The year Internext was upstairs and AEE was down stairs in the Sands convention center, I want to say 2006, felt like the show killer for me. The floor was dead, everyone was at AEE. Ron Jeremy stopped by the booth to say how nice it was to come up stairs and be able to get away from everyone
It was never the same after that. I'm sure there were other factors, but for whatever reason that stands out in my mind as the big drop off point for that show.
