Such universities as Duke, Yale, Cambridge, MIT and Oxford are leading the way, with more than 100,000 students enrolled in single iTunes U courses.

"It's inspiring to see what educators and students of all types are doing with iTunes U," said Apple's Eddy Cue in a press release. "With the incredible content offered on iTunes U, students can learn like never before; there are now iTunes U courses with more than 250,000 students enrolled in them, which is a phenomenal shift in the way we teach and learn."
