PAX is Penny Arcade Expo, a gamer festival. Lots of companies show off their games there. For at least the last few years they haven't allowed companies to have booth babes, who are generally just there to look pretty and draw crowds, as it is fairly demeaning and makes some people uncomfortable. In order to determine how people actually felt about the ban, they decided to hold a poll. These are the results of the poll.
PAX is the Penny Arcade Expo. Think of it as E3 for the public.
