KBZK (channel 7) is a television station in Bozeman, Montana, United States, affiliated with CBS.

KBZK has its studios on Television Way in Bozeman; its primary transmitter is located atop High Flat, southwest of Four Corners.

The station was on the market from 1990 to 1993, when the Evening Post Publishing Company, through its Cordillera Communications division, acquired KCTZ from Big Horn.

When Robert L. Cooper, a Bozeman native, decided to pursue a television station for the city, he filed with the Federal Communications Commission (FCC) to have channel 7 moved from Butte to Bozeman for commercial use, rejecting the use of a channel on the ultra high frequency (UHF) band as unsuitable.

The FCC, however, found that a growing Bozeman merited a commercial VHF station and granted Cooper's request in November 1980.

[6] However, a comparative hearing among the four applicants, scheduled for August 1982, was forestalled when merger negotiations began among the group; by this time, Johnson had all but dropped out.

The Missoula-based Eagle Communications network—which also had a station in Butte—then obtained the ABC affiliation, which precluded it from being available to Bee's proposed Bozeman outlet.

[19] The Eagle acquisition never panned out; in January 1987, the FCC denied the proposed sale, claiming that KTVM-TV was already seen in Bozeman and that a new satellite station would be duplicative.

On its fourth day of operation, the station had to go off the air for five hours because its broadcasts interfered with medical telemetry equipment at Bozeman Deaconess Hospital that also used channel 7 spectrum.

He reached a deal with Big Horn Communications, owner of KOUS-TV, though he first had to offer Cooper the ability to buy KCTZ under the terms of his 1982 buyout.

[28] In 1993, the Evening Post Publishing Company, owner of KXLF-TV, acquired the station and received permission to operate it as a satellite of the Butte outlet.

[35] At that point, the station once again became a satellite of KXLF-TV (though with separate advertising)[36] and changed its call letters to KBZK-TV (the "-TV" suffix was dropped eight days later).

[31] Local news returned to KCTZ after the switch to Fox in 1996;[33] the station aired a 9 p.m. newscast, replacing its prior 6 and 10 p.m.

[41] In April 1999, the 9 p.m. news was moved back to 10 p.m., where its ratings tripled, and a 6 p.m. newscast was reintroduced, citing advertiser demand.
