If you haven’t noticed yet, the Zune Marketplace has some free TV shows that you can download on your Zune. I’m sure it’s a promotional thing, so they probably won’t be free for too much longer. I was able to download an episode of The Office, Battlestar Galactica, and Heroes. I’m not a big fan of The Office, but hey, it’s free and you shouldn’t look a gift horse in the mouth! 🙂
Update: BTW, there are actually several videos you can download for free from the Zune Marketplace (not just the three I mentioned above). I scanned through all the available shows yesterday, and most of them had one free episode available for download. Also, the video podcasts (which are always free) had lots of new videos for download, so that is definitely worth checking out.
