WLUK became a Fox affiliate on August 28, 1995, swapping affiliations with WGBA-TV (channel 26), which had acquired the Fox affiliation three years earlier after WXGZ-TV (channel 32, now WACY-TV) shut down due to financial issues.Like most former "Big Three" network affiliates that switched to Fox during that time, WLUK picked up almost no syndicated programming from WGBA, though it was unnecessary because of WGBA's local marketing agreement with WACY-TV (channel 32); WGBA's programming largely moved to that station instead.Since channel 11 joined Fox, Packer football games have routinely drawn an 80% share of the viewing audience – far and away the highest-rated programs in the market, and through Fox's NFL rights deal, the station has broadcast two of the three Super Bowl games the Packers have appeared in, both victories, since 1994; Super Bowls XXXI and XLV, both by far the highest-rated programs in the Green Bay market's history.
On August 22, LIN TV Corporation purchased WLUK in a $260 million deal that included WALA-TV and sister station WBPG in Mobile; WTHI-TV in Terre Haute, Indiana and KRQE-TV in Albuquerque, New Mexico; the sale closed on December 1, 2005.
On June 4, 2010, LIN TV entered into shared services and local sales agreements to operate CW affiliate WIWB (channel 14, now WCWF) as part of a deal involving LIN and ACME Communications-owned stations in markets where both companies owned stations.
It aired some local entertainment programs, including a Saturday night polka show and a daily children's cartoon show using the franchised Bozo the Clown character.
In 1983, WLUK reclaimed the market's NBC affiliation, when WFRV switched to ABC. Gillett's Gillett Broadcasting purchased Post Corporation. Gillett in turn sold the station to Burnham Broadcasting later that year, in order to purchase the KKR stations (which included future fellow Fox station WITI in Milwaukee).
For most of its second stint with NBC, WLUK largely downplayed its affiliation, even during the network's powerhouse days of the 1980s; it used the NBC Peacock only sparingly in the station's advertisements.
