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 (voiced by 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 (voiced by Hynden Walch), the sovereign of the Candy Kingdom; the Ice King (voiced by Tom Kenny), a demented but largely misunderstood ice wizard; Marceline the Vampire Queen (voiced by Olivia Olson), a thousand-year-old vampire and rock music enthusiast; and BMO (voiced by Niki Yang), a sentient video game console-shaped robot that lives with Finn and Jake. The pilot first aired in 2007, and it was later re-aired on the incubator series Random! Cartoons on Nicktoons Network. The pilot eventually leaked 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. Season seven, which also contains a special mini-series, began airing on November 2, 2015. The show has also been renewed for an eighth and ninth season, and a feature-length film—which is being developed by Chris McKay and Roy Lee—is also in the works.
