I don't know how many years this has been going on, but I'm sure it has been a long time. This show is huge. Download the map from
www.iaapa.org and you'll see what I'm talking about. I still haven't seen everything. Of course, if I spent less time sampling food, playing Ms. Pac-Man at Namco's booth, and marveling at the insanity that is the Slingshot, perhaps I'd cover more.
I'm not sure how many cities the show has been held in, but it must be held someplace that can accomodate it. Every square foot of this show is sold-out. I know it was in Orlando two years ago, and that's where it will be next year. Hmmm... I wonder what I can do in that area? ;)
I honestly don't think McCormick would be big enough. The World Congress Center really is that huge, and they're building another expansion as we speak. The company I work for in my day job puts on business-to-business trade shows, but none of them are this huge in scope. The dome is that "small" part of the show.
