The Xbox Live Marketplace team has added free Comic-Con 2008 videos to the Zune Marketplace. The event, which ran from July 24-27 in San Diego, California, is a huge convention for fans of comic books, sci-fi, fantasy, anime, horror, and other related arts spanning all genres from books to TV to film. Once devoted just to comics, today’s convention has everything from toys to video games to panels featuring Hollywood actors and producers talking about their latest big movie and screening trailers of highly anticipated films. Since not everyone can attend this event, the next best thing is to download free videos from Comic-Con 2008. All you need is the Zune software – if you don’t have a Zune, you can always just watch them on your PC.
