Season 1 of "All That" first aired on April 16, 1994 as a special preview, but later ran from December 24, 1994 to April 1, 1995.
After "You Can't Do That on Television" ended production in 1990, Nickelodeon had interest in creating another sketch comedy series for the network and debuted another sketch show called "Roundhouse" in 1992.
After the debut of "Roundhouse", Nickelodeon asked Mike Tollin and Brian Robbins to create a new show. The network wanted a show that was similar to "Saturday Night Live", but for kids.
Joe Davola, Kevin Kopelow, Dan Schneider and Heath Seifert were brought on as producers and were a major part of the writing force for the show. The producers went on a search to finds kids to join the cast after Nickelodeon green-lit the show. Angelique Bates, Lori Beth Denberg, Katrina Johnson, Kel Mitchell, Alisa Reyes, Josh Server and Kenan Thompson were hired.
In late 1992, Angelique Bates got a call from her agent about the show and she auditioned by doing an impression of Steve Urkel (which she would get to do various times on the show). Lori Beth Denberg was discovered by producers at a drama competition and was invited to audition & got the gig.
Katrina Johnson, Kel Mitchell, Alisa Reyes, Josh Server and Kenan Thompson went through a series of auditions to get on the show.
In 1994, Nickelodeon canceled "Roundhouse" and aired the pilot on April 16, 1994. The first season was broadcast from Orlando, Florida; it was taped from January to September 1994 at Nickelodeon Studios.
