(except for Dr Pepper, which shouldn't be owned by them)

Pepsi doesn't own Dr Pepper, they're just bottling/canning and distributing it in your area. Here in Houston, TX it says on the can in front of me "Canned by Dr Pepper Bottling Company of Houston Inc., Houston, Texas 77054 under the authority of Dr Pepper Company, Plano Texas 75024."

When I was in Seattle, the Dr Pepper was bottled by Coca-Cola. It all depends on which part of the world.
