Continuing with the Toy Story theme, when you get done with the ride, you're emptied into a gift shop selling Toy Story-related paraphernalia. Many of the products sold here are Disney-branded items, like the stuffed Buzz Lightyear (with matching blanket!) that we bought for our son. There are also numerous items that are not, like the Barbie dolls (Mattel) and the LEGO Toy Story sets. I don't claim to know the details of the contracts between these companies and the Disney empire, but I'm sure it's a sweet one!
It's also a probably a confusing mess to figure out, even if someone DID get their hands on the contract. The backs of all these products say, "Used by permission," by there's obviously money involved. I think the toy maker has to pay to use names and images, but then I think Disney has to pay something, too. Again, I'm not sure.
No matter what the contract is for, if you can get in with Disney, you could be set for life.
