Rich Stadium is now known as Ralph Wilson Stadium or “The Ralph.” It is the home field of the NFL’s Buffalo Bills football team. Its original name came from Rich Products of which the most famous one would be their non-dairy, whipped topping.
The stadium opened in 1973 and was, according to Wikipedia, one of the first examples of the sale of stadium-naming rights. After the 25-year deal expired in 1998, it was renamed after Buffalo Bills founder and owner, Ralph Wilson. It is located at 1 Bills Drive in Orchard Park.
