Butterfinger

Background
Butterfinger is a candy bar manufactured by Ferrero SpA, a subsidiary of Ferrero. It consists of a layered crisp peanut butter core covered in a chocolatey coating. Invented by Otto Schnering of the Curtiss Candy Company in 1923, the name of the candy was chosen by a popularity contest. In its early years, it was promoted by Shirley Temple in the 1934 film Baby Take a Bow. Butterfinger was advertised by characters from an animated sketch series on Fox's The Tracey Ullman Show called The Simpsons beginning in 1988. The animated series became a smash hit for Fox, and its characters continued to represent the candy bar in commercial advertisements until 2001.
