Academic Earth, http://academicearth.org/, is a site to view free university lectures. Acorrding to the site, they have "thousands of video lectures from the world's top scholars." I found most to be lectures in Business, but it does include some lectures in a broad range of traditional university subjects. Some of these lectures include an entire semester's worth of video.
Universites represented include Berkely, Harvard, MIT, Princeton, Stanford and Yale.
