SpongeBob SquarePants (often referred to simply as SpongeBob) is an American animated television series, created by marine biologist and animator Stephen Hillenburg. Much of the series centers on the exploits and adventures of the title character and his various friends in the underwater city of Bikini Bottom. The series' popularity has prompted the release of a media franchise, contributing to its position as Nickelodeon's highest rated show, the most distributed property of MTV Networks, and among Nicktoons' most watched shows. It is listed 15th in IGN's top 100 animated series list.
When Rocko's Modern Life ended in 1996, Hillenburg began working on SpongeBob SquarePants. He teamed up with several Nickelodeon veterans and Rocko crew members, including creative director Derek Drymon (Action League Now!, Hey Arnold!, and Rocko's Modern Life) writers and directors Sherm Cohen, and Dan Povenmire, writer Tim Hill, actor and writer Martin Olson, animation director Alan Smart (all from Rocko's Modern Life), and story editor Merriwether Williams (The Angry Beavers), who worked on the series for its first few seasons and switched to SpongeBob SquarePants in July 1999.
