Comic-Con, Wow!, what a show! Two Hundred thousand plus attendees, half in costume, all looking for as many give-a-ways as they can cram into their oversized Comic-Con carry bags.  In addition to the trade show exhibits, all crammed with interactive games, celebrity signings and of course free t-shirts, the attendees attend panel discussions featuring their favorite movie, cable & broadcast TV shows, and famous character artists.   It was a typical retail, B-to-C show.  But what can the B-to-B producers learn from Comic-Con?  Plenty!
