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.
