Bart, and other "The Simpsons" characters, have appeared in numerous television commercials for Nestlé's Butterfinger candy bars from 1990 to 2001, with the slogan "Nobody better lay a finger on my Butterfinger!" Lisa would occasionally advertise it too. Matt Groening would later say that the Butterfinger advertising campaign was a large part of the reason why Fox decided to pick up the half-hour show. The campaign was discontinued in 2001, much to the disappointment of Cartwright. Bart has also appeared in commercials for Burger King and Ramada Inn. In 2001, Kellogg's launched a brand of cereal called "Bart Simpson Peanut Butter Chocolate Crunch", which was available for a limited time. Before the half-hour series went on the air, Matt Groening pitched Bart as a spokesperson for Jell-O. He wanted Bart to sing "J-E-L-L-O", then burp the letter O. His belief was that kids would try to do it the next day, but he was rejected.
