Maybe we've reached the TSSP (trade show saturation point), at least for telecom. Something to consider for those who see nothing but endless growth for the events biz.
Actually, I took that bird's-eye view photo of the show floor before the main conference session had let out, which was packed. There was more of a crowd there during lunch and the coffee breaks. It certainly felt busier at those times.
On the other hand, if you could have your meetings outside on a lovely day, rather than in an exhibit hall, what would you do?
I much preferred the view outside than in... looked a bit threadbare on the show floor...
