To call Fred Seibert "a producer" is like calling Steve Hillenburg "a guy who drew a sponge." A visionary force in the early days of Nickelodeon, the former president of Hanna-Barbera, and the current big cheese behind Frederator, Fred has produced cartoon classics such as The FairlyOddparents, Adventure Time, Fanboy and Chum Chum, and Bee And Puppy Cat, to name a few. To us, he's a legendary animation entrepreneur, even though Fred calls himself a professional fan.
