Organization, Consolidation and Presentation of Financial Statements [Abstract]

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, 2021 contained in the Company's Annual Report on Form 10-K ("2021 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, 2022.

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.

Reclassifications

Certain reclassifications were made to the prior period amounts to conform to the current period presentation.

Program Rights

The Company periodically reviews the programming usefulness of its licensed and owned original program rights based on several factors, including expected future revenue generation from airings on the Company's networks and other exploitation opportunities, ratings, type and quality of program material, standards and practices, and fitness for exhibition through various forms of distribution. If it is determined that film or other program rights have limited, or no, future programming usefulness, the useful life is updated, which generally results in a write-off of the unamortized cost to technical and operating expenses in the consolidated statements of income.
