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 series is based on a 2007 short film that aired on Nicktoons. 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 ( Olivia Olson), BMO ( Niki Yang), and others. The series follows the adventures of a boy named Finn ( Jeremy Shada) and his best friend and adoptive brother Jake ( John DiMaggio)-a dog with the power to change size and shape at will. Adventure Time is an American fantasy animated television series created by Pendleton Ward and produced by Frederator Studios for Cartoon Network.
