KWTV-DT (channel 9) is a television station in Oklahoma City, Oklahoma, United States, affiliated with CBS. It is the flagship broadcast property of locally based Griffin Media, and is co-owned with MyNetworkTV affiliate KSBI (channel 52). The two stations share studios on West Main Street in downtown Oklahoma City; KWTV-DT's transmitter is located on the city's northeast side.

John Toole "J. T." Griffin—the owner and president of the Griffin Grocery Company, a Muskogee-based wholesaler and manufacturer of condiments and baking products, states that he inherited from his father, John Taylor Griffin, after the elder company co-founder died in 1944—became interested in television broadcasting around 1950, after noticing during one of his commutes that many homes in the Oklahoma City area had installed outdoor antennas to receive the signal of primary NBC affiliate WKY-TV (channel 4, now KFOR-TV), the first television station ever to sign on in Oklahoma, which began operation on June 6, 1949. In an effort to secure a grant to operate a television station in Oklahoma City, Griffin—who first entered the broadcasting industry in October 1938, when he purchased local radio station KOMA (1520 AM, now KOKC) from Hearst Radio for $315,000—filed competing construction permit/license applications to the Federal Communications Commission (FCC) under two separate companies in which he held ownership interests.

On September 5, 1951, the Oklahoma Television Corporation—a consortium led by Griffin (who, along with sister Marjory Griffin Leake and brother-in-law James C. Leake, became the company's majority owners in July 1952, with a collective 92.7% controlling interest) and investors that included former Oklahoma Governor Roy J. Turner, company executive vice president Edgar T. Bell (who would later serve as channel 9's first general manager), and Video Independent Theatres president Henry Griffing (who acted as a trustee on behalf of the regional movie theater operator)—filed an application for a construction permit to build and license to operate a television station on VHF channel 9. On June 27, 1952, KOMA Inc., a licensee corporation of KOMA radio that was largely owned by Griffin and the Leakes, filed a separate application to operate channel 9. The FCC eventually granted the license to the Oklahoma Television Corporation on July 22, 1953, after the company struck an agreement with KOMA Inc. days prior to merge their respective bids, in exchange for KOMA purchasing 50% of the shares in Oklahoma Television that were owned by that group's original principal investors. (Under FCC procedure, the Commission's Broadcast Bureau board decided on license proposals filed by "survivor" applicants at the next scheduled meeting following the withdrawal of a competing bid.) Instead of using the KOMA calls assigned to the radio station, the Griffin group chose instead to request KWTV (for "World's Tallest Video") as the television station's call letters, in reference to the transmission tower that was being built behind its studio facility (which was also under construction at the time) on open land near Northeast 74th Street and North Kelley Avenue; the land plot was purchased by KOMA in 1950, with the intention of developing it for a television broadcast facility. (KOMA would vacate its facilities at the now-demolished Biltmore Hotel in downtown Oklahoma City once the Kelley Avenue building was completed.)

After conducting initial test pattern transmissions beginning on December 8, KWTV officially signed on the air on December 20, 1953. The station's first broadcast was a special 30-minute ceremony inaugurating channel 9's launch at 7 p.m. that evening, respectively featuring speeches from Griffin, Bell and Turner, announcements of station policies, and an introduction of station stockholders and employees. KWTV was the third and last commercial television station to sign on in the Oklahoma City market during 1953: two UHF stations—KTVQ (channel 25, allocation now occupied by Fox affiliate KOKH-TV), an ABC affiliate that launched on October 28, and KLPR-TV (channel 19, allocation now occupied by Cornerstone Television affiliate KUOT-CD), a DuMont Television Network affiliate that debuted on November 8—would eventually cease operations within three years of their respective debuts. Originally broadcasting daily from 6 a.m. to midnight, channel 9 has been a CBS television affiliate since its debut (WKY-TV aired select CBS programming until November 14); the affiliation owed to KOMA radio's longtime partnership with the CBS Radio Network, which had been affiliated with its then-radio sister since 1929. KWTV also maintained a secondary affiliation with DuMont, from which WKY-TV had also carried selected programs, until the network discontinued operations in August 1956. On October 15, 1956, KWTV began carrying programming from the NTA Film Network; channel 9 served as the programming service's secondary Oklahoma City affiliate, offering a limited schedule of drama and comedy series. (Most of NTA other shows were shown on WKY-TV, while ABC affiliate KGEO-TV only aired its NTA Film Spectacular anthology series.) This relationship lasted until National Telefilm Associates discontinued the service in November 1961, when KWTV became exclusively affiliated with CBS.

Channel 9—which is one of the few television stations in the United States to have had the same callsign, ownership, primary network affiliation and over-the-air channel allocation throughout its history—temporarily transmitted its signal from KOMA's 300-foot (91 m) broadcast tower near the television station's Kelley Avenue studios. KWTV activated its permanent transmission facility in September 1954; at 1,572 feet (479 m), the tower—which cost $650,000 to construct and weighed 525 short tons (476 t)—became the tallest man-made structure and the tallest free-standing broadcast tower in the world at that time. (It would be surpassed for the title in December 1956, when Roswell, New Mexico-based KSWS-TV [now KOBR] activated a 1,610-foot [490 m] guy-wired tower in Caprock, New Mexico.) To commemorate the new tower, an event that KWTV management estimated had 5,000 attendees, an amateur photography competition was held in which the winning pictures of the tower (with photography equipment donated by local camera stores being awarded to the finalists) would be chosen for inclusion in station publicity advertisements. A young Johnny Carson, then the host of the CBS game show Earn Your Vacation, served as master of ceremonies for the tower's dedication. The Oklahoma Educational Television Authority (OETA)—which, per an agreement with the Oklahoma Television Corporation, was granted free use of the land near the KWTV studio and transmitter—became a tenant on the tower in April 1956, when the educational broadcaster's flagship station KETA-TV (channel 13) activated its transmitter. (The tower was decommissioned following the transition of KWTV and KETA to digital-only broadcasts in the spring of 2009, as their digital transmitters were located on a separate tower between 122nd Street and the John Kilpatrick Turnpike; the antenna and the upper half of the tower were physically disassembled by engineers and crane equipment during the summer of 2014, and its remnant sections were imploded that October.) The station relocated its operations into its new Kelley Avenue studio facility on October 17, 1954.

Some of the local programs that channel 9 produced over the years have included the children's program Miss Fran from Storyland, in which host Fran Morris—who hosted the show from 1958 to 1967, during her tenure as KWTV's director of educational programming, before moving to WKY-TV/KTVY to host the similarly formatted Sunday Morning with Miss Fran for an additional 17 years—told children's stories, conducted arts and crafts demonstrations, displayed viewer-submitted artwork on a "storyboard," and occasionally showcased Davey and Goliath animated shorts; The Gaylon Stacy Show, a half-hour morning talk-variety program—whose host had also helmed two other shows during his tenure at KWTV, the Saturday morning children's show Junior Auction and the variety-game show You Name It—that ran from 1960 to 1970, which featured live guests and on-location celebrity interviews; and Foods 'n Focus, a five-minute-long, Oklahoma Natural Gas-produced cooking show hosted by Jane Frye that ran from 1973 to 1977. The Griffin-Leake interests sold KOMA (which, as of 2019^[update], is now owned by Oklahoma City-based Tyler Media) to Radio Oklahoma, Inc.—an investor-owned group led by radio executive Burton Levine—on November 20, 1956, for $342,500, but chose to retain ownership of KWTV.

Over the years, the Griffin family owned other television stations in Oklahoma and Arkansas. On December 15, 1953 (five days before KWTV signed on), the Griffin-Leake partnership launched their first television station, ABC affiliate KATV in Little Rock, Arkansas; the group would later sign on their second ABC-affiliated station, KTVX (now Tulsa-based KTUL) in Muskogee, on September 18, 1954. Post-split from Leake, Griffin Television bought NBC affiliate KPOM-TV (now Fox affiliate KFTA-TV) in Fort Smith from Ozark Broadcasting Co. in September 1985; then in October 1989, it signed on KFAA (now KNWA-TV) in Rogers as a satellite station serving Fayetteville and other areas of northwest Arkansas that could not receive KPOM's signal. (KPOM and KFAA were owned by the Griffins until 2004, when it sold the two stations to the Nexstar Broadcasting Group.) Griffin Communications re-entered the Tulsa market with its October 2000 purchase of fellow CBS affiliate KOTV from the Belo Corporation; Griffin gained a second station in that market when it purchased Muskogee-based WB affiliate KWBT (now CW affiliate KQCW-DT) from Cascade Broadcasting Group in October 2005.

In April 1961, Triarko Ltd.—a subsidiary of RKO General—purchased a controlling stake in Video Independent Theatres from the estate of the late Henry Griffing. On paper, the 12.5% interest in KWTV included in the deal effectively gave RKO its fifth VHF television station, putting it at the maximum then allowed under FCC ownership rules (alongside its wholly owned station properties in New York City, Los Angeles, Boston and Memphis as well as a controlling stake in a Canadian station in Windsor, Ontario, that dually served the Detroit market). This created an issue for a then-ongoing and complex transaction in which RKO was to have acquired WRC-TV and WRC-AM-FM (now WTEM and WKYS) in Washington, D.C., from NBC, trade WNAC-TV (now defunct; former channel allocation now occupied by WHDH), WNAC-AM (now WRKO) and WRKO-FM (now WBZ-FM) in Boston to NBC in exchange for the WRCV television and radio stations (now KYW-TV and KYW (AM)) in Philadelphia, and sell the Washington-based WGMS radio stations (now WWRC and WTOP-FM) to Crowell-Collier Broadcasting. Philco—which protested the 1957 license renewal of WRCV-TV-AM to NBC amid questions over the legality of its purchase of the stations from Westinghouse in exchange for WTAM-AM-FM and WNBK television (now WKYC) in Cleveland the year before—took issue with whether RKO's interest in KWTV violated FCC ownership rules. Addressing this, in August 1962, RKO agreed to sell its stake in channel 9 to minority stockholders Roy Turner and Luther Dulaney, increasing their individual interests in the station to 18.75%.
