WLUC has been affected several times by television shakeups in Green Bay, since rival station WJMN-TV (channel 3) in Escanaba is a semi-satellite of Green Bay-based WFRV-TV. For example, it dropped NBC programming in 1969 when WJMN signed on. In 1983, when WJMN-TV (along with parent station WFRV-TV) switched from NBC to ABC, WLUC took a secondary NBC affiliation. When CBS bought WFRV in 1992 and switched it from ABC, WLUC became a primary ABC station with secondary NBC affiliation. It became solely NBC in 1995 when WLUK and WGBA-TV exchanged affiliations. As a result, it is one of the few stations in the country to have been with all of the big three networks. WLUC also carried some Fox programs in the early 1990s before WLUK switched to the network.
