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 The Simpsons beginning in 1988 (when the series was still being presented as shorts on The Tracey Ullman Show). The series became a smash hit for Fox, and its characters continued to represent the candy bar in commercial advertisements until 2001.

1st Tag (Nobody Better Lay a Finger on My Butterfinger) (1988-1998)

Visuals: On a black background with a blue floor, there is a 3D model of a Butterfinger with a bite taken out of it with the text "Nobody better lay a finger on my Butterfinger".

Variants:

Sometimes the model will change into a different model every time a different product is being advertised.
There is a prototype version of the logo where the text is absent and the background is black and blue circle gradient.
In the logo's final years, the Nestlé logo appears above.

Technique: CGI. The prototype is live-action.

Audio: Someone (mostly Bart from The Simpsons, voiced by Nancy Cartwright) saying the iconic line "Nobody better lay a finger on my Butterfinger!" or a variant of the line like adding "BBs" to the end (in the tag's final years, "From Nestlé" was added). The prototype variant has Bart say "It's Neat-O" followed by an announcer saying "And it's Neat-O!". In the tag's final year, a 6 note jingle was added.

Availability: Can be seen on some of their Simpsons commercials in the 80s and early 90s.

2nd Tag (Bite My Butterfinger) (1999-2001)

Visuals: On a yellow background, there is a Butterfinger (or Butterfinger BBs) with the text "Bite My Butterfinger" (later "Nothing like a Butterfinger! or no text).

Technique: CGI.

Audio: A jingle which instruments vary on ad based on the last tag's jingle. Someone (usually Bart again) says the text above the Butterfinger and is usually followed by Harry Shearer (or Scratchy on the first commercial to use the logo) saying "From Nestlé!"

Availability: Can be seen on some of their Simpsons commercials in the late 90s and early 2000s. Butterfinger stopped partnering with The Simpsons in 2001.
