Viacom is confirming a deal with video sharing site Joost to license the former's video content. Joost — run by Kazaa and Skype founders Niklas Zennstrom and Janus Friis — has already landed similar deals with Warner Bros. among others, but Viacom represents a big fish indeed. This after Viacom browbeat Google into pulling its content off Youtube when the two failed to reach their own deal. Google loses a potential cash cow by way of Viacom's general intransigence and overlord Sumner Redstone's barely concealed antipathy for Youtube. No telling if the recently in-housed Comedy Central material is part of the Joost deal, and that's probably the cherry content of the whole lot.
