Apple has announced that iTunes U downloads have surpassed the 300 million mark. Launched just over three years ago, iTunes U offers users public access to content from learning institutions such as Harvard, MIT, Cambridge, Oxford, University of Melbourne and Université de Montréal. “iTunes U makes it easy for people to discover and learn with content from many of the world’s top institutions,” said Eddy Cue, Apple’s vice president of Internet Services. “With such a wide selection of educational material, we’re providing iTunes users with an incredible way to learn on their computer, iPhone, iPod or iPad.” According to Apple, over 800 universities worldwide have active iTunes U sites, and nearly half of these institutions distribute their content publicly. Overall, iTunes U hosts more than 350,000 audio and video files from educational institutions around the globe.
