Take a guess, what’s the biggest university in the world? If we counted virtual, unaccredited universities, then iTunes U would probably qualify. Apple is no stranger to mind-blowing numbers when it comes to downloads — I have lost track of how many billions of songs in iTunes, and how many apps in the App Store. Add another feather to their cap : iTunes U has reached 100 million downloads.

What is iTunes U?

iTunes U is a free component on the iTunes Store, open to anyone with an interest in learning. iTunes U has over 200,000 educational audio and video files from over 175 higher education organizations including Princeton University, UCLA, Harvard University, MIT, NYU Medical School, Oxford, Cambridge, Georgetown, DePaul, Duke, and Yale University.

The range and depth of the content available is really amazing, and sometimes you get these gems like the Zombies! The Living Dead in Literature course.
