Apple has announced that downloads of iTunes U content have topped one billion. iTunes U doesn’t get much mainstream press, but it could be one of Apple’s most important projects, hosting over 2,500 courses (and thousands more private courses) from over 1,200 colleges and universities, plus another 1,200 K-12 schools and districts.
