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 AMC Networks Inc. ("AMC Networks") and its subsidiaries (collectively referred to as the "Company," "we," "us," or "our") own and operate entertainment businesses and assets. Segment Reporting Changes In the first quarter of 2021, the Company changed its presentation of operating segments, reflecting a reorganized operating structure focused on a multi-platform distribution approach to content monetization. The Company's streaming services and IFC Films, previously included in the International and Other segment, are now included within Domestic Operations (formerly referred to as the National Networks segment). In addition, certain corporate overhead costs will no longer be allocated to the operating segments. Operating segment information for the prior periods has been recast to reflect these changes. The new reporting structure consists of the following two operating segments: •Domestic Operations: Includes activities of our five national programming networks, our streaming services, AMC Studios operation, IFC Films and AMC Broadcasting & Technology. Our national programming networks are AMC, WE tv, BBC AMERICA, IFC, and SundanceTV. Our streaming services consist of our targeted subscription streaming services (Acorn TV, Shudder, Sundance Now, and ALLBLK), AMC+ and other streaming initiatives. Our AMC Studios operation produces original programming for our programming networks and also licenses such programming worldwide. IFC Films is our film distribution business and AMC Networks Broadcasting & Technology is our technical services business, which primarily services most of the national programming networks. •International and Other: Includes AMC Networks International ("AMCNI"), our international programming businesses consisting of a portfolio of channels around the world and 25/7 Media (formerly Levity), our production services business. See Note 4 relating to the spin-off of the Levity comedy venues business. Basis of Presentation Principles of Consolidation The consolidated financial statements include the accounts of AMC Networks and its subsidiaries in which a controlling voting interest is maintained or variable interest entities ("VIEs") in which the Company has determined it is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation. Investments in business entities in which the Company lacks control but does have the ability to exercise significant influence over operating and financial policies are accounted for using the equity method of accounting. Unaudited Interim Financial Statements These condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and Article 10 of Regulation S-X of the Securities and Exchange Commission ("SEC"), and should be read in conjunction with the Company's consolidated financial statements and notes thereto for the year ended December 31, 2020 contained in the Company's Annual Report on Form 10-K ("2020 Form 10-K") filed with the SEC. The condensed consolidated financial statements presented in this Quarterly Report on Form 10-Q are unaudited; however, in the opinion of management, such financial statements reflect all adjustments, consisting solely of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. The results of operations for interim periods are not necessarily indicative of the results that might be expected for future interim periods or for the full year ending December 31, 2021. Risks and Uncertainties The Company continues to monitor the ongoing impact of the COVID-19 pandemic on all aspects of its business. The Company cannot reasonably predict the ultimate impact of the COVID-19 pandemic, including the extent of any adverse impact on our business, results of operations and financial condition, which will depend on, among other things, the duration and spread of the pandemic, the impact of governmental regulations that have been, and may continue to be, imposed in response to the pandemic, the effectiveness of actions taken to contain or mitigate the outbreak, the availability, safety and efficacy of vaccines, and global economic conditions. The Company does not expect the COVID-19 pandemic and its related economic impact to affect its liquidity position or its ongoing ability to meet the covenants in its debt instruments. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements; and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Significant estimates and judgments inherent in the preparation of the consolidated financial statements include the useful lives and methodologies used to amortize and assess recoverability of program rights, the estimated useful lives of intangible assets and the valuation and recoverability of goodwill and intangible assets. Recently Adopted Accounting Standards Effective January 1, 2021, the Company adopted Financial Accounting Standard Board (“FASB”) Accounting Standards Update (“ASU”) 2019-12, Simplifying the Accounting for Income Taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 - Income Taxes. The adoption of the standard did not have a material effect on its consolidated financial statements.
