In a new complaint filed Tuesday, National Amusements Inc. (NAI), CBS Corporation's parent company, now says that its vice chairwoman and CBS' majority stakeholder Shari Redstone advised Viacom's special committee that NAI no longer supported a merger — prior to CBS' lawsuit against Redstone and NAI that attempted to strip Redstone of her voting power. Why it matters: Today's statement solidifies what the media community has largely assumed for the past few weeks: the desire to merge CBS and Viacom is officially dead on both sides — not just from CBS' perspective. The bigger picture: It's the latest installment in the years-long saga of the power struggle between longtime CBS Chairman Les Moonves and Redstone that's intensified over the past few weeks. What they're saying: Go Deeper: The Wall Street Journal has a good profile on the tension between Moonves and Redstone.
