My Kid Is an Honor Student at iTunes U

Downloads from Apple’s iTunes U program topped the 300 million mark today–a formidable feat for a virtual insitution of higher learning that’s just three years old. Today, roughly 350,000 audio and video lectures (and commencement speeches) are available for download from some 800 universities, among them Harvard, Brown, Berkeley, Stanford, MIT and Oxford. And that list is growing quickly as universities in China, Japan, Mexico and Singapore join the initiative.

A nice little bit of back-to-school marketing for Apple (AAPL), which likely has an eye trained on education sales as the new school year begins.
