In Fall 2001, UC Berkeley's live and on-demand webcasts of select courses became a service of Educational Technology Services (ETS) in partnership with Information Systems and Technology (IS&T). This technology is based on the Berkeley Internet Broadcasting System (BIBS) developed by the Berkeley Multimedia Research Center (BMRC). Webcasts have now grown to include special campus events.
主要是CS和EE的课程,视频是随时更新的哦。
