University of California, Berkeley, will deliver educational content, including course lectures, through Google Video. Berkeley even has a special page that features some of the videos, including a Sergey Brin lecture from 2005. "Coursecasting is a growing trend in educational technology, enabling students and the general public to download audio and video recordings of class lectures to their computers and portable media devices. As with UC Berkeley's agreement to deliver podcasts through Apple Computer's iTunes U, the content made available via Google Video will consist mostly of recorded course lectures and special campus events," mentions the press release.
I think it's a good idea to spread knowledge through mainstream channels like Google Video, and more universities should follow Berkeley's path.
