Google has launched new digital “watermarking” technology on YouTube in an attempt to stop copyrighted movies and TV programmes from appearing on the popular online video service.

Called YouTube Video Identification, the new technology has been in development for months with content partners including Time Warner and Disney.

Over six hours of video are uploaded onto YouTube every minute and since it was bought by Google last year for $1.65bn, the site has increasingly been targeted by media companies who accuse it of aiding people in breaching copyright.
