YouTube EDU is a gateway to free educational video content

YouTube EDU contains hundreds of free video clips from each college and university’s YouTube channel, including lectures by well-known professors and scholars on a variety of subjects. Site visitors can browse through each of these channels individually, or search by the most viewed clips each month (or all time). Recently added content includes commencement speeches by President Barack Obama, talk-show host Oprah Winfrey, country singer Dolly Parton, and Google CEO Eric Schmidt; the science behind the movie "Angels and Demons," as revealed by Carnegie Mellon professor Manfred Paulini; and "Innovating on a Shoestring," from Harvard Business School.
