Comic-con International: San Diego 2006 proved that this gathering is becoming a must-attend event for more people every year. Convention veterans expect that official attendance figures will show this year's crowd surpassed last year's record-breaking turnout of 100,000 fans. So many fans showed up, in fact, that officials were forced to shut down online and onsite registration for a time on Friday and Saturday. With so many potential customers packed into one space, it's no wonder that traditional trade book publishers are taking notice. Random, Abrams and Scholastic were very much a presence on the exhibition floor and in the programming, while Warner Books had a (small) booth for the first time at Comic-con. Meanwhile, comics publishers were showing off their own books to a throng of media outlets, from blogs to national newspapers to network news shows. More proof (as if you didn't know) that San Diego Comic-con is not just for nerds anymore.
