Apple released iTunes 8 this past Tuesday at the Let’s Rock media event. Alongside many new features such as a Genius Sidebar and Playlist creator, the return of NBC, and a new way to browse through your music, an ever-growing library of HD content has also been thrown into the mix.

Below is a list (via cnet) with links directly to iTunes of some of the free HD content that iTunes is offering. These are just the first episodes to the season for most of the shows, but some are definitely worth watching. And it wouldn’t hurt to give some HD downloads a test run.
Just make sure you have iTunes 8 installed. You can download it free of charge right here.
