Adventure Time is an American animated television series created by Pendleton Ward for Cartoon Network. 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 shape and size at will. Finn and Jake live in the post-apocalyptic Land of Ooo, where they interact with Princess Bubblegum (Hynden Walch), the Ice King (Tom Kenny), Marceline the Vampire Queen (Olivia Olson), BMO (Niki Yang), and others. The series is based on a 2007 short produced for Nicktoons and Frederator Studios' animation incubator series Random! Cartoons. After the short became a viral hit on the Internet, Cartoon Network commissioned a full-length series, which previewed on March 11, 2010, and officially premiered on April 5, 2010.
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 are decided by storyboarding artists. 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. On September 29, 2016, it was announced that the series would conclude in 2018, after the airing of its tenth season.§
Adventure Time has been a ratings success for Cartoon Network and some episodes have attracted over 3 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: seven Primetime Emmy Awards, a Peabody Award, three Annie Awards, two British Academy Children's Awards, a Motion Picture Sound Editors Award, a Pixel 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. Various forms of licensed merchandise, including books, video games and clothing, have been inspired by the series.
