Hillenburg initially began to work on creating the show shortly after the cancellation of Rocko's Modern Life in 1996. To voice the character of SpongeBob, Hillenburg approached Tom Kenny, who had worked with him on Rocko's Modern Life as a voice actor. SpongeBob was originally to be named SpongeBoy, but the name was already in use for a mop product. Upon finding it out, Hillenburg decided to use the name "SpongeBob." He chose "SquarePants" as a family name, as it referred to the character's square shape and it had a "nice ring to it."
