With over 500 episodes of The Simpsons aired on TV, and tons of Apple links, even a hardcore Simpsons and Apple fan might have missed this tribute to Apple. In episode #497 “The D’oh-cial Network” Lisa builds a social-network called SpringFace. The computer behind Lisa’s coding prowess was a Lisa computer by Mapple at the Springfield High School computer lab.
The Apple nod is a reference to the Apple Lisa which was released in 1983, and is named after Steve Jobs’ first daughter, Lisa Brennan-Jobs. The logo on the Simpsons’ Lisa computer is the Mapple logo which is just an apple that has been bitten on both sides.
