Phineas and Ferb is an American animated comedy-musical television series. Originally broadcast as a one-episode preview on August 17, 2007 and again previewed on September 28, 2007, the series officially premiered on February 1, 2008 on Disney Channel, and follows Phineas Flynn and his English stepbrother Ferb Fletcher on summer vacation. Every day, the boys embark on some grand new project, which annoys their controlling sister, Candace, who frequently tries to reveal their shenanigans to the boys' mother, Linda Flynn-Fletcher, and less frequently to their father, Lawrence Fletcher. The series follows a standard plot system; running gags occur every episode, and the B-Plot almost always features Perry the Platypus working as a spy ("Agent P") for OWCA (the Organization Without a Cool Acronym), to defeat the latest scheme of Dr. Heinz Doofenshmirtz, a mad scientist driven largely by a need to assert his evilness. Sometimes, other villains scoff at his level of evil. The two plots intersect at the end to erase all traces of the boys' project just before Candace can show it to their mother. This usually leaves Candace very frustrated. Creators Dan Povenmire and Jeff "Swampy" Marsh worked together on the Fox series The Simpsons and Nickelodeon series Rocko's Modern Life. The creators also voice two of the main B-plot characters: Major Monogram and Dr. Doofenshmirtz. Phineas and Ferb was conceived after Povenmire sketched a triangular boy—the prototype for Phineas—in a restaurant. Povenmire and Marsh developed the series concept together and pitched it 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 almost 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 earned the series a total of four Emmy nominations: in 2008 for the main title theme and for the song "I Ain't Got Rhythm" from the episode "Dude, We're Getting the Band Back Together", and then in 2010 for the song "Come Home Perry" from the episode "Oh, There You Are, Perry" as well as one for its score. The series has also been popular with adults.
On August 25, 2011, the show was picked up for a fourth season along with a possible spin-off show and a feature film on the Disney Channel. Disney Channel officially announced on November 9, 2011 that the fourth season was picked up with new episodes rolling out starting December 7, 2012. It is now the longest running Disney Channel Original Series, beating Kim Possible 's 5 years and 3 months, and is also the longest running Disney XD Original Series.
On February 15, 2014, it was announced that production of the show had been completed and no new episodes had been ordered, and that the show would go on an indefinite hiatus. However, new episodes started airing on Disney XD in June 2014, and on Disney Channel in the summer of 2014.
The show follows the adventures of stepbrothers Phineas Flynn (Vincent Martella) and Ferb Fletcher (Thomas Sangster), who live in the fictional town of Danville, in the Tri-State area. Their older sister, Candace Flynn (Ashley Tisdale), has two obsessions: "busting" Phineas and Ferb's schemes and ideas, and winning the attention of a boy named Jeremy (Mitchel Musso). Meanwhile, the boys' pet platypus, Perry, acts as a secret agent for an all-animal government organization called the O.W.C.A. ("Organization Without a Cool Acronym"), fighting Dr. Heinz Doofenshmirtz.
Sabrina Carpenter did additional voices in the episode "Ferb TV". She would later go on to star as Melissa Chase in Milo Murphy's Law, an animated television series from the creators of Phineas and Ferb.
