Adventure Time is an American animated television series created by Pendleton Ward for Cartoon Network. The series follows the adventures of Finn (voiced by Jeremy Shada), a human boy, and his best friend and adoptive brother Jake (John DiMaggio), a dog with magical powers to change shape and grow and shrink at will. Finn and Jake live in the post-apocalyptic Land of Ooo. Throughout the series, they interact with the show's other main characters: Princess Bubblegum (Hynden Walch), the sovereign of the Candy Kingdom and a sentient piece of gum; the Ice King (Tom Kenny), a demented but largely misunderstood ice wizard; Marceline the Vampire Queen (Olivia Olson), a thousand-year-old vampire and rock music enthusiast; Lumpy Space Princess (Pendleton Ward), a melodramatic and immature princess made out of "irradiated stardust"; BMO (Niki Yang), a sentient video game console-shaped robot that lives with Finn and Jake; and Flame Princess (Jessica DiCicco), a flame elemental and ruler of the Fire Kingdom. The pilot first aired in 2007 on Nicktoons Network, where it was later re-aired on the incubator series Random! Cartoons. The pilot was eventually uploaded onto the internet and became a cult hit on YouTube. After Nickelodeon declined to turn the short into a full-fledged show, Cartoon Network purchased the rights, and Adventure Time launched as a series on April 5, 2010. The series concluded its ten-season run on September 3, 2018.
Each Adventure Time episode is about eleven minutes in length; pairs of episodes are often telecast in order to fill a half-hour program time slot. For the first five seasons, the show aired on Monday nights. However, starting with the early sixth-season episode "Breezy", the show began to shift both its timeslot and its day of airing. Upon its debut, Adventure Time was a ratings success for Cartoon Network, with its highest-rated episodes scoring over 3 million viewers. The show received positive reviews from critics and has developed a strong following among teenagers and adults, many of whom are attracted due to the series' animation, stories, and characters. Adventure Time has won three Annie Awards, eight Primetime Emmy Awards, two British Academy Children's Awards, a Motion Picture Sound Editors Award, a Pixel Award, a Peabody 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. Domestically, several compilation DVDs containing a random assortment of episodes have been released; additionally, all the seasons have been released on DVD and Blu-ray. A box set containing the entire series was also released on DVD on April 30, 2019. During its run, Adventure Time was produced by Cartoon Network Studios and Frederator Studios.
