It's conventional wisdom that the popularity of Youtube, Google's video site, is built on pirated clips from hit TV shows such as The Colbert Report. Programming owned, in that instance, by Sumner Redstone's Viacom, which is suing Google for more than half the value set on Youtube by the search engine's acquisition, last year. After all, it wasn't as if the audience was really drawn by cat pratfalls and the other amateurish video hosted on the fabulously popular video sharing site. Nobody wants to watch that rubbish. Except they do. New data from Vidmeter, spotted by Henry Blodget , shows Viacom's jealously protected programming represented just 2% of videos viewed on Youtube. It's the accident-prone kittens that should be suing.
