According to former Mars executive Alfred Poe, PB Max was discontinued due to the Mars family's distaste for peanut butter despite $50 million in sales.
Early television commercials for PB Max declared that the "PB" in its name didn't stand for things such as piggy banks, polka band, portly ballerina, platinum blonde, penguin black belt, pig basketball, plow boy, pure bliss, parachuting buffalo, or pink baboon — but that it, in fact, stood for peanut butter.
