Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation, Policy	Principles of Consolidation The consolidated financial statements include the accounts of AMC Networks and its majority owned or controlled subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates, Policy	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("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 derivative assets and liabilities, certain stock compensation awards, the useful lives and methodologies used to amortize and assess recoverability of program rights, the estimated useful lives of intangible assets, valuation and recoverability of goodwill and intangible assets and income tax assets and liabilities.
