One of the great joys of iTunes is the way it gives you access, in the iTunes Store, to thousands of free amateur and professional podcasts (basically, downloadable radio shows).

Here, you can choose to sync all podcast episodes, selected shows, all unplayed episodes—or just a certain number of episodes per sync. Individual checkboxes let you choose which podcast series get to come along for the ride, so you can sync to suit your mood at the time.
