<P> In addition, it was also the first Disney Channel sitcom to be shot on videotape, to use a multi-camera format, to be shot in front of a studio audience or use a laugh track, and to use the simulated film look created by FilmLook, Inc. (all of which has become standard on all Disney Channel comedies, though a' filmized' appearance was given to all of the channel's videotaped sitcoms produced from 2009 onward, as the live - action Disney Channel Original Series begin being produced in high definition). </P> <P> The first three seasons were produced by Brookwell McNamara Entertainment . The company later left at the end of season 3, being replaced by Warren & Rinsler Productions . Raven - Symoné then received a producer credit for the show's fourth and final season, with the credit being called "That So Productions". It became the first Disney Channel series to create a spin - off, Cory in the House, which followed her younger brother, Cory, as his dad became the head chef for the President of the United States, causing the two of them to move to Washington, D.C. </P> <P> In the fourth season of That's So Raven and on Cory in the House, Victor states that Tanya (T'Keyah Crystal Keymáh) is in England studying to be a lawyer . The show shot its final few episodes in January 2006, but they weren't all aired until a year later, with the series finale airing in March 2007 and the second - to - last episode shown that November . </P> <P> The show's title theme song was written by John Coda, who also composed the music cues to signify scene changes and commercial breaks for this series as well as Even Stevens . It was produced by Jeffrey "Def Jef" Fortson and Christopher B. Pearman and was performed by Raven - Symoné, Anneliese van der Pol and Orlando Brown . </P>
