On April 28, 1956, Channel 6 signed in as WDMJ-TV, the Upper Peninsula's first television station. The station carried programming from all three networks offered at that time, but was a primary CBS affiliate. WDMJ was owned by the "Daily Mining Journal" along with WDMJ radio (1320 AM). Its studios were on the top floor of the "Mining Journal" building on Washington Street in Downtown Marquette. The station quickly outgrew its facilities. In 1959, the station moved into its current studios in Negaunee Township. In 1964, it was sold to Post Corporation, owners of WLUK-TV in Green Bay, Wisconsin, who changed the calls to WLUC-TV to match its moniker at the time "Lucky 6". WLUC first aired network programs in color in 1963, and with the purchase of color video tape equipment, it began broadcasting all locally produced programs in color in 1969. The station moved its transmitter to southeast of Republic in 1980 and dismantled the original one near its current studios in Negaunee.
