Adventure Time

Ward's creation is based on his 2007 short film that aired on Nicktoons as a pilot on Frederator's Random! Cartoons. After the short became a viral hit on the Internet, Nickelodeon's executives passed on its option before Cartoon Network commissioned a full-length series from Fred Seibert and Ward, which was previewed on March 11, 2010. The same year, the series premiered on Cartoon Network on April 5, and it ended its eight-year run on September 3, 2018. The series has since been succeeded by several spin-offs and follow-up shows, starting with the Adventure Time: Distant Lands specials in 2020.

The series drew inspiration from a variety of sources, including the fantasy role-playing game Dungeons & Dragons and video games. It was produced using hand-drawn animation; action and dialogue for episodes were decided by storyboard artists based on rough outlines. Because each episode took roughly eight to nine months to complete, multiple episodes were worked on concurrently. The cast members recorded their lines in group recordings, and the series regularly employed guest actors for minor and recurring characters. Each episode runs for about eleven minutes; pairs of episodes are often telecast to fill half-hour program slots.

Adventure Time was a ratings success for Cartoon Network, with some of its episodes attracting over three million viewers. It has been praised for its originality and worldbuilding. The show won eight Primetime Emmy Awards, a Peabody Award, three Annie Awards, two British Academy Children's Awards, a Motion Picture Sound Editors Award, and a Kerrang! Award. The series has also been nominated for three Critics' Choice Television Awards, two Annecy Festival Awards, a TCA Award, and a Sundance Film Festival Award, among others. Of the many comic book spin-offs based on the series, one received an Eisner Award and two Harvey Awards. It has also spawned various forms of licensed merchandise, including books, video games and clothing.
