Mister Rogers' Neighborhood
Episode #1529 (1984)
MrBreakfast.com has a profile page on just about every breakfast cereal you can think of. On their page for Pac-Man Cereal, they have a screenshot of an episode of Mister Rogers' Neighborhood in which he takes a trip down the cereal aisle.
In this screenshot, Mr. Rogers is walking past boxes of Pac-Man Cereal and Donkey Kong Cereal, which has been stocked next to the Quentin Tarantino favorite, Kaboom. Ironically, Kaboom is also the name of an Atari 2600 game from 1981, but the cereal was themed after a circus clown.
