Podcasting is a new way of delivering content on the internet. Podcast software like iTunes automatically download the content to your machine when you subscribe to a site - no need for constant checking! However, users would still have to know where to go to find the sites they want to subscribe to, which isn't always an easy thing.

Enter iTunes U

iTunes U is a service offered by Apple that allows universities to create a special area of the popular iTunes interface where users can find and download content specific to that university, making it easier to search for your content than ever before. And the even better part - all of it is free!
