>so and so at the AT&T stadium

In at least one town with a stadium of that name, most people do not refer to it by that name. Instead, it is referred to as Jerry's World for the owner of the franchise.

Concert venues are another naming rights area that is confusing. There's one in particular that has had its name changed so many times that I do not know what it is currently called. Instead, it is often referred to by the original sponsor by pretty much anyone of a certain age. Even if you call it the older name to younger people, they know which venue. Some names stick.
