Reuters: Media investors are looking beyond the legal battle between the Redstone family and Viacom CEO Philippe Dauman, speculating that a deal for the $18 billion media giant could be on the horizon. The thinking is that if Dauman leaves, Viacom’s fate would be in play. Some investors said they want Viacom put up for sale in an open auction and believe suitors could include Discovery, AMC, Apple, Dish Network, and Verizon.
