CITY-DT, virtual channel 57 (UHF digital channel 44), is a City owned-and-operated television station located in Toronto, Ontario, Canada. The station is owned by Rogers Media, a division of Rogers Communications (through its Rogers Broadcasting Limited division), as part of a triplestick (the only conventional television triplestick operated by the company) with Omni Television stations CFMT-DT (channel 47) and CJMT-DT (channel 40). The three stations share studio facilities located at 33 Dundas Street East on Yonge-Dundas Square in downtown Toronto; CITY maintains transmitter facilties located atop the CN Tower in downtown Toronto. On cable, CITY is also available on corporate sister Rogers Cable channel 7 and digital channel 133; on satellite, the station is available on Bell TV channel 214. There is also a high definition feed on Rogers Cable digital channel 519 and Bell TV channel 1053. The station was best known for its unconventional approach to news and other locally produced programming, creating the basis upon which the City television network (of which CITY-DT serves as the flagship station) was built. ==History== The station first signed on the air on September 28, 1972, broadcasting on UHF channel 79, an allocation given to the station as all of the VHF licences in the Toronto area were taken by other parties. It operated as an independent station, and its transmitter operated at an effective radiated power of 31 kW. The founding ownership group Channel Seventy-Nine Ltd. consisted of – among others – Phyllis Switzer, Moses Znaimer, Jerry Grafstein and Edgar Cowan. The four principal owners raised over $2 million to help start up the station, with Grafstein raising about 50% of the required funds, Znaimer raising around 25%, and the remainder being accrued by Switzer and Cowan. The channel 79 licence was granted to the company on November 25, 1971.〔(Genesis, Genius and Tumult at Citytv Recalled 40 Years On ), ''Broadcaster Magazine'', October 1, 2012.〕 The station operated from studio facilities located at 99 Queen Street East, near Church Street, at the former Electric Circus nightclub. The station lost money early on, and was in debt by 1975. Multiple Access Ltd. (the owners of CFCF in Montreal) purchased a 45% interest in the station, and sold its stake to CHUM Limited three years later. CITY was purchased outright by CHUM in 1981 with the sale of Moses Znaimer's interest in the station. Znaimer remained with the station as an executive until 2003, when he retired from his management role but continued to work with the station on some production projects.〔(Znaimer steps down as president of CHUM TV ), ''Broadcaster Magazine'', April 27, 2003.〕 In 1976, the station's main transmitter began broadcasting at 208 kW from the CN Tower. The station switched channel allocations on July 1, 1983, moving to UHF channel 57, the result of Industry Canada's decision to reassign frequencies corresponding to high-band UHF channels 70 to 83 to the new AMPS mobile phone systems as a result of a CCIR international convention in 1982. On September 1, 1986, a rebroadcast transmitter was put into operation in Woodstock (CITY-TV-2 on channel 31, which also served nearby London); another transmitter was set up in Ottawa in 1996 (CITY-TV-3 on channel 65). In 1987, CITY and the other CHUM-owned television properties moved their operations to the company's headquarters at 299 Queen Street West, which became one of the most recognizable landmarks in the city. On March 30, 1998, CHUM launched CablePulse 24 (CP24), a local cable news channel whose programming used anchors from and featured reports filed by CITY-TV's news staff, rebroadcasts of the station's ''CityPulse'' newscasts and select programming from CITY and other CHUM stations. Despite efforts to extend the brand to other major markets, for 30 years, CITY was the only Canadian station to identify on-air as "Citytv" – with "Citytv" and "CITY" serving as interchangeable names for the station. In July 2001, however, CHUM purchased CKVU-TV in Vancouver from Canwest Global Communications; CKVU changed its branding to "Citytv" in July 2002, making Citytv a two-station system. In 2005, three more Citytv stations were added in Calgary (CKAL), Edmonton (CKEM) and Winnipeg (CHMI) after CHUM purchased the A-Channel television stations and other assets owned by Craig Media (the existing A-Channel brand was revamped and was transferred to CHUM's former NewNet stations). When the three A-Channel stations switched to the Citytv brand on August 2, 2005, the flagship City''Pulse'' newscast was renamed City''News''. 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「CITY-DT」の詳細全文を読む スポンサード リンク
