It was my understanding that YouTube isn't profitable; has there been any new data on this that I've missed? Lack of similar-sized competitors in the space would certainly indicate that the margins don't really stack up and you could make an argument that the aggressive foisting of their premium offering underscores that notion, but I don't know for sure. It'd be interesting to know more about operating a site of that nature at that scale but I don't suppose that sort of data will make it out any time soon!
