I have never seen so much corporate sponsorship in any Disney park.
You might want to do some research on Disney theme park history then. DCA, as it stands in 2006, has much less corporate sponsorship than Disney parks did 20 or 40 years ago.
Look at Tomorrowland circa 2006, where barely anything has a sponsor anymore;
Innoventions - An odd mish-mash of HP, Pioneer, Honda and St. Josephs Hospital
HISTA - Kodak
Autopia - Chevron
Now go back to Tomorrowland 1967, after Walt had made Disneyland a roaring success but still sought out a sponsor for every show, restaurant and attraction because he was such a big believer in the wonderful American Free Enterprise system;
Autopia - Richfield Oil
Submarine Voyage - General Dynamics
Disneyland Monorail - Santa Fe Railroad
Carousel of Progress - General Electric
Tomorrowland Terrace - Coca-Cola
Flight To The Moon - McDonnel Douglas
PeopleMover - Goodyear Tire & Rubber
Adventure Thru Inner Space - Monsanto
CircleVision - Bell System
And that was just in one land. There were sponsors everywhere under Walt's watch. Heck, they even had
Pepsi-Cola and
Coca-Cola at the same time at Disneyland in the 50's, 60's and 70's. The Golden Horseshoe had a big
Pepsi-Cola logo hanging from the stage, but Refreshment Corner down on Main Street served
Coca-Cola. It just depended which restaurant you were at which soft drink they served. Then there was the Casa de Fritos, serving...
Fritos with every meal! Or the
Aunt Jemima Pancake House. Or the
Sunkist I Presume juice stand in Adventureland. But if you were in Fantasyland you got a drink at the
Welches Grape Juice Bar near the Snow White ride. Over at the Tiki Room in the 1960's you were greeted by a big sign reminding you that
United Airlines was the
Extra Care Airline with direct jet service to Hawaii.
I could go on and on and on, bringing up all the corporate sponsors that were just in Disneyland during Walt's day, but I think you get the point.
Sponsorship has always been a part of Disney theme parks, and Walt was very proud to showcase American industry in his park. There still is sponsorship today, but it's at a dramatically reduced level than what it was just 20 years ago. As Disney theme parks have become a bit less special and less unique, many corporate sponsors have left Disney and gone their own way in presenting their product to American consumers.
I wish we had more sponsors back in Disney theme parks, especially DCA. There are so many wonderful California companies that are noticeably absent from DCA. See's Candy, Ghiradelli Chocolate, Apple Computer, Boeing, practically any major automaker with big design studios in Southern California, the lumber industry, any number of surfboard or skateboard equipment and clothing companies, etc., etc.
