Google "could do a better job" at preventing illegally copied video from appearing on its YouTube site, Peter Chernin, president and chief operating officer of News Corp, said in an interview with the Financial Times.

The comments by Mr Chernin, who oversees News Corp's MySpace social networking site, the second-biggest video-sharing destination after YouTube, come ahead of News Corp's launch this month of a site for professionally produced video, including its Fox shows and movies, with NBC Universal.
