New York Post: Theories abound on Wall Street about what conflicts might arise if either CBS or Viacom receives an outside bid in a post-Sumner Redstone world. Both companies are majority controlled by Redstone’s Boston-based National Amusements. The problem is that once Redstone’s reign ends, a trust takes over the running of National Amusements and that trust is staffed by members of both companies, with their own allegiances and interests.
