KPIX-TV, channel 5, is a CBS owned-and-operated television station located in San Francisco, California, USA. The station is owned by the CBS Television Stations subsidiary of CBS Corporation, and is part of a duopoly with CW owned-and-operated station KBCW (channel 44). The station's studios are located just north of San Francisco's Financial District, and its transmitter is located on Sutro Tower. In addition to KBCW, KPIX shares its studios with its CBS Radio partners: KCBS, KFRC-FM, KITS, KLLC, KMVQ-FM and KZDG, although they use a different address number for Battery Street (865 as opposed to 855). In the few areas of the western United States where a CBS station is not receivable over-the-air, KPIX is available to Dish Network customers as part of All American Direct's distant network package. ==History== KPIX-TV signed on the air on December 22, 1948 as the first television station in northern California, as well as the 49th in the United States. It was originally owned by Associated Broadcasters, owners of KSFO (560 AM). Initially, channel 5's signal was transmitted from a tower on top of the Mark Hopkins Hotel on Nob Hill. It later moved to a shared transmitter tower with KGO-TV at the Sutro Mansion (which was located midway between Mount Sutro and Twin Peaks), and then to the Sutro Tower in 1973. KPIX's first studio was in the attic of the Mark Hopkins Hotel (just above the "Top of the Mark"). The station immediately joined CBS due to a deal KSFO's owners had worked out with the television network one year earlier. KSFO was CBS radio's Bay Area affiliate from 1937 to 1941, when Associated Broadcasters backed out of a deal for CBS to buy the station. When KSFO was still affiliated with CBS, it was originally slated to move to 740 AM, the dial position of San Jose's KQW. 740 AM was the last 50,000-watt frequency available in the Bay Area, and KSFO was to raise its power to 50,000 watts after moving to 740. However, after KSFO parted ways with CBS radio, the network moved its Bay Area affiliation to KQW and was not about to give up the advantage of owning the Bay Area's last available 50,000-watt station. After lengthy Federal Communications Commission (FCC) hearings, KSFO won the 740 frequency, but later decided to stay at 560 and concentrate its efforts on building a television station. It traded the 740 frequency to CBS in return for getting the CBS television affiliation for the Bay Area. KQW remained at 740 and CBS changed its call sign to KCBS. The station also carried programming from DuMont until that network folded in 1956.〔 It even carried a few NBC programs until KRON-TV signed on in November 1949, and programs from the short-lived Paramount Television Network, such as ''Frosty Frolics'', ''Time For Beany'', ''Cowboy G-Men'' and ''Bandstand Revue''. When KPIX's first competitor, KGO-TV, signed on in May 1949, KPIX produced programs to welcome it into the Bay Area. KPIX cameras were used on the first episode of the CBS News program ''See It Now'' on November 18, 1951, which opened with the first live simultaneous coast-to-coast TV transmission from both the East Coast (the Brooklyn Bridge and New York Harbor) and the West Coast (KPIX-produced images of the Golden Gate Bridge and San Francisco Bay), under the narration of Edward R. Murrow. Under its first general manager, Phil Lasky, KPIX gained an early reputation for news coverage, being noted for originating national CBS coverage of the Japanese Peace Conference of 1951 (the event which "officially" brought an end to World War II, similar to the function that the Treaty of Versailles served for World War I), held in San Francisco (for which Lasky was commended by then-CBS News president Sig Mickelson), as well as local news coverage of the 1953 crash of an Australian airliner while on approach to San Francisco International Airport, and a powder explosion a few weeks afterward at an explosives plant in suburban Hercules. In regards to sports programming, KPIX originated the annual college football East-West Shrine Game for DuMont, and was the flagship station of the San Francisco Seals of the Pacific Coast League until 1954. In 1952, KPIX and KSFO moved into a new building at 2655 Van Ness Avenue; KPIX moved out of the facility in 1979, when it relocated to a converted 1920s era warehouse on the corner of Battery and Broadway streets (refurbished by the architecture firm Gensler), where KPIX remains to this day (KSFO moved to studios in the Fairmont Hotel, across the hall from the Tonga Room, later in the 1950s). The studio on Van Ness Avenue was the first building in San Francisco specifically built for television (it was demolished in 2006 to make way for a condominium complex〔(【引用サイトリンク】title=San Francisco Radio - KSFO/KPIX Studios )〕). Westinghouse Electric Corporation bought KPIX in 1954 and ran it as part of the company's Group W broadcasting unit.〔"Six stations being sold for nearly $15 million." ''Broadcasting - Telecasting'', March 8, 1954, pp. 27-28. () ()〕 During Westinghouse's ownership, KPIX was the company's only television station on the West Coast. Additionally, it was one of two VHF stations (along with Pittsburgh's KDKA-TV) that didn't have a historic three-letter callsign, the only one to have a "K" callsign west of the Mississippi River, and along with WJZ-TV in Baltimore (until 2008) was the only one without a sister radio station with matching callsigns. In early 1996, Westinghouse merged with CBS, making KPIX a CBS-owned station and bringing it into common ownership with KCBS radio. Prior to this, KPIX had been CBS's longest-tenured affiliate (a distinction that now belongs to Washington, D.C.'s WUSA). KPIX was also one of two longtime CBS affiliates owned by Group W that became a CBS O&O, the other being KDKA-TV. Since May 2003, KPIX-TV and WJZ-TV are the only former Group W TV stations that still utilize the classic Group W font. In May 2006, KPIX moved its San Jose news bureau to the Fairmont Tower at 50 W. San Fernando Street – which served as the original site of Charles Herrold's experimental radio broadcasts that were the precursor of KCBS. Although CBS was not aware of the significance of the San Fernando St. address when the move was planned, it quickly recognized and embraced its significance when informed, giving long-overdue credit to one of the inventors of radio broadcasting during the bureau's opening celebration. 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「KPIX-TV」の詳細全文を読む スポンサード リンク
