Academic Earth

http://academicearth.org/ is a website launched March 24, 2009, by Richard Ludlow which offers free online video from universities such as UC Berkley, UCLA, and Harvard.  On this website you can search the different subjects through the different university and pick the best lecture.  This is very useful to me because I could listen to lectures and learn information that I did not know. I think it would also be very useful to bussinesses.
