Bloomberg: AMC Networks, the cable network operator that owns shows including “The Walking Dead,” is said to be back in talks to acquire billionaire John Malone’s Starz, another TV programmer. The preliminary discussions may not result in an acquisition. An AMC-Starz deal would put Malone, who has driven cable and telephone industry consolidation in the past, in the thick of the action as film and TV companies weigh mergers. A combined AMC Networks and Starz would gain leverage in negotiating fees from pay-TV carriers.
