Apple's iTunes U, an initiative encouraging schools to offer print, audio and video downloads of their eduction programs almost entirely free to the public, has hit a new milestone of 600 million downloads. The program was unveiled in early 2007, but according to Apple's figures obtained by The Loop, half of those downloads have occurred over the last year.
Apple noted hitting a milestone of 300,000 downloads last August, meaning the service has snowballed in growth since.
Nearly a third (30 percent) of iTunes U traffic now originates from iOS devices. The service, available worldwide in 123 countries, also counts 60 percent of its users as being outside the US.
