Phineas and Ferb (also known as Disney's Phineas and Ferb) is an American animated television series. Originally broadcast as a preview on August 17, 2007, on Disney Channel, the series follows two suburban stepbrothers on summer vacation. Each day the pair devise ambitious, involved plans and inventions to stave off boredom, often bringing them into conflict with their snoopy sister, Candace. The series follows a standard plot system; running gags occur every episode, and the B-Plot almost always features the boys' pet platypus acting as a secret agent to fight an evil scientist named Heinz Doofenshmirtz. The two plots intersect at the end to erase all traces of the boys' project just before Candace can show it to their mother.
Creators Dan Povenmire and Jeff "Swampy" Marsh worked together on the Nickelodeon series Rocko's Modern Life. Phineas and Ferb was conceived after Povenmire sketched a triangular boy — the blueprint for the titular Phineas — in a restaurant. Povenmire and Marsh developed the series concept together and pitched to networks for 16 years before securing a run on Disney Channel. The series is also known for its musical numbers, which have appeared in every episode since the first-season "Flop Starz". Disney's managers particularly enjoyed the episode's song, "Gitchee, Gitchee Goo", and requested that a song appear in each subsequent episode. The show's creators write and record each number, and vary musical tempo depending on each song's dramatic use. The music has gotten the series two Emmy nods for songwriting in 2008.
