where did the idea of spongebob come from
SpongeBob SquarePants Many of the ideas for the series originated in an unpublished educational comic book titled The Intertidal Zone, which Hillenburg created in 1989.[3] He began developing SpongeBob SquarePants into a television series in 1996 upon the cancellation of Rocko's Modern Life, and turned to Tom Kenny, who had worked with him on that series, to voice the title character. SpongeBob was originally going to be named SpongeBoy, and the series was to be called SpongeBoy Ahoy!, but both of these were changed, as the name was already trademarked.
