PAX has pioneered a kind of event that honors the players, developers, and publishers of tabletop and video games. Founded by gamers, and in particular, the team behind Penny Arcade, who wanted to see a different kind of show, PAX has doubled in size each year until it hit venue capacities. At that point, they partnered with Reed Exhibitions and started bringing PAX to other cities around the world including Boston, San Antonio, and Melbourne, Australia.
Defining characteristics of the shows include an opening keynote speech from an industry insider, game-culture inspired concerts, panels on game topics, exhibitor booths from both independent and major game developers and publishers, a LAN party multiplayer, tabletop gaming tournaments, and video game freeplay areas.
