I was inspired by linguist Heidi Harley's catalog of Simpsons linguistic phenomena to start a parallel list of fictitious brand names used on episodes of The Simpsons.
It's a tough job--much tougher than I'd imagined--and, frankly, nobody has to do it. Nevertheless, I did it. Or at least took a preliminary stab. The job was made somewhat easier by the gnomes of Wikipedia, the Simpson Crazy fan site, and this directory interactive map of Springfield. (UPDATED with new URL and cooler map.)
There's a backlog of episodes whose scripts still haven't been uploaded to fan sites, and I didn't begin taking notes until this year, so the list is weighted toward the 1990s. Dates, when provided, refer to an episode's first airing. And yes, this is a work in progress, so feel free to add a comment with your own favorites.
UPDATE: Simpsons Brand-o-Rama Part Deux (posted June 2008) is here. And Part Trois (posted June 2009) is here.
