I'm kind of numb to the sponsor thing. Its been around so long I look past it.
Lest we forget KI was, essentially one big Sponsorship... built to capitalize and propagate Taft and Hanna-Barbera Productions.
Attraction "Sponsors" are hardly unique to SF.... Heck KI opened several attractions with commercial names plastered all over them. Sherwin Williams, Bank America, Kahn's, Rainbo Bakers, Coke, Marathon Oil, Fotomat etc.
KI has had hundreds of them over the years. Remember Kodak Photospots? Or Kenton's Cove Keelboat Canal sponsored by Kayak Pools? How about Landscaping by John Deere? Shows at the American Heritage Music Hall sponsored by Chevrolet? One could go one and on.
Granted the ride cars didn't necessarily have the sponsor's names on them - but the signage and park paraphernalia sure did.
Finally, let's not discount the Paramount Years... where most every new attraction's theme was essentially a commercial for a dated movie title.
