Sumner Redstone has become the new Barry Diller when it comes to candid public comments. The Viacom chairman's interview with Charlie Rose on Wednesday will be getting lots of play today, especially the part about losing MySpace to, of all people, Rupert Murdoch. "It was a humiliating experience," he said. Redstone claims that before Murdoch got interested, MySpace was ready to be purchased for $500 million - and Viacom CEO Tom Freston didn't grab it. Now, of course, he's the ex-CEO. Murdoch's News Corp. wound up buying MySpace, then based in Santa Monica, for $580 million. Redstone claims it's now worth $1.5 billion (sounds quite high compared with other estimates). Redstone said Viacom isn't interested in another social networking site, Facebook, because the price is too high. He was non-commital about YouTube.
