Saved by the Bell Engel was skeptical of the new format at first, and did not want to make children's programming. However, his wife convinced him that making the show would be a worthwhile endeavor, and he soon told Tartikoff he would do the show.[14] Engel felt, however, that Indianapolis was not exciting as a location, and moved the show to a semi-fictional part of Los Angeles, "the Palisades." The main locations of the show would be the teenager's school, Bayside High, and The Max, a fictional eatery they frequent. In addition, they would film before a live studio audience.[7][16]
