News.com: “YouTube’s Filtering Issues Still Not Moot“:

A year ago Wednesday, Google CEO Eric Schmidt delighted an audience of TV and radio broadcasters when he promised to roll out a system that would mean the end of piracy at YouTube.com
“We are in the process of developing tools which are called ‘Claim Your Content,'” Schmidt said at the National Association of Broadcasters 2007 conference. “If people tell us this is a licensed copy, our computers will automatically detect that an illegal copy has been uploaded and then automatically delete it.”
Schmidt went on to say YouTube was “close to turning this (system) on” and once that happened, copyright violation at the site “becomes a moot issue.” But following through on that promise has proven a challenge.
