Margaret Gould Stewart: How YouTube thinks about copyright

YouTube receives a hundred years of video each day. Every single one of these videos is determined if it matches any other type of video such as a TV show, music video, movie, etc. These videos have all copyright policies, either allowing or not allowing the video to be posted. The vastness of the files they must check to see of there is a match and the amount of videos being posted daily is an incredible amount of information, and youtube processes all of this information extremely fast. By allowing people to post other people's videos, the owner's of the videos can get free publicity, new audiences, revenue, and  recognition.
