The University of California Berkeley has run a trial program this past semester that makes webcasts available from around 30 courses. (MIT also has had some course videos and other material available for some time.) They also have special lectures and events available here. The courses range from Art 32, “Foundations of American Cyberculture”, to EE 240, “Advanced Analog Integrated Circuits”, to Psych 130, “Clinical Psychology”. There is one philosophy course – Phil 7, “Existentialism in Literature and Film” by Hubert Dreyfus. His course has 27 lectures; each appears to be a little over one hour. Video is available for many of courses, but not Dreyfus’s.
