Phineas and Ferb is an American animated musical-comedy television series created by Dan Povenmire and Jeff "Swampy" Marsh that aired on Disney Channel and Disney XD for four seasons between 2007 and 2015. The series follows stepbrothers Phineas Flynn and Ferb Fletcher during summer vacation. Every day, the boys undertake the construction of a grand project, or embark on a spectacular adventure, to make the most of their time on vacation. This annoys their controlling older sister, Candace, who frequently tries to expose their schemes to her and Phineas's mother. The series follows a standard plot system; running gags occur in every episode.
A platypus was included in the series because of its interesting appearance.
Povenmire drew inspiration for the show from his boyhood in Mobile, Alabama.
Disney Channel was the first network to give the series a chance, though initially declined when Dan Povenmire originally pitched it to them.
