Today, Clicker.com comes out of beta and promises to become the complete guide to Internet Television. Currently, the site "contains more than 450,000 episodes, from over 6,000 shows, from over 1,200 networks, tens of thousands of movies, and 50,000 music videos from 20,000 artists." The content (all apparently legal) is generally supplied by other content providers, and then aggregated by Clicker. Although the content is often quite pop, you can find some university content (Berkeley, Yale, Princeton, Stanford, etc.) in the mix, much of it supplied by Academic Earth. Other quality content appears in the Art & Artists section here and the Documentary section here.
Thanks Denise for the tip.
