''American Dad!'' is the second cartoon sitcom from the creator of ''WesternAnimation/FamilyGuy'', Creator/SethMacFarlane, along with Matt Weitzman and Mike Barker. A pillory of American ultra conservatism played out on UsefulNotes/RupertMurdoch's [[Creator/{{Fox}} network]], it follows the daily life of [[CharacterDevelopment initially-paranoid]] and extremely patriotic CIA agent Stan Smith, his over-protective wife Francine, nerdish teenage son Steve, and liberal and rebellious teenage daughter Hayley. The pilot episode explains that, on a mission, Stan uncovered a runaway talking alien named Roger, who lives in the family's attic for protection from getting turned in to the federal agency, until he adapted more to the outside world and became more outgoing through the use of various disguises later in the series. They also have a talking German goldfish named Klaus, who used to be a human.

Early in its run, ''American Dad!'' was viewed as a clone of ''Family Guy'', but it quickly outgrew this reputation and developed its own identity. It has accomplished this largely by emphasizing story and character development and not including most of ''Family Guy'''s trademark shticks, like the {{cutaway gag}}s, {{flashback twist}}s, {{big lipped alligator moment}}s, {{overly long gag}}s, and its excessive use of {{take that}}s (though the occasional one does occur), making it a show that even detractors of Creator/SethMacFarlane's works could enjoy. Initially, the show relied on caricatures of political personalities, as well as some of the more visible and controversial aspects of the right wing's policies and ideologies (although granted, usually the [[StrawCharacter Strawman Political]] version of said policies) and was, in [=MacFarlane=]'s words, "...going to be the next ''Series/AllInTheFamily''". Over time, however, as the characters' personalities began to be fleshed out, the show became less and less political in nature, to the point where only a small portion of the episodes featured politics as an active theme (curiously, as this was taking place, ''Family Guy'' was steadily becoming ''more'' political).

The show began to [[GrowingTheBeard grow its beard]] in the two-part episode "Stan of Arabia"[[note]]Whose part 2 scriptwriters were ''Series/HowIMetYourMother'' creators Carter Bays and Craig Thomas[[/note]] midway through the second season. Since then the plots have become more eccentric and arguably more entertaining as a result. The show has shown a willingness to experiment with unconventional storytelling techniques, such as "Star Trek", in which Steve's brief success as a children's author is told in the style of a 1940s FilmNoir story, and "Of Ice and Men", which is related as a ''[[Film/ThePrincessBride Princess Bride]]''-style bedtime story told by a years older (and now human) Klaus to his young grandson. The quality varies wildly from episode to episode, but the risks the writers take often lead to stories laced with snappy dialogue and strong performances from the voice actors.

Because of low ratings and FOX's plans to revert the Sunday night line-up from "Animation Domination" to "Sunday Funday"[[note]]which includes ''WesternAnimation/BobsBurgers'', ''WesternAnimation/TheSimpsons'', ''Series/BrooklynNineNine'', ''WesternAnimation/FamilyGuy'', and ''Series/{{Mulaney}}''. As of 2016, this line-up has changed to include the Mark Hentemann-created animated series ''Bordertown'', ''Cooper Barrett's Guide to Life'', and Creator/WillForte's ''TheLastManOnEarth'' and exclude ''Mulaney'', since that show was canceled[[/note]], ''American Dad'' has been canceled on FOX (but not before airing three leftover season 10 episodes as a separate mini 11th season on September 14th and September 21st 2014). Creator/{{TBS}} picked up the show for a 15-episode 12th season, which premiered on October 20th, 2014. Shortly after its cable premiere, the show was renewed for a 22-episode 13th season which premiered on January 25th, 2016. Shortly after Season 13 ended, it was then renewed for a 14th and 15th season both of which are also 22 episodes long with the former premiering on November 7th, 2016 and the latter on December 25th, 2017. Shortly after the Season 15 premiere, the show was renewed for a 16th and 17th season meaning that the show will run into at least 2020. The new episodes are said to be "more of the same, except on a new channel", though some longtime fans would argue that the show has gone through a [[SeasonalRot noticeable decline in quality]] since the switch that only gets worse with each new TBS season.
