WMTP-TV signed-on with affiliations from the four major networks: ABC (primary), NBC, CBS, and DuMont. WMTP-TV lost NBC in 1954 to WMLA-TV (channel 2), and DuMont when it ceased most network operations in 1955.
After a swap of networks between WMTP and WGER (now WGXE), WMTP-TV became a primary CBS affiliate in 1957 when ABC was lost to WGER-TV (channel 7).
The typeface of the '9' in the logo would later be used by translator W14MT (channel 14) and after WMTP-TV changed networks and call letters.
WMTP-TV changed its call letters to WMMN-TV, signifying Mattupolis, Mattula, the station's market coverage and city of license, and the switch that moved NBC from WMLA-TV, which took the CBS affiliation thereafter.
In May 2019, WMMN-TV, along with sister station and MyNetworkTV affiliate WMMT (channel 50) and The Mattupolis Times, was acquired by GamerCraft as part of its merger with Craftsman Media.
