SpongeBob SquarePants is a Nickelodeon animated franchise created by marine biologist and animator Stephen Hillenburg, premiering May 1, 1999, and now in its seventeenth season. The longest-running animated series in Nickelodeon’s history and the longest-running American animated primetime series, SpongeBob follows an optimistic sea sponge, his best friend Patrick Star, and a cast of undersea neighbors through comedic adventures in the underwater city of Bikini Bottom. Six theatrical and streaming films, multiple spinoff series, a Broadway musical, and a merchandise operation generating billions of dollars have extended the franchise across every consumer category since its debut.
Stephen Hillenburg developed SpongeBob SquarePants from an earlier project called The Intertidal Zone, which he had created as an educational comic while working as a marine science educator. After joining the Nickelodeon production of Rocko’s Modern Life, where he met voice actor Tom Kenny, Hillenburg developed the full SpongeBob concept for a Nickelodeon pitch. The series premiered with three shorts on May 1, 1999, and quickly became the cornerstone of Nickelodeon’s programming schedule, driving merchandise sales, network promotion, and cultural visibility that no other Nickelodeon property has matched.
Tom Kenny voices SpongeBob, Bill Fagerbakke plays Patrick Star, Rodger Bumpass plays Squidward Tentacles, Clancy Brown plays Mr. Krabs, Carolyn Lawrence plays Sandy Cheeks, Mr. Lawrence voices Plankton, Jill Talley voices Karen, Mary Jo Catlett plays Mrs. Puff, and Lori Alan plays Pearl. The core cast has remained consistent across the full run of the show. The series surpassed the twenty-season mark while retaining its status as Nickelodeon’s flagship property, something Hillenburg had not originally intended, having planned for the show to end with the first theatrical film in 2004.
Stephen Hillenburg died November 26, 2018, from ALS. The show has continued under showrunners Marc Ceccarelli and Vincent Waller. Season 16 premiered June 27, 2025, and Season 17 premieres June 12, 2026.
The SpongeBob SquarePants Movie released November 19, 2004, as the theatrical conclusion Hillenburg originally intended for the series, following SpongeBob and Patrick traveling to Shell City to recover King Neptune’s crown. The film grossed $140 million worldwide. The SpongeBob Movie: Sponge Out of Water in February 2015 used a combination of traditional animation and live-action sequences as SpongeBob and Plankton team up to recover the Krabby Patty formula. The SpongeBob Movie: Sponge on the Run arrived in Canada in 2020 and on Paramount+ in the United States on March 4, 2021, introducing the prequel spinoff series Kamp Koral.
Saving Bikini Bottom: The Sandy Cheeks Movie, released August 2, 2024, on Netflix as a spinoff film celebrating the franchise’s twenty-fifth anniversary, followed Sandy Cheeks returning to Texas. Plankton: The Movie, released March 7, 2025, on Netflix, followed Plankton and debuted as the number one kids title globally on the platform. The SpongeBob Movie: Search for SquarePants, the fourth theatrical SpongeBob film, released December 19, 2025, in the United States, with Paramount+ streaming rights to follow in Summer 2026.
Kamp Koral: SpongeBob’s Under Years launched on Paramount+ in March 2021, following a young SpongeBob and Patrick at summer camp before the events of the main series. The show ran two seasons before concluding in 2024. The Patrick Star Show premiered on Nickelodeon in July 2021, following Patrick Star’s family in a talk show format, and continues in its fourth and fifth seasons. Both spinoffs were produced over Hillenburg’s original wishes against extending the SpongeBob universe beyond the main series, a stance the franchise’s subsequent producers have not maintained.
SpongeBob SquarePants: Battle for Bikini Bottom in 2003, developed by Heavy Iron Studios and published by THQ, is the franchise’s most beloved game, a 3D platformer that captured the show’s visual style and humor well enough to maintain an active fan community two decades later. A remake, Battle for Bikini Bottom: Rehydrated, was developed by Purple Lamp Studios and published by THQ Nordic in 2020. The SpongeBob Game, The Cosmic Shake, and multiple licensed games have extended the franchise in gaming across generations of hardware. THQ Nordic’s SpongeBob SquarePants: Titans of the Tide released in November 2025. SpongeBob Tower of Defense on Roblox has surpassed 500 million visits, representing the franchise’s significant presence in the user-generated gaming space.
SpongeBob SquarePants: The Broadway Musical opened at the St. James Theatre in New York City in December 2017 following out-of-town tryouts in Chicago. The production featured an original score contributed by a diverse roster of musicians including David Bowie, Cyndi Lauper, John Legend, Lady Antebellum, and They Might Be Giants rather than a single composer. The show received twelve Tony Award nominations and won the award for Best Scenic Design, becoming one of the more commercially successful licensed Broadway productions of its era before closing in September 2019 after 327 performances.
