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).
WISN-TV
In 1961, CBS decided to affiliate with WISN-TV, as its sister radio station had been a longtime affiliate of the CBS Radio Network. As a result, Storer Broadcasting-owned WITI-TV (channel 6) and WISN swapped networks: channel 12 switched its affiliation to CBS and channel 6 became an ABC affiliate on April 2, 1961. During channel 12's time with CBS, it served as the default home station for the NFL's Green Bay Packers for the Milwaukee market, and airing the team's first two Super Bowl appearances (also the first two Super Bowl games in NFL history); it was succeeded and preceded in this stead by WITI.
