==History==
On March 20, 1982, a group of media entrepreneurs and engineers known as the "Tombstone Media Company" set up a TV station willing to serve southeastern Arizona under the call letters "KMBS" and was planned to become an independent station. Later that year in April, KMBS was one of the first local stations in North America (and the first in the state of Arizona) to report the well-known Argentine invasion of the British overseas territory of the Falkland Islands (known locally as the Islas Malvinas) in the South Atlantic.
In 1983, the station changed its call letters to KMBN to avoid confusion with CBS affiliate KMBS Channel 7 in Monterey, California, which used them two months before they became allowed to used the KMBS callsign.
From May 12 to December 20, 1986, channel 21 became an official NBC affiliate after its programming was cherry-picked by rivals Sierra Vista-based ABC affiliate KSVS (channel 2) and Bisbee-based CBS affiliate KBSB (channel 7). That day at 8:59pm, current owner Nexstar Broadcasting Group bought the station from Tombstone Media and made it a Fox affiliate overnight. KSVS was an NBC affiliate until May 14, when it dropped most of its NBC programming to become an ABC affiliate.
As a Fox affiliate, it mostly pre-empted great Fox TV shows like The Tracy Ullman Show, Baywatch and 21 Jumpstreet, with episodes replayed from charter affiliate KBSN (channel 12). and in September 1988, due to financial problems from local rival KBSN, the swap was reversed and channel 21 become an NBC affiliate once again. This time under the new callsign "KNBT", standing for NBC Tombstone.
It was sold to Key Communications on December 29, 2016.
On January 16, 2017, KNBT cased to use the "Local 21" branding and has been referred to as just "KNBT", but then took back the branding the next year.
In May 2018, Bayou City Broadcasting announced they would be purchasing Key Communications' stations, including KNBT for $178 million.
