The Sci-Fi Channel knows it's got a good thing with Battlestar Galactica, and they also know their series is showing up on a lot of year-end best lists. So they are doing what they can to grab new viewers. The first season has been out on DVD for a bit ... the box also includes the mini-series that started the new version of the show. Now, midway through the second season, they've released the first ten episodes of Season Two on DVD, just in time for the second half of the second season to begin next month.
Meanwhile, they've put together a short (22 minutes if you download, 30 minutes if you watch on real TV with commercials) featurette that will get you up to speed on the show. You can wait for it to come on Sci-Fi Channel, or you can download it for free from iTunes. Apple doesn't tell you this, but if you download a teevee show from iTunes, you don't have to play it on an iPod, you can play it within iTunes itself ... even do a full-screen mode.
Since Battlestar Galactica is a great show, and since you probably aren't watching it, here's your chance to catch up.
