iTunes is being expanded in the US to include iTunes U, a free, hosted service for colleges and universities. It will provide easy access to educational content, including lectures and interviews 24 hours a day, 7 days a week.
Through iTunes U, users can download content to their Macs or PCs regardless of their location in the US. They can then listen to and view content on their Mac or PC or transfer that content to iPod for listening or viewing on the go.
It is possible that a similar service may be launched in the UK in the future.
