Secondly, iTunes has a new iTunes U, a section of iTunes where you can download lectures from universities across the country. I discovered that UC Berkeley offers three free geography classes this semester - 1) Geography 10 - World Regions, People, and States, 2) Geography 110 - Economic Geography of the Industrial World, and 3) Geography 130 - Natural Resources and Population. To subscribe, go to iTunes U on iTunes, select UC Berkeley, and select Social Sciences and you'll find the geography courses there. Enjoy! Please post to the comments below if you're aware of any other great geography-themed podcasts.
