Yes, at Magic Mountain, each ride is sponsored by a new product each time I go.(and I go about once a month) Sometimes the products just switch rides. It's weird.
Shockwave at Drayton Manor in England is sponsered by 7-UP.
Big Dipper @ SFO has a 'This ride is brought to you by Coca-Cola' sign as you enter the ride platform.
