Fun fact: even President Obama is a SpongeBob fan! From the Seattle Times:
""SpongeBob SquarePants" has been TV's most popular animated show for children aged 2 to 11 for seven years now, and a not-so-secret factor to its appeal is that many parents - and even people without kids - love it, too. It's a cash cow that has generated $8 billion in merchandising revenue for Nickelodeon.
"Hillenburg is an artist and also a scientist who taught, and the inspiration for many of his show's characters came from a comic he wrote, "The Intertidal Zone," designed to teach his students at the Ocean Institute about tidal pool characters.
"Through 125 episodes and guest shots by the likes of David Bowie, LeBron James, Whoopi Goldberg and Ray Liotta, the series has evolved and explored other characters to avoid repeating itself. But the essence of the show remains SpongeBob and his sweet innocence, Hillenburg said.
""I never really imagined a show about a sponge going past our first season," he said. "I thought maybe we'd have a cult following, and we'd be gone after one season. I'm in disbelief that we're here talking.""From: Seattle Times, July 13, 2009.
