MILWAUKEE --Miller park will soon lose it's namesake. 

A letter obtained by Spectrum News tells Miller employees naming rights will end with the company in 2020.

Miller Brewing Company secured the rights for 40-million dollars in 1996, before the stadium was even finished being built.

The new name hasn't been confirmed, but the letter also indicates that American Family Insurance will now hold those rights.

There will be a press conference for this major announcement this afternoon
