Phineas and Ferb

Phineas and Ferb is an American animated musical-comedy television series created by Dan Povenmire and Jeff "Swampy" Marsh which aired on Disney Channel and Disney XD for four seasons between August 2007 and June 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.

Povenmire and Marsh conceived the characters while working together on animated programs The Simpsons and Rocko's Modern Life in the 1990s, and were inspired by the summers of their own childhoods. They developed the series together and pitched it to networks for 16 years before successfully selling the idea to The Walt Disney Company. Phineas and Ferb is produced by Disney Television Animation, and was originally broadcast as a one-episode preview on August 17, 2007, following the premiere of the made-for-television film High School Musical 2. It again previewed on September 28, 2007, and officially premiered on Disney Channel on February 1, 2008. The series originally concluded on June 12, 2015, before two new seasons were ordered in January 2023.

Phineas and Ferb is one of Disney Channel's most successful animated franchises. It received high viewership in the United States on cable television and influenced the development of merchandise, a live tour, spin-offs and movies. A made-for-television film, Phineas and Ferb the Movie: Across the 2nd Dimension, aired in 2011, while a follow-up titled Phineas and Ferb the Movie: Candace Against the Universe was released on Disney+ in 2020. Critics praised the writing and humor of the show, citing its appeal to a wide range of ages. However, some reviewers criticized its lack of originality and formulaic approach. The series won a Daytime Emmy Award in 2010 for Outstanding Writing in Animation, and won several Primetime Emmy Awards for Outstanding Individual Achievement in Animation.
