KWTV-DT, virtual channel 9 (UHF digital channel 39), is a CBS-affiliated television station located in Oklahoma City, Oklahoma, United States. It is the flagship television station of locally based Griffin Communications as part of a duopoly with MyNetworkTV affiliate KSBI-TV (channel 52). The two stations share studio facilities located on Kelley Avenue (adjacent to the studios and main offices of the Oklahoma Educational Television Authority PBS member network), and its transmitter is located near the John Kilpatrick Turnpike/Interstate 44, both on the city's northeast side. ==History== John Toole Griffin, a local grocery magnate and founder of Griffin Foods, decided to apply for a broadcast license with the Federal Communications Commission after noticing while driving around Oklahoma City that many homes in the area had outdoor television antennas installed to receive WKY-TV (channel 4, now KFOR-TV), which debuted in June 1949 as the first television station in Oklahoma.〔Interview with Griffin Communications president David Griffin from the "KWTV 50th Anniversary Special", 2003.〕 KWTV first signed on the air on December 20, 1953; it was founded by Griffin and his brother-in-law James C. Leake, co-owners of radio station KOMA (1520 AM, now KOKC). Channel 9 initially transmitted its signal from a shorter temporary tower near its Kelley Avenue studios as its permanent transmitter tower, for which the Griffins chose the KWTV callsign (standing for "World's Tallest Video") for the station over using the KOMA calls, was still under construction; when it was activated in 1954, the structure became the tallest free-standing broadcast tower in the world at the time. As of October 2014, the tower is currently being removed and sold for scrap. KWTV's first broadcast was a roll call of station employees introducing themselves and the departments they were employed with.〔Interview with longtime KWTV employee Spec Hart from "KWTV 50th Anniversary Special", 2003.〕 KWTV has been a CBS affiliate since its sign-on (having taken the affiliation from WKY-TV, which relegated the network to secondary clearances), owing to KOMA's longtime affiliation with the CBS Radio Network; it is one of the few American television stations that has had the same callsign, ownership, primary network affiliation and over-the-air channel allocation throughout its history. Todd Storz, creator of the Top 40 radio format, purchased KOMA in 1958. Griffin and Leake bought out the partners that held minority interest in KWTV in 1963; Leake then sold his interest to Griffin in 1968, in return for Griffin's share of two other television stations, KTUL in Tulsa and KATV in Little Rock. By the 1970s, KWTV became the first station in Oklahoma City to record news footage on videotape instead of film. In the late 1970s, it also became the market's first television station to maintain a 24-hour programming schedule. John Griffin retired in 1990, and turned over control of channel 9 to his son David. On August 18, 1993, KWTV partnered with Cox Cable and Multimedia Cablevision to create a 24-hour local cable news channel through a condition in carriage renewal agreements between Griffin Television and the two cable providers.〔(TV Station, Cable Operators to Provide Local Broadcast Cable Channel ), Knight Ridder/Tribune Business News / ''The Daily Oklahoman'' (via HighBeam Research), August 18, 1993.〕 This channel, News Now 53, debuted locally on December 3, 1996 on Cox channel 53, featuring rebroadcasts and live simulcasts of KWTV's news programs (News Now 53 was initially available only in Oklahoma City proper, expanding to its outlying suburbs after Cox acquired Multimedia Cablevision from the Gannett Company in January 2000); a Tulsa area feed of News Now 53 launched in 2000 after Griffin purchased that market's CBS affiliate, KOTV. On January 26, 2001, a Beechcraft Super King Air 200 transporting nine members of the Oklahoma State University basketball team (including two players and six members of the coaching staff) and KWTV sports director Bill Teegins (who was also the university's football and basketball radio announcer) crashed in a field near Strasburg, Colorado.〔(Witness of Oklahoma State University plane crash describes 'ball of fire' ), CNN, January 28, 2001.〕 The plane departed from Jefferson County Airport following a game against the University of Colorado Buffaloes, when the pilot became disoriented while flying through heavy snow on the way to Stillwater Regional Airport; all ten men on board were killed (two memorials have since been erected in remembrance of the tragedy: one at the crash site, and another outside of Gallagher-Iba Arena at OSU's Stillwater campus featuring a statue of a kneeling cowboy).〔(N81PF accident description )〕 Also in 2001, KWTV entered into a content partnership with ''The Oklahoman'', resulting in the merger of both the station and newspaper's websites under the "(NewsOK )" banner; this collaboration ended in early 2008 (the NewsOK website continues to exist as the standalone website for ''The Oklahoman''). Ironically the Gaylord family, who ran the newspaper from 1907 to 2011 (when the paper's owner, OPUBCO Communications Group, was sold to The Anschutz Corporation), built and signed on competitor KFOR-TV in 1949, and owned that station until 1975. On October 25, 2010, KWTV became the first television station in the Oklahoma City market to carry syndicated programming and advertisements inserted during local commercial breaks (including station and network promos) in high definition. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「KWTV-DT」の詳細全文を読む スポンサード リンク
