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).
WGRZ
WGRZ-TV nearly lost its NBC affiliation in 1994 when NBC's parent company, General Electric, announced plans to purchase King World Productions, the then-owner of CBS affiliate WIVB-TV (channel 4). Had it occurred, WIVB-TV would have become an NBC owned-and-operated station. However, the deal never materialized, and WIVB-TV was sold to the LIN TV Corporation instead (coincidentally, King World would eventually be acquired by CBS parent CBS Corporation, who merged the company into CBS Television Distribution in 2007). However, it "did" lose the local rights to the Buffalo Bills to WIVB-TV when the NFL returned to CBS in 1998 after the network acquired the rights to the American Football Conference package (this ended a 33-year run for channel 2 as the Bills' unofficial home station). Presently, the station airs Bills games when they are featured on NBC's "Sunday Night Football".
