Comic-Con 2012 got underway yesterday, and some interesting bits of news have been filtering out. Digital comic sales boomed over the past year — something to be expected given the trend with ebooks and newspapers. But oddly, print comic sales are up as well, to the tune of 18%. At a Firefly panel, Joss Whedon spoke briefly about how the series would have ended if he could have done it on his own terms. "I don’t think I would have killed anybody," he said. TV shows are a strong theme this year, which much discussion around The Walking Dead and Game of Thrones. All in all, about 80 television programs are represented at Comic-Con. The show is also highlighting the recent trend away from strict superhero stories. "Image Comics is indeed banking on 'superhero-ed out' readers, not only with Kirkman's The Walking Dead, (Kirkman has been called the 'unofficial mayor of Comic-Con') but with books like the spy-fi The Activity. The title's second issue, out next week, was co-plotted with actual Navy SEALs."
