Like many Gannett stations, KUSA dropped the "-TV" suffix ten days after the official digital television transition date of June 12, 2009, although KUSA had made the transition to digital-exclusive broadcasts nearly two months earlier.In April 1992, the station moved its operations into a new state-of-the-art facility at 500 Speer Boulevard (the original studio location was subsequently occupied by PBS member station KRMA-TV (channel 6)).It originally operated from studio facilities located in a converted former car dealership at 1089 Bannock Street in Denver's Civic Center neighborhood.Channel 9 gained an affiliation with the Du Mont Television Network in 1953, but lost CBS programming to KLZ-TV (channel 7, now KMGH-TV) when that station signed on in November 1953; this was followed by the loss of the NBC affiliation to KOA-TV (channel 4, now KCNC-TV) when it signed on in December of that year (both KLZ-TV and KOA-TV inherited the affiliations as a result of their sister radio stations' respective longtime affiliations with the CBS Radio Network and the NBC Red Network).In 1972, Mullins Broadcasting sold KBTV and sister station KARK-TV in Little Rock, Arkansas to the Combined Communications Corporation, owned jointly by Phoenix advertising mogul Karl Eller and Chicago advertiser John J.Louis, Sr., which already owned its flagship advertising business and stations KTAR-AM and KTAR-TV (the latter station is now KPNX-TV).The KBTV call letters are now at Beaumont, Texas' Fox-affiliated TV station.
Channel 9 served as the market's default NBC affiliate until May 14, 2000, when KNBN signed on as the Rapid City market's new NBC station.
This left KBTV as a primary Du Mont and secondary ABC affiliate.
The station struggled in the ratings for several years, in part because ABC's overall ratings were not on par with the other major networks until the 1970s.
Since 2006, Broncos games are aired on channel 9 when they are shown on NBC's Sunday Night Football.
In July 1996, Rapid City NBC affiliate KEVN-TV opted to join Fox, leaving the Black Hills region of South Dakota without a full-power NBC affiliate.
