The call letters WMAM were previously assigned to a radio station in Beaumont, Texas, from August 1922 until October 1923.
WMAM in Marinette started in 1939, where the call letters reportedly stand for "Marinette and Menominee," or, "Wisconsin Michigan Air Messenger."
WMAM filed for a television license in July 1952, as WMBV-TV channel 11. By 1959, WMBV-TV moved to Green Bay and became WLUK-TV.
A notable personality at WMAM was Howard Emich, who worked at WMAM from 1940 to 1980. Known as "Marinette’s Newsman", he delivered over 10,000 news broadcasts and was inducted into the Wisconsin Broadcasters Association Hall of Fame in 1998.
