NFL on CBS
A number of NFL teams and their broadcasting departments have teamed up with CBS Sports to produce games; , these teams include the New York Jets (WCBS-TV in New York City) and Green Bay Packers (WGBA-TV in Green Bay and co-flagship WTMJ-TV in Milwaukee; since former CBS O&O WFRV-TV in Green Bay lost the local rights to the preseason games, Packers coverage on WGBA and WTMJ currently uses NBC's graphics package as both are affiliates of that network, although the telecasts continue to use a CBS technical and announcing team).
WCWF
On June 4, 2010, LIN TV Corporation, owner of Green Bay's Fox affiliate WLUK-TV, as part of an agreement with ACME Communications in three markets where both companies owned stations, announced that it would begin to operate WIWB through separate shared services and joint sales agreements; WLUK would provide WIWB with technical, engineering, promotional, administrative and other operational support services, as well as joint advertising sales for the two stations. As part of its agreements with ACME, LIN TV had the option to purchase WIWB, an option it exercised in September 2010, purchasing not only WIWB but another CW station in a similar arrangement, Dayton, Ohio's WBDT. LIN TV included in its license transfer request to the Federal Communications Commission a "failing station waiver," an indication that the station was in an economically non-viable position and that FCC should relax ownership limits that apply to the Green Bay market so that Channel 14 could stay on the air; that limit (found in CFR§73.3555(b)(2) of the FCC's rules) permits ownership duopolies in markets with at least eight full-power stations, whereas Green Bay has only seven (Journal Communications would also seek a waiver in its 2012 purchase of WACY-TV, which has been operated through Journal-owned WGBA-TV since 1994). 
In April 2011, the FCC approved the ownership transfer of WCWF from ACME to LIN TV, also applying the requested failing station waiver. Additionally, the FCC denied a petition from Time Warner Cable, the dominant cable provider in Northeast Wisconsin; the FCC dismissed as speculative TWC's claims that higher retransmission fees for WCWF, when paired with those for WLUK, would result from LIN TV's purchase of the station, and that LIN's collective retransmission plans for both stations did not violate FCC rules. The sale of WCWF to LIN was consummated on May 20, 2011.
