If I might answer this one, I'd start by saying that places like YouTube have a very large audience. In terms of how we measure the public value the BBC creates, the reach we manage to achieve and the level of usage are among those key concerns. Doing deals with Google and YouTube is one way for us to get to audiences, particularly audiences who might be badly served by other ways of distributing BBC content.
The YouTube deal is one where we have three BBC channels on YouTube: a BBC channel, which is largely entertainment content; a news channel; and a BBC Worldwide channel, which focuses on the international aspect of our content. That content is provided in a BBC environment, whereas on YouTube ordinarily you'd see advertisements next to the content as it streams. When you click on the BBC channel you don't have the advertisements on the BBC public service offering. We are again sticking to our duty in our public service operations not to damage the commercial market unduly.
To give you a feel for the size of audiences we're talking about, the BBC recently did a deal with Bebo, the social networking site, where we provide short clips of BBC content, normally entertainment content, and that now is getting to 10.8 million U.K. unique monthly users. We are talking about a significant number of users.
Obviously it does have threats in terms of piracy and the context in which it can be seen occasionally. We do try, where possible in these deals, to make sure we retain control over the way in which the content is viewed.
