If you believe Trent Reznor and a good chunk of the music industry, Google (particularly YouTube) is a giant piracy machine -- it's allegedly doing little to block stolen content, and knowingly profits from it. Google isn't having any of that talk, though. The search firm just published an updated report detailing its anti-piracy efforts, and it maintains that it's doing a lot to fight bootleggers. It's adamant that its Content ID system (which can automatically claim copyrighted material for licensing or takedowns) does wonders for the media business. The technology has paid over $2 billion to copyright owners since launch, and about 98 percent of copyright action uses it -- just 2 percent comes down to formal copyright removal notices.
