Hey Mr. Crumudgeon, listen up.
The Rose Parade has ALWAYS been one big advertisement. Clubs, businesses, and other groups advertising. ALWAYS.
The TV showings have ALWAYS been a big ad for "beautiful CA weather in winter". People move to SoCal in droves after it's shown.
So, you ain't got a leg to stand on, bub.
As for Disney and "corporate greed"....jeez, how many times can one say that Walt Disney was a businessman who used synergy whenever he could to push all of his products?
