:''This article is about the television station in Perth, Western Australia. For other channels known as TVW, see TVW (disambiguation).'' TVW is a television station broadcasting in Perth, Western Australia, wholly owned by the Seven Network, whose principal owner is Perth-born Kerry Stokes. It was the first television station in Western Australia, commencing service on 16 October 1959. It broadcasts a digitally modulated 64-QAM signal of four DVB channels (Seven Network, 7Two, 7Mate and TV4ME) on VHF channel 6 at 177.5 MHz from Bickley in the Perth Hills. The primary channel was available as a PAL-B modulated simulcast on VHF channel 7 at 182.25 MHz before being discontinued in the first half of 2013, which was the station's primary signal since its inception. The TVW callsign stands for Television Western Australia. ==History== On 13 October 1958, the first commercial television license in Perth was granted by the Minister for Posts and Telegraphs to TVW Limited, a subsidiary of West Australian Newspapers (WAN), publisher of Perth's daily newspaper, ''The West Australian''. TVW commenced broadcasting a little over a year later, on 16 October 1959. The then Governor of Western Australia, Sir Charles Gairdner opened the station at 7.30pm that night. Some of the first programs included ''Leave It to Beaver'', ''Sea Hunt'', ''Father Knows Best'', ''Gunsmoke'', ''Perry Mason'', ''The Epilogue'' and a local show called ''Spotlight'' which featured Rolf Harris. The signal was broadcast from the station's transmitter site at Bickley in the Darling Ranges. TVW-7 did not have a rival commercial television station until 1965 when STW-9 commenced broadcasting. However the presence of a rival did not have a large negative impact on TVW, at least in the early years. In fact a survey by its rival found that more people agreed with a statement that "TVW fulfilled their viewing needs, and it would be a matter of indifference to them if the new station were to cease transmissions".〔()〕 The advantage TVW built up in its six years as sole commercial operator flowed through for many more years to come, some would even argue that it is still present today considering how well Seven performs in the market compared to Nine, which for nearly two decades until the mid-2000s, generally won comfortably nationally. After STW-9 entered the market, a 'cartel' was formed between the two stations for the duty of buying from both Australian and overseas production sources. The two stations set up a separate company, TV Facilities, (50%/50% partners). This allowed the stations to purchase programs cheaper than if they were two separate entities, which would bid on shows and subsequently raise prices. This partnership was disliked by Eastern States stations who could not increase their charges to the extent which they would have liked. Allocation of programs was decided by a coin toss, which would allow the winner to pick first and then alternate the picking of programs. However TVW would always be in a more dominant position as it had the rights to continuing shows from the previous six years as well as half of the new programs. In 1971 TVW Enterprises purchased SAS-10 in Adelaide, now SAS-7. Eight years later, TVW finally took on an affiliation, aligning with the Seven stations in the East. 1982 saw TVW (and SAS) purchased by Perth-based businessman Robert Holmes à Court’s Bell Group. This soon posed a problem for SAS, since Network Ten officials were unwilling to discuss network plans with Bell given that it owned a Seven affiliate. To solve this problem, SAS swapped affiliations and frequencies with Adelaide's original Ten affiliate, ADS, in 1987. In 1988, Perth finally got full network service when NEW signed on and aligned with Ten. 1988 also saw the station change hands when the Christopher Skase led Qintex group purchased the station. Qintex collapsed a year later, leaving TVW in the hands of receivers. In 1991 the network was floated on the stock exchange and by 1995 Perth-born Kerry Stokes was in charge of both TVW and the rest of the network. Since then, the station has continued to enjoy a dominant share of television ratings in the Perth market. TVW commenced digital television transmission in January 2001, broadcasting on VHF Channel 6 while maintaining analogue transmission on VHF Channel 7. The analogue signal for TVW was shut off at 9.00am WST, Tuesday, 16 April 2013. Stokes bought a 15 percent stake in West Australian newspapers in 2006. In 2011, West Australian Newspapers bought the Seven Network to form Seven West Media, thus fully reuniting TVW with its founding owner. In February 2015, TVW moved from their original broadcasting facility in Gay Street, Dianella to a new HD broadcast centre in Osborne Park located within West Australian Newspapers. 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「TVW」の詳細全文を読む スポンサード リンク
