Adventure Time is an American fantasy animated[cm_simple_footnote id=1] television series created by Pendleton Ward for Cartoon Network[cm_simple_footnote id=2]. Produced by Frederator Studios and Cartoon Network Studios, the series follows the adventures of a boy named Finn (voiced by Jeremy Shada) and his best friend and adoptive brother Jake (John DiMaggio) – a dog with the magical power to change size and shape at will.

The series drew inspiration from a variety of sources, including the fantasy role-playing game Dungeons & Dragons[cm_simple_footnote id=3] and video games. It was produced using hand-drawn animation[cm_simple_footnote id=1]; action and dialogue for episodes are decided by storyboarding 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[cm_simple_footnote id=3] of episodes are often telecast to fill half-hour program slots. Cartoon Network[cm_simple_footnote id=2] announced that on September 29, 2016, the series would conclude in 2018, after the airing of its tenth season. The series finale aired on September 3, 2018. On October 23, 2019, four specials, collectively called Adventure Time: Distant Lands, were announced, which were released exclusively on HBO Max, on June 25, 2020 and November 19, 2020.

Adventure Time has been a ratings success for Cartoon Network[cm_simple_footnote id=2] and some episodes have attracted over three million viewers; despite being aimed primarily at children, it has developed a following among teenagers and adults. The show has received positive reviews from critics and won awards, including 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. The series has also spawned various forms of licensed merchandise, including books, video games and clothing.
