The latest campus revolutionaries are the so-called edupunks — and their mission is to break up the ivory tower so everyone can pile into the classroom. MIT was the first university to heed the edupunk call: it started posting syllabi, course notes and videotaped lectures on ocw.mit.edu back in 2001. Harvard, Berkeley, Yale, Princeton and Stanford soon followed suit, with their own schemes for posting videos of their most popular courses. Now Academic Earth aggregates all this material so you can audit classes from the comfort of your computer.
