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).
WLUK-TV
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. WLUK began to provide technical, engineering, promotional, administrative and other operational support services for WIWB, with advertising sales services under a related but separate joint sales agreement. That station moved its operations into WLUK's studios that August. LIN would purchase WCWF outright in April 2011, under a failing station waiver (an indication that the station was in an economically non-viable position, which permitted a duopoly even though Green Bay has only seven full-power stations, one fewer than that required by FCC rules to legally permit a duopoly between WLUK and WCWF if both were economically viable), creating the Green Bay market's first legal television station duopoly.
