According to this news, Stanford University is debuting a project called "Stanford on iTunes", providing Stanford-related audio content via the iTunes Music Store:

Stanford on iTunes will provide alumni—as well as the general public—with a new and versatile way of staying connected to the university through downloads of faculty lectures, campus events, performances, book readings, music recorded by Stanford students and even podcasts of Stanford football games. (...) In addition to content targeted at alumni, the project includes audio related to academic courses exclusively for Stanford faculty and students. Instructors in Stanford's Introduction to the Humanities program began using the tool last spring to distribute course audio such as lectures, music and readings to students. (..) Also starting today, the general public will have free access to the same audio content at http://itunes.stanford.edu.
