Channel 3 signed on the air on June 1, 1950 as WKZO-TV (the call letters standing for "Kalamazoo"). It was West Michigan's second television station to debut after WLAV-TV (channel 7, now WOOD-TV on channel 8) and was owned by broadcasting pioneer John Fetzer, along with WKZO radio, which Fetzer had owned since 1930. It carried programming from all four networks of the time; however, it has always been a primary CBS affiliate owing to its radio sister's longtime affiliation with the CBS Radio Network.
In 1985, Fetzer retired and began selling off his vast broadcasting empire, which by this time included, among other holdings, WWTV/WWUP-TV in Cadillac, Michigan and KOLN-TV in Lincoln, Nebraska. The FCC had grandfathered existing radio-television clusters when it barred common ownership of radio and television stations, but with Fetzer's announcement WKZO-AM-TV lost its grandfathered protection. The Fetzer television stations were initially sold to Gillett Holdings. However, due to FCC ownership limits in effect at the time, WKZO-TV and KOLN-TV were spun off to Busse Broadcasting. On December 5, 1985, per a since-repealed FCC rule restricting TV and radio stations in the same market but with different ownership from sharing the same callsigns, Busse changed the station's call letters to the current WWMT (standing for "We're West Michigan Television").
Its Souvenir Bold "3" was carried on for two years.
This logo is of similar design to the "3" emblem used at the time by eventual sister station KVBC in Las Vegas. In 1995, Granite Broadcasting acquired the station.
