Title: Yo Gabba Gabba!
Content:  Yo Gabba Gabba! was developed by two Southern California fathers and punk rockers, Christian Jacobs and Scott Schultz, who first started working together as teenagers, producing and directing skateboarding videos. Their goal was to design a kids' show that was entertaining while featuring real artists and real performers. Both had no past experience writing scripts for television, let alone children's broadcasting or education. In developing the show they took inspiration from a number of classic children's series including Sesame Street, The Electric Company, Pee-wee's Playhouse, ZOOM, as well as Sid and Marty Krofft puppet shows Banana Splits and H. R. Pufnstuf. In 1999, after becoming parents, Jacobs and Schultz started playing around with ideas for children's television and produced a pilot independently financed by small loans from friends and family. Yo Gabba Gabba! did not get much attention until it started circulating on the Internet. Jared Hess, the director of Napoleon Dynamite and Nacho Libre, saw the pilot online and recommended it to Brown Johnson, the executive vice president and executive creative director of Nickelodeon Preschool.
