American Dad! is a satirical American cartoon series owned by Underdog Productions and Fuzzy Door Productions and produced in association with 20th Century Fox Television.

It was created by Seth MacFarlane, the creator of Family Guy, as well as two former Family Guy writers, Mike Barker and Matt Weitzman. The pilot episode aired in the United States on Fox on February 6, 2005, thirty minutes after the end of Super Bowl XXXIX; the regular series began May 1, 2005, after the season premiere of Family Guy. American Dad follows the events of CIA agent Stan Smith and his family. Unlike Family Guy, American Dad! rarely uses cutaway gags for its jokes, relying instead on situational humor and non sequiturs.

The series is currently in its fifth season, which premiered on September 27, 2009. It has been officially renewed for a sixth season; renewals are made ahead of time in order to facilitate the extensive production line of animated shows. The show was briefly put on hiatus in March 2010 to make way for the premiering live-action situation comedy Sons of Tucson. However, American Dad returned to Fox a month later after Sons of Tucson was put in hiatus. Since January 2008, Cartoon Network's Adult Swim program block reaired the show's syndication.
