Since launching in 1998, Penny Arcade has become one of the most popular and longest-running gaming webcomics. Holkins and Krahulik have parlayed that success into other ventures, like their charity Child's Play which delivers toys and video games to children in hospitals worldwide and the Penny Arcade Expo, or PAX, a festival for console, PC and tabletop game enthusiasts.
