Pre-launch (1952) Following the
Federal Communications Commission (FCC)'s "freeze" on new television station licenses in 1948, Colorado politicians, including Senators
Edwin C. Johnson and
Eugene Millikin, formally protested the commission's proposed allocations for the state. They argued that limiting Denver to three
VHF channels would stifle competition and requested additional allocations. When the FCC lifted the freeze in April 1952, the Colorado Television Corporation—owner of radio station
KVOD (now KHOW)—applied for the channel 9 license on June 19, 1952. The corporation was capitalized at $1 million and led by W. D. Pyle and T. C. Ekrem; major stockholders included
Aksel Nielsen (president of the Denver Chamber of Commerce), oilman Maurice Robineau, and former Colorado Attorney General
Gail Ireland. Initially, the application for channel 9 was contested by the Empire Coil Company of
New Rochelle, New York. However, Empire Coil amended its application to seek
UHF channel 26 instead, wishing to avoid a lengthy competitive hearing. Consequently, on July 11, 1952, the FCC granted construction permits to the Colorado Television Corporation (channel 9),
KFEL-TV (channel 2), and Empire Coil (channel 26). These were among the first television grants issued by the government in nearly four years. Following the grant, station officials initially projected a 90-day timeline to get on the air. In August 1952, the company hired Joe Herold, a former technical director for
WOW in
Omaha, Nebraska, and consultant for stations in
Brazil and
Cuba, as the station manager. Jerry Lee was appointed commercial manager, while Ekrem traveled to New York to negotiate a network affiliation. Although the station was informally referred to as KVOD-TV in the press throughout the summer, the FCC officially assigned the call letters KBTV on September 11, 1952. Construction of the station's transmitter building and the erection of a six-bay antenna took place on
Lookout Mountain in September 1952, located directly south of the transmitter for KFEL-TV, which had launched in July. While the station set a firm launch date of September 29, delays in the delivery of a 2,000-watt amplifier from the
Radio Corporation of America forced a postponement. Further technical difficulties with the transmitter stalled attempts to air a test pattern on September 30 and October 1.
Launch and first years (1952–1954) KBTV began broadcasting test patterns on October 2, 1952, operating under a special temporary authority from the FCC. The station officially commenced regular commercial programming at 2:15 p.m. on October 12, 1952. It was the second television station to sign on in the Denver market, launching just over three months after KFEL-TV (channel 2, now
KWGN-TV), which had signed on July 18. The first program aired on the station was
Quiz Kids at 2:30 p.m. Upon its debut, KBTV served as a primary affiliate for both the Columbia Broadcasting System (
CBS) and the
American Broadcasting Company (ABC), carrying a slate of programming that included
Super Circus and ''
What's My Line?''. Weeks after its launch, KBTV participated in the first coast-to-coast television coverage of a presidential election on November 4, 1952. The station utilized feeds from both CBS and ABC to broadcast returns for the race between
Dwight D. Eisenhower and
Adlai Stevenson II. The station's high-altitude transmitter site on Lookout Mountain proved vulnerable to severe weather and technical faults during its early years. Viewers reported outages during the election cycle due to transmitter difficulties, and severe electrical storms and high winds caused power failures and equipment misalignment in August and December 1953. Originally operating from studios at 1100 California Street, the station purchased a building—a former automobile agency and car dealership—at 1089 Bannock Street in November 1952. Operations moved to the new facility in May 1953. In July 1953, KBTV increased its effective radiated power to 240,000 watts, the maximum permitted for the channel at the time. The Denver television market underwent a significant realignment in late 1953 with the launch of
KLZ-TV (Channel 7) and
KOA-TV (Channel 4). Channel 9 gained an affiliation with the
DuMont Television Network in 1953, but lost CBS programming to KLZ-TV when that station signed on in November of that year; this was followed by the loss of the NBC affiliation to KOA-TV when it signed on a month later (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). This left KBTV as a primary DuMont and secondary ABC affiliate. It would become a full-time ABC affiliate when DuMont ceased operations in 1956. To adapt to the loss of network programming during this transition, station management emphasized local productions. In February 1953, the station began airing a weekly program sponsored by the
Denver Bears baseball team. Long before the establishment of the
Denver Broncos, KBTV served as the outlet for
National Football League games, broadcasting
Chicago Bears and
Chicago Cardinals home games on Sundays. The station also engaged in significant public service efforts early on. In April 1953, KBTV broadcast a 14-hour telethon for
United Cerebral Palsy, featuring national personalities like
Dennis James and raising $125,000. The event became an annual tradition, with the second iteration in 1954 featuring
Warren Hull and utilizing over 1,000 volunteers. However, local programming did not always meet with viewer approval. In January 1954, a broadcast of a horse show and rodeo drew complaints for excessive interruptions by commercials and interviews. Station producer Everett Wren publicly acknowledged the criticism, stating the station was still learning how to balance coverage for such events. In late 1953, amidst public speculation about the arrival of
color broadcasting, KBTV aired a five-week series titled
Debunking Color. The program, moderated by station executives and electrical league officials, was designed to explain the technical and economic obstacles remaining before color television could become a reality in Denver.
Mullins ownership (1955–1959) In March 1955, the FCC approved the sale of KBTV from the Colorado Television Company to TV Denver, Inc. for $900,000. The new ownership group was led by John C. Mullins of
Tulsa, Oklahoma, and Frank R. Leu of
Nashville, Tennessee, each holding a 50 percent interest. The sale separated the television station from its original radio partner, KVOD. Under Mullins' ownership (later organized as Mullins Broadcasting), the station would eventually form a radio news partnership with KBTR (now
KNUS) that lasted until the mid-1980s. Upon taking over in 1955, Mullins faced a station losing approximately $25,000 per month. He implemented changes that eventually turned the operation profitable, with the station's valuation reportedly rising to $3.5 million by 1958. The ownership structure shifted again in 1956 when Leu petitioned the FCC to transfer his 50 percent interest to the New York–based real estate firm
Webb & Knapp, headed by
William Zeckendorf. Under this arrangement, Zeckendorf became chairman of the board while Mullins remained president. During this period, the station explored relocating its facilities. In late 1955, KBTV abandoned a $100,000 remodeling project at its Bannock Street studios amid rumors of a move to the Courthouse Square development. By 1957, plans were announced to move the station's studios into the Denver Hilton hotel (now the Sheraton Denver Downtown Hotel), then under construction by Zeckendorf's firm. The proposed facility was to occupy on two sub-surface levels. However, in April 1959, these plans were canceled when the hotel space was reallocated for a ballroom and exhibit hall. Consequently, Mullins announced that the station would instead remodel and expand its existing headquarters at 1089 Bannock Street. In November 1955, KBTV entered a partnership with
The Denver Post to produce a daily afternoon news segment. The program featured
Post editors and reporters presenting stories directly from the newspaper's newsroom, a collaboration described by publisher Palmer Hoyt as a "joint endeavor" between competing media. The station also expanded its local coverage with the launch of
Crime Report, Denver in 1956 and the first televised coverage of the
Lakeside Amusement Park fireworks display that July. In January 1957, KBTV began broadcasting daily highlights of the
National Western Stock Show. This marked the beginning of a broadcasting tradition that the station (now KUSA) has continued annually to the present day. In April 1959, the station secured rights to televise nine Denver Bears baseball games, utilizing a five-camera setup to boost interest in the team. As an ABC affiliate, KBTV benefited from the network's ratings surge in the late 1950s, driven by the popularity of westerns such as
Maverick. However, the station drew significant viewer ire in March 1959 during a broadcast of a championship fight between
Archie Moore and
Hogan Bassey. When the fight ended abruptly in the 13th round, the station cut away to a scheduled block of local commercials rather than showing the official decision or explaining the fight's conclusion, leading to a deluge of complaints. In September 1957, Mullins submitted an informal application to the Denver City Council seeking authority to introduce a
subscription television service. The proposal outlined potential delivery methods, including wire systems or scrambled air signals, to offer exclusive programming such as major sports and theatrical productions. Like other Denver stations, KBTV's operations were severely impacted by a massive blizzard in April 1957. A power line failure on Lookout Mountain knocked the station off the air for nearly 20 hours, with engineers snowshoeing into the transmitter site to restore operations. Tragedy struck the technical staff the following year; in December 1958, engineer Joe Pershin died of a cerebral hemorrhage while installing microwave equipment on a rooftop for a remote telecast.
Combined and Gannett ownership (1972–1995) In 1972, Mullins Broadcasting sold KBTV and sister station
KARK-TV (channel 4) 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 (channel 12, now
KPNX-TV). Combined's station properties would eventually be merged into the
Gannett Company seven years later in May 1978, in what was the largest media merger in United States history at the time. In order to align itself with Gannett's new newspaper entity
USA Today, the station changed its call letters to KUSA-TV on March 19, 1984 (
Minneapolis–Saint Paul sister station WTCN underwent a similar rebranding in 1985, when it changed its call letters to WUSA; however, after Gannett purchased
Washington, D.C. station WDVM-TV in 1986, it moved the
WUSA call letters to its newly acquired station; the Minneapolis station that originally held the WUSA calls was renamed
KARE-TV). The
KBTV call letters are now at a station in
Beaumont, Texas. In April 1992, KUSA 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]).
NBC affiliation (1995–present) On July 14, 1994, as a result of an affiliation agreement between the
E. W. Scripps Company and ABC that was spurred by
Fox's affiliation deal with
New World Communications, CBS and
Westinghouse Broadcasting (Group W) agreed to a long-term affiliation deal that saw longtime ABC affiliate
WJZ-TV in
Baltimore and longtime NBC affiliates
KYW-TV in
Philadelphia and
WBZ-TV in
Boston become CBS affiliates. Westinghouse's other two stations,
KDKA-TV in
Pittsburgh and
KPIX-TV in
San Francisco, were already longtime CBS affiliates. That November, NBC traded KCNC-TV, which was the network's
owned-and-operated station at the time, to CBS in return for CBS's former O&O in Philadelphia,
WCAU, as a result of a complex ownership deal between the network, Westinghouse and NBC. CBS had originally planned to sell WCAU to NBC as part of its plan to move its affiliation to KYW-TV, but discovered that an outright sale would incur heavy
capital gains taxes on proceeds from the deal. To make the transaction a legal trade, the network swapped ownership of KCNC-TV and
KUTV in
Salt Lake City (which NBC had acquired earlier that year), along with the VHF channel 4 frequency and transmitter in
Miami (then home to
WTVJ), to CBS in exchange for WCAU and the channel 6 frequency in Miami (then home to WCIX, which subsequently became
WFOR-TV). Gannett then signed a multi-station affiliation agreement with NBC that included KUSA. This resulted in all three of Denver's "Big Three" stations swapping affiliations at 12:07 a.m. on September 10, 1995, which resulted in KUSA switching to NBC, KMGH switching to ABC, and KCNC switching to CBS; Westinghouse had purchased CBS in a group deal one month before, making KCNC a CBS owned-and-operated station when the deal was finalized on November 24 of that year. The final ABC program to air on channel 9 was a repeat of the
ABC Saturday Night at the Movies feature
Gremlins 2: The New Batch, on September 9, 1995. 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. As a result, most cable providers in that region began piping in KUSA. Channel 9 served as the
market's default NBC affiliate until 1998, when
KNBN-LP signed on as the network's new affiliate for the Black Hills region; that station was not carried on cable until it was upgraded to full-power as
KNBN on May 14, 2000. In August 2007, KUSA began the "9NEWS High School Hotshots Program", which awarded one of twelve student athletes from Colorado's high schools nominated for their academic excellence, selected by the school's administration and staff that recorded their
high school football games; the program has since extended to cover winter sports at the schools. 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. On June 29, 2015, the Gannett Company split in two, with one side specializing in print media and the other side specializing in broadcast and digital media. KUSA and KTVD were retained by the latter company, named
Tegna. On August 19, 2025,
Nexstar Media Group agreed to acquire Tegna for $6.2 billion. In Denver, Nexstar already owned
KDVR (channel 31) and KWGN-TV. The deal was approved and completed on March 19, 2026. As part of the transaction, Nexstar committed to the divestiture of KTVD within two years, along with five other stations in markets where the two companies combined held four TV station licenses. KUSA continues to operate separately from KDVR as the legality of the merger is challenged, with
Phil Weiser of Colorado among eight state attorneys general who have filed to block the deal. ==Programming==
