The first season of AMC’s The Walking Dead appeared on Netflix’s instant streaming service today. According The Hollywood Reporter, AMC Networks has signed an exclusive multi-year streaming deal with Netflix for all of its programming. Netflix is already streaming AMC’s Mad Men and Breaking Bad. The new deal will include shows that air on the AMC, IFC, Sundance, and WEtv channels. New AMC Network content will become available on Netflix one year from its on air debut–meaning The Walking Dead: Season 2 should begin streaming on Netflix next October 2012.
