The Milwaukee Brewers are named after the city's history as a beer-making hub, and for the past 18 years, their stadium has been named Miller Park after the Miller Brewing Company. But their $40 million deal for the naming rights is up next year.

And beginning in 2021, the park will have a new sponsor: American Family Insurance. There's no word on what the actual new name will be, but there's a good chance it's just American Family Insurance Park.

Well, Milwaukee fans are NOT cool with this. They've started a petition on called Keep "Miller Park" as the official name for the home of the Milwaukee Brewers and it already has almost 50,000 signatures since it started on Tuesday.
