate public debt. The following table summarizes the impact of derivative financial instruments on the Company's consolidated balance sheets (in millions). There were no amounts eligible to be offset under master netting agreements as of March 31, 2020 and December 31, 2019.

Equity	EQUITY Repurchase Programs In February 2020, the Company's Board of Directors authorized additional stock repurchases of up to $2 billion upon completion of its existing $1 billion repurchase authorization announced in May 2019. Under the stock repurchase authorization, management is authorized to purchase shares from time to time through open market purchases at prevailing prices or privately negotiated purchases subject to market conditions and other factors. During the three months ended March 31, 2020, the Company repurchased 19.4 million shares of its Series C common stock for $523 million at an average price of $26.87 per share. There were no common stock repurchases for the three months ended March 31, 2019. All common stock repurchases, including prepaid common stock repurchase contracts, have been made through open market transactions and have been recorded as treasury stock on the consolidated balance sheet. Over the life of the Company's repurchase programs and as of March 31, 2020, the Company had repurchased 3 million and 206 million shares of Series A and Series C common stock, respectively, for an aggregate purchase price of $171 million and $7.7 billion, respectively.

Revenue from Contract with Customer [Abstract]
Revenues	REVENUES AND ACCOUNTS RECEIVABLE Disaggregated Revenue The following table presents the Company’s revenues disaggregated by revenue source (in millions). Management uses these categories of revenue to evaluate the performance of its businesses and to assess its financial results and forecasts. Three Months Ended March 31, 2020 2019 U.S. Networks International Networks Other Total U.S. Networks International Networks Other Total Revenues: Advertising $ 1,026 $ 376 $ — $ 1,402 $ 1,022 $ 393 $ — $ 1,415 Distribution 708 515 — 1,223 697 527 — 1,224 Other 22 32 4 58 33 32 3 68 Total $ 1,756 $ 923 $ 4 $ 2,683 $ 1,752 $ 952 $ 3 $ 2,707 Accounts Receivable and Credit Losses Receivables include amounts currently due from customers and are presented net of an estimate for lifetime expected credit losses. Allowance for credit losses is measured using historical loss rates for the respective risk categories and incorporating forward-looking estimates. To assess collectability, the Company analyzes market trends, economic conditions, the aging of receivables and customer specific risks, and records a provision for estimated credit losses expected over the lifetime of receivables. The corresponding expense for the expected credit losses is reflected in selling, general and administrative expenses. The Company does not require collateral with respect to trade receivables. The Company’s accounts receivable balances and the related credit losses arise primarily from distribution and advertising revenue. The Company monitors ongoing credit exposure through active review of customers’ financial conditions, aging of receivable balances, historical collection trends, and expectations about relevant future events that may significantly affect collectability. Changes in allowance for credit losses consisted of the following (in millions): December 31, 2019 Impact of adoption of ASU 2016-13 Provisions for credit losses Write-offs March 31, 2020 Distribution customers $ 19 $ 1 $ — $ (2) $ 18 Advertising and other customers 35 (3) 5 (3) 34 Total $ 54 $ (2) $ 5 $ (5) $ 52 Contract Liability A contract liability, such as deferred revenue, is recorded when cash is received in advance of the Company's performance. Total deferred revenues, including both current and noncurrent, were $581 million and $597 million at March 31, 2020 and December 31, 2019, respectively. The change in deferred revenue for the three months ended March 31, 2020 primarily reflects $102 million of revenues recognized that were included in deferred revenues at December 31, 2019, partially offset by cash payments received during the period for which the performance obligation was not satisfied prior to the end of the period. Revenue recognized for the three months ended March 31, 2019 related to the deferred revenue balance at December 31, 2018 was $99 million. Long term deferred revenues is a component of other noncurrent liabilities on the consolidated balance sheets. Transaction Price Allocated to Remaining Performance Obligations Most of the Company's distribution contracts are licenses of functional intellectual property where revenue is derived from royalty-based arrangements, for which the guidance allows the application of a practical expedient to record revenues as a function of royalties earned to date instead of estimating incremental royalty contract revenue. Accordingly, in these instances revenue is recognized based upon the royalties earned to date. However, there are certain other distribution arrangements that are fixed price or contain minimum guarantees that extend beyond one year. The Company recognizes revenue for fixed fee distribution contracts on a monthly basis based on minimum monthly fees or by calculating one twelfth of annual license fees specified in its distribution contracts. The transaction price allocated to remaining performance obligations within these fixed price or minimum guarantee distribution revenue contracts was $1.5 billion as of March 31, 2020 and is expected to be recognized over the next 5 years. The Company's content licensing contracts and sports sublicensing deals are licenses of functional intellectual property. Certain of these arrangements extend beyond one year. The transaction price allocated to remaining performance obligations on these long-term contracts was $744 million as of March 31, 2020 and is expected to be recognized over the next 5 years. The Company's brand licensing contracts are licenses of symbolic intellectual property. Certain of these arrangements extend beyond one year. The transaction price allocated to remaining performance obligations on these long-term contracts was $126 million as of March 31, 2020 and is expected to be recognized over the next 12 years. The value of unsatisfied performance obligations disclosed above does not include: (i) contracts involving variable consideration for which revenues are recognized in accordance with the usage-based royalty exception, and (ii) contracts with an original expected length of one year or less, such as advertising contracts.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The following table reconciles the U.S. federal statutory income tax rate to the Company's effective income tax rate. Three Months Ended March 31, 2020 2019 U.S. federal statutory income tax provision $ 113 21 % $ 120 21 % State and local income taxes, net of federal tax benefit 14 3 % 20 4 % Effect of foreign operations 27 5 % 11 2 % Change in uncertain tax positions 4 — % 6 1 % Noncontrolling interest adjustment (10) (2) % (12) (2) % Deferred tax adjustment (23) (4) % — — % Other, net 5 1 % 8 1 % Income tax expense $ 130 24 % $ 153 27 % Income tax expense was $130 million and $153 million, and our effective tax rate was 24% and 27%, for the three months ended March 31, 2020 and March 31, 2019, respectively. The decrease in income tax expense for the three months ended March 31, 2020 was primarily attributable to a decrease in income and a deferred tax adjustment in the U.S. The decrease was partially offset by the effect of foreign operations, which included taxation and allocation of income and losses among multiple foreign jurisdictions and establishment of a valuation allowance for certain deferred tax assets. The Company and its subsidiaries file income tax returns in the U.S. and various state and foreign jurisdictions. The Internal Revenue Service recently completed audit procedures for its 2008 to 2011 tax years, the results of which should be finalized in the coming year. The Company is currently under audit by the Internal Revenue Service for its 2012 to 2015 consolidated federal income tax returns. It is difficult to predict the final outcome or timing of resolution of any particular tax matter. Accordingly, the impact of these audits on any of the reserves for uncertain tax positions cannot currently be determined. With few exceptions, the Company is no longer subject to audit by any jurisdiction for years prior to 2006. The Company's reserves for uncertain tax positions as of March 31, 2020 and December 31, 2019 totaled $380 million and $375 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 $129 million within the next twelve months as a result of ongoing audits, lapses of statutes of limitations or regulatory developments. As of March 31, 2020 and December 31, 2019, the Company had accrued approximately $63 million and $58 million, respectively, of total interest and penalties payable related to unrecognized tax benefits. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense.

Commitments and Contingencies Disclosure [Abstract]
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 finance leases, employment contracts, arrangements to purchase various goods and services, and future funding commitments to equity method investees. Contingencies Put Rights The Company has granted put rights to certain consolidated subsidiaries, which may be exercised beginning in 2021. 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 future consolidated financial position, future results of operations or cash flows. During the three months ended March 31, 2019, a withholding tax claim recorded as part of the provisional Scripps Networks purchase accounting was settled with a portion of the claim being resolved subsequent to the measurement period, which resulted in a reversal of the remaining accrual and a reduction in selling, general, and administrative expense of $29 million. Guarantees There were no guarantees recorded under ASC 460 as of March 31, 2020 and December 31, 2019. 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 March 31, 2020 and December 31, 2019.

Reportable Segments

Reportable Segments	3 Months Ended

Segment Reporting [Abstract]
Reportable Segments	REPORTABLE SEGMENTSThe Company’s operating segments are determined based on: (i) financial information reviewed by its chief operating decision maker ("CODM"), the Chief Executive Officer ("CEO"), (ii) internal management and related reporting structure, and (iii) the basis upon which the CEO makes resource allocation decisions. 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. 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) employee share-based compensation, (ii) depreciation and amortization, (iii) restructuring and other charges, (iv) certain impairment charges, (v) gains and losses on business and asset dispositions, (vi) certain inter-segment eliminations related to production studios, (vii) third-party transaction costs directly related to the acquisition and integration of Scripps Networks and other transactions, and (viii) other items impacting comparability, such as the non-cash settlement of a withholding tax claim. (See Note 16.) 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 share-based compensation, restructuring and other charges, certain impairment charges, gains and losses on business and asset dispositions and acquisition and integration costs from the calculation of Adjusted OIBDA due to their impact on comparability between periods. The Company also excludes depreciation of fixed assets and amortization of intangible assets, as these amounts do not represent cash payments in the current reporting period. Certain corporate expenses and inter-segment eliminations related to production studios are excluded from segment results to enable executive management to evaluate segment performance based upon the decisions of segment executives. Total 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 U.S. GAAP. The tables below present summarized financial information for each of the Company’s reportable segments, other, and corporate and inter-segment eliminations (in millions).

Subsequent Events	SUBSEQUENT EVENTS Amendment to Revolving Credit Facility To preserve flexibility in the current environment, the Company amended certain provisions of the its revolving credit facility subsequent to March 31, 2020. On April 30, 2020, DCL, as borrower, certain wholly owned subsidiaries of DCL party thereto as designated borrowers, Discovery, as guarantor, the lenders party thereto and Bank of America, N.A., as administrative agent (in its capacity as administrative agent, the “Administrative Agent”), entered into Amendment No. 2 to the Amended and Restated Credit Agreement (“Amendment No. 2”), which amended the Amended and Restated Credit Agreement, dated February 4, 2016, which was previously amended by Amendment No. 1 to the Amended and Restated Credit Agreement, dated August 11, 2017, (collectively, the “Existing Credit Agreement”). Amendment No. 2 modifies certain terms of the Existing Credit Agreement, including the following: The financial covenants were modified to reset the Maximum Consolidated Leverage Ratio as set forth below: Measurement Period Ending Maximum Consolidated Leverage Ratio March 31, 2020 and June 30, 2020 5.00:1.00 September 30, 2020 through March 31, 2021 5.50:1.00 June 30, 2021 5.00:1.00 September 30, 2021 and thereafter 4.50:1.00 In addition, the restricted payments covenant was modified to add a limitation on restricted payments made in cash unless after giving pro forma effect thereto the consolidated leverage ratio is less than or equal to 4.50:1.00. Finally, the minimum LIBOR rate and the minimum base rate was each increased from 0% to 0.50% per annum. In connection with the execution of Amendment No. 2, DCL paid customary arranger and lender consent fees and fees and expenses of Bank of America, N.A., in its capacity as administrative agent as well as other third party fees. The Company is currently evaluating the accounting implications of lender and other third party fees related to Amendment No. 2 on its consolidated financial position, cash flows and results of operations.

Condensed Consolidating Financial Statements	CONDENSED CONSOLIDATING FINANCIAL STATEMENTS Overview As of March 31, 2020 and December 31, 2019, most of the Company's 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 7.) Each of the Company, DCL and/or Discovery Communications Holding LLC (“DCH”) (collectively the “Issuers”) has the ability to conduct registered offerings of debt securities. 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) Scripps Networks, (iii) DCH, (iv) DCL, (v) the non-guarantor subsidiaries of DCL, (vi) the non-guarantor subsidiaries of Discovery, which includes Discovery Holding Company ("DHC") and Scripps Networks on a combined basis, and (vii) reclassifications and eliminations necessary to arrive at the consolidated financial statement balances for 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, non-Scripps U.S. and international networks, 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 along with the operations of Scripps Networks. The Company and Scripps Networks fully and unconditionally guarantee all of Discovery's senior notes on an unsecured basis, except for the $135 million un-exchanged Scripps Networks Senior Notes. (See Note 7.) 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, Scripps Networks, and the other non-guarantor subsidiaries of the Company, including the non-guarantor subsidiaries of Scripps Networks, (ii) DCH’s interest in DCL, and (iii) DCL’s interests in the non-guarantor subsidiaries of DCL. Intercompany 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 below should be read in conjunction with the consolidated financial statements of the Company.

Description of Business and Basis of Presentation (Policies)	3 Months Ended
	Mar. 31, 2020
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Discovery and its majority-owned subsidiaries in which a controlling interest is maintained, including variable interest entities ("VIE") for which the Company is the primary beneficiary. Inter-company accounts and transactions between consolidated entities have been eliminated.
Basis of Presentation	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, 2019 (the “2019 Form 10-K”).
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from these estimates. Significant estimates and judgments inherent in the preparation of the consolidated financial statements include accounting for asset impairments, revenue recognition, estimated credit losses, content rights, leases, depreciation and amortization, business combinations, share-based compensation, defined benefit plans, income taxes, other financial instruments, contingencies, and the determination of whether the Company should consolidate certain entities. Impact of COVID-19 On March 11, 2020, the World Health Organization declared the current novel coronavirus (“COVID-19”) outbreak to be a global pandemic. COVID-19 continues to spread throughout the world, and the duration and severity of its effects and economic disruption are currently unknown. In response to this declaration and the rapid spread of COVID-19, the United States and other countries throughout the world have imposed varying degrees of restrictions on social and commercial activity in an effort to slow the spread of the illness. These measures have begun to have a significant adverse impact upon many sectors of the economy, including the media industry. The Company is closely monitoring the impact of COVID-19 on all aspects of its business and geographies, including how it will impact its customers, employees, suppliers, vendors, distribution and advertising partners, production facilities, and various third parties. While the Company did not incur significant disruptions during the three months ended March 31, 2020, the Company has taken certain steps to mitigate the adverse impacts on and risks to the Company's business in light of the pandemic. The Company is unable to predict the full impact that COVID-19 will have on its financial position, operating results, and cash flows due to numerous uncertainties and the speed with which the COVID-19 situation is developing. The extent to which COVID-19 impacts the Company’s results will depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of COVID-19 and the actions to contain the virus or treat its impact, among others. The Company’s consolidated financial statements presented herein reflect the latest estimates and assumptions made by management that affect the reported amounts of assets and liabilities and related disclosures as of the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. Actual results may differ significantly from these estimates and assumptions. The Company assessed goodwill, other intangibles, deferred tax assets, programming assets, and accounts receivable for recoverability based upon latest estimates and judgments with respect to expected future operating results, ultimate usage of content and latest expectations with respect to collectability. No asset impairments were recorded as of March 31, 2020, as the fair value of such assets exceeded their carrying value. However, due to significant uncertainty surrounding the situation, management’s judgment regarding this could change in the future. Finally, the effects of the pandemic may negatively impact the Company’s financial position, results of operations, and cash flows. However, the current level of uncertainty over the economic and operational impacts of COVID-19 means the related financial impact cannot be reasonably and fully estimated at this time. In response to the COVID-19 pandemic, during the first quarter of 2020, the Company pursued a number of cost savings initiatives that it believes will offset a portion of potential revenue losses and deferrals due to the impact of COVID-19, through the implementation of travel, marketing, production and other operating cost reductions. The Company also implemented remote work arrangements effective mid-March 2020 and to date, these arrangements have not materially affected our ability to maintain our business operations. Additionally, certain sporting events that the Company has rights to have been cancelled or postponed, thereby eliminating or deferring the related revenues and expenses. For example, on March 24, 2020, the International Olympic Committee and the Tokyo 2020 Organizing Committee agreed to postpone the Olympic Games to 2021. The Company expects that the postponement of the Olympic Games will shift Olympic-related revenues and defer significant expenses from fiscal year 2020 to fiscal year 2021. The Company generally relies on third-party production partners to produce its content, and these third-party production partners were forced to shut down during the first quarter of 2020 due to COVID-19. The Company continues to monitor customer and consumer demands by employing innovative production and programming strategies, including content filmed by our on-air talent and seeking viewer feedback on which content to air. We intend to continue to adapt our plans as needed to drive our business and meet our obligations during the COVID-19 situation. In addition, the Company has implemented several measures that the Company believes will preserve sufficient liquidity in the near term. As described further in Note 7, during March 2020, the Company drew down $500 million under its $2.5 billion revolving credit facility to increase its cash position and maximize flexibility in light of the current uncertainty surrounding the impact of COVID-19. The Company has upcoming corporate debt maturities in June 2020 of $600 million and in June 2021 of $640 million. Subsequent to the three months ended March 31, 2020, the Company entered into an amendment to its revolving credit facility (See Note 19.) Finally, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020 in the United States. The CARES Act provides numerous tax provisions and other stimulus measures, including temporary changes regarding the prior and future utilization of net operating losses, temporary changes to the prior and future limitations on interest deductions, temporary suspension of certain payment requirements for the employer portion of Social Security taxes, technical corrections from prior tax legislation for tax depreciation of certain qualified improvement property, and the creation of certain refundable employee retention credits. As of March 31, 2020, the Company does not expect the CARES Act to have a material effect on its financial position and results of operations. The Company continues to monitor other relief measures taken by the U.S. and other governments around the world.
Accounting and Reporting Pronouncements Adopted and Not Yet Adopted	Accounting and Reporting Pronouncements Adopted Content In March 2019, the Financial Standards Accounting Board ("FASB") issued Accounting Standards Update ("ASU") 2019-02, which generally aligns the accounting for production costs of episodic television series with the accounting for production costs of films. In addition, ASU 2019-02 modifies certain aspects of the capitalization, impairment, presentation and disclosure requirements in Accounting Standards Codification (“ASC”) 926-20 and the impairment, presentation and disclosure requirements in ASC 920-350. The Company adopted this ASU on January 1, 2020 and will apply the provisions prospectively. In connection with this adoption, the Company elected to treat all content rights and prepaid license fees as a noncurrent asset, with the exception of content acquired with an initial license period of 12 months or less and prepaid sports rights expected to air within 12 months. As of March 31, 2020 and December 31, 2019, $89 million and $579 million, respectively, of content rights and prepaid license fees were reflected as a current asset. The Company determined that most of its content is exploited as part of film groups. For such content assets, the unit of account for the impairment assessment is the respective film group. There was no material impact to the Consolidated Statements of Operations or the Consolidated Statements of Cash Flows. (See Note 5.) Goodwill In January 2017, the FASB issued ASU 2017-04, which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the former two-step goodwill impairment test and eliminating the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. Therefore, an entity will recognize impairment charges for the amount by which the carrying amount exceeds the reporting unit's fair value not to exceed the amount of goodwill recorded for that reporting unit. Goodwill impairment will no longer be measured as the excess of the carrying amount of goodwill over its implied fair value determined by assigning the fair value of a reporting unit to all of its assets and liabilities as if it had been acquired in a business combination. The Company adopted this ASU on January 1, 2020 and will apply the provisions prospectively to future goodwill impairment tests. Financial Instruments - Credit Losses In June 2016, the FASB issued ASU 2016-13, which changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans and replaces the incurred loss methodology with a new, forward-looking “expected loss” model that considers the risk of loss over the asset’s contractual life, even if remote, historical experience, current conditions, and reasonable and supportable forecasts of future relevant events. The Company adopted this ASU on January 1, 2020 using a modified retrospective approach and recorded a noncash cumulative effect of adoption as an increase to retained earnings of $2 million to align our credit loss methodology with the new standard. (See Note 10.) Accounting and Reporting Pronouncements Not Yet Adopted LIBOR In March 2020, the FASB issued ASU 2020-04, which provides temporary optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships, and other transactions if certain criteria are met in order to ease the potential accounting and financial reporting burden associated with the expected market transition away from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The ASU is effective as of March 12, 2020 through December 31, 2022. The Company is currently assessing the impact ASU 2020-04 will have on its consolidated financial statements and related disclosures, if elected.
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.
Derivatives	The Company uses derivative financial instruments to modify its exposure to market risks from changes in foreign currency exchange rates and interest rates. The Company does not enter into or hold derivative financial instruments for speculative trading purposes.
Segment Reporting	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.

Fair Value Disclosures [Abstract]
Summary of Fair Value Categories	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.
