The series is based on a short produced for Frederator's Nicktoons Network animation incubator series Random! Cartoons. After the short became a viral hit, Cartoon Network picked it up for a full-length series that previewed on March 11, 2010 and officially premiered on April 5, 2010, and the series has been a critical and commercial success.
Following the animated short, Frederator Studios pitched an Adventure Time series to Nickelodeon, but the network passed on it twice.The studio then approached Cartoon Network, with creator Pendleton Ward delivering them an early storyboard for the episode, "The Enchiridion", showing that the premise could be expanded into a series while maintaining elements from the original short. Cartoon Network approved the first season in September 2008, and "The Enchiridion" became the first episode.The series was initially known as "Adventure Time with Finn and Jake", a title still used for some merchandise.
