Penny Arcade is a webcomic focused on video games and video game culture, written by Jerry Holkins and illustrated by Mike Krahulik. The comic debuted in 1998 on the website loonygames.com. Since then, Holkins and Krahulik have established their own site, which is typically updated with a new comic strip each Monday, Wednesday, and Friday. The comics are accompanied by regular updates on the site's blog. Penny Arcade is among the most popular and longest running gaming webcomics currently online, listed in 2010 as having 3.5 million readers. Holkins and Krahulik are among the few and first webcomic creators successful enough to make a living from their work. In addition to the comic, Holkins and Krahulik also created Child's Play, a children's charity; PAX, an annual gaming convention, and the episodic video game Penny Arcade Adventures: On the Rain-Slick Precipice of Darkness with Hothead Games and Zeboyd Games.
