All That season 9

During the off-season, Nickelodeon advertised and broadcast a competition called "R U All That?: Nickelodeon's Search for the Funniest Kid in America," a nationwide search to find the series a new cast member. The judges happened to be former cast members Amanda Bynes and Nick Cannon; Josh Peck was also a judge. After it ended in early 2003, said competition was broadcast on TV in a four-week special, with the finals airing on July 26, 2003. The contest picked five finalists, and all of them performed a sketch with some of the cast members. The winner was Christina Kirkman, who joined the show in the season opener and replaced Bryan Hearne. Ryan Coleman, the runner up in the contest, joined mid-season.

Ratings-wise, the show was not doing well. In order to raise ratings, the producers brought back old fan favorite sketches, like mous character Ed, as well as putting in Coleman in a test skit. They thought the fit would work, resulting in the revision of the skit.

This would be the final season for Shane Lyons, Giovonnie Samuels, and Jamie Lynn Spears. Shane Lyons revealed in episode 5 of Quiet on Set: The Dark Side of Kids TV that he was let go from the series after producers opted not to renew his contract. Giovonnie Samuels left because she felt was too old to be on All That, similar to original cast member Lori Beth Denberg exiting after Season 4. Jamie Lynn Spears left to star in her own Nickelodeon show Zoey 101, a show also created by Dan Schneider.

The cast of Season 9 continued to do On-Air Dares, akin to the last season. The intro was changed for this season, with the cast being set in the same place and are dancing in a dark room with the All That logo lit up in the back. The cast, however, is now wearing red, unlike the white that was used in Seasons 7 and 8. The "Oh" sign was brought back, and Brummet and Kirkman both held up the sign in the intro, similar to the previous two seasons. The intro was changed to accommodate Coleman's entry onto the show.

This is the first season since Season 3 to have more female cast members than male.

Following this season's conclusion, All That won Favorite TV Show at the 2004 Kids' Choice Awards for the first time in 4 years.
