When Holkins and Krahulik's first Penny Arcade web comic debuted on loonygames.com in 1998, they had no idea it was the start of a gaming empire. Since then, Penny Arcade has become one of the biggest sites in the industry, they've started a charity (Child's Play) and two conventions (PAX and PAX East) with thousands of attendants, and the comic has grown to reach an audience of 3.5 million.
