Earlier this week at New York ComicCon, Marvel announced their intention to sell "In-Motion" comic books through the iTunes Store. According to Marvel, the In-Motion comics go beyond the paperback books with animated panels and voice-over work from popular actors. Sounds like something that could be a lot of fun on an iPod touch or iPhone.
Speaking of paperbacks, traditional paper versions will be made available following iTunes releases. As of this writing, there's no word on when these will be sold or for how much. I'll sacrifice some geek cred here and admit that I've never been a comic book fan. However, I do get behind attempts to expand artistic endeavors into new territory. Good luck to Marvel!
