WNAM-TV signed on from Neenah, Wis., in 1955. It was the sister station of WNAM-AM, which signed on eight years earlier.
WNAM-TV broadcast over UHF Channel 42. It soon moved to VHF Channel 5 and changed its city of license to Green Bay. The station also changed its call letters to WFRV-TV. The ABC affiliate switched to NBC in 1959.
In 1958, WFRV became the first station in the area to broadcast in color. It also was the first to cover a live lunar eclipse in 1959. WFRV also had the city’s first color local news broadcasts in 1965.
WFRV switched back to ABC in 1983. Midwest Radio and Television, owner of WCCO in Minneapolis, purchased WFRV in the late 1980s. CBS purchased Midwest in 1991, taking ownership of WFRV-TV. CBS already had been affiliated with Green Bay’s WBAY-TV for decades and was unwilling to drop the station.
CBS tried to sell WFRV and Escabana, Mich., satellite station WJMN-TV, but no one bought it. CBS moved its programming to WFRV in 1992. WBAY picked up the ABC affiliation.
In 2011, the station became the first in Green Bay to broadcast local newscasts in high definition.
For most of its history, WFRV-TV’s news ratings have run behind WBAY-TV and second-place WLUK-TV.
Nexstar Broadcasting owns the station today.
