Significant Accounting Policies [Abstract]
Basis of Consolidation Policy	The consolidated financial statements include all of the assets, liabilities, revenues, expenses and cash flows of TWC and all entities in which TWC has a controlling voting interest. In accordance with authoritative guidance issued by the Financial Accounting Standards Board (“FASB”) related to the consolidation of variable interest entities, the consolidated financial statements include the results of the Time Warner Entertainment-Advance/Newhouse Partnership (“TWE-A/N”) only for the TWE-A/N cable systems that are controlled by TWC and for which TWC holds an economic interest. Intercompany accounts and transactions between consolidated companies have been eliminated in consolidation.
