Sumner Redstone, never shy about shaking out the family laundry for the world to see, kept going after his daughter Shari today - the latest bit of nastiness coming in a faxed letter for Forbes' Robert Lenzner. Redstone reiterates his desire to have the board of Viacom and CBS select his successor as opposed to anointing Shari - even though he all but anointed Shari a couple of years back. Redstone says he would consider buying out Shari's 20 percent stake of National Amusements, a private company that owns movie theaters and has voting control of Viacom and CBS. But the price needs to be acceptable, Redstone adds. "It must be remembered that I gave to my children their stock; and it is I, with little or no contribution on their part, who built these great media companies with the help of the boards of both companies," he writes Lenzner. And I thought the Bancrofts were strange.
