UC Berkeley is offering over 50 free courses available via iTunes (click here to launch their site in iTunes).

No matter where you live, you can access at no cost the very same courses attended by students paying full tuition. And, given the critical mass of courses being offered across a range of disciplines, you can put together your own personalized curriculum and expand your horizons on the fly. [OC Culture]

Courses include physics, history, psychology, geology, statistics, philosophy, economics, art and more.

This is an effective use of podcasting to promote higher education and the University. Berkeley is not the only University to offer free podcasts – either courses or lectures – but it does offer one of the largest collections.
