Iowa Public Television (IPTV) is a network of Public Broadcasting Service (PBS) member stations in the state of Iowa. IPTV is owned by the Iowa Public Broadcasting Board, an agency of the state education department which holds the licenses for all the PBS member stations in the state. IPTV's studios are located in Johnston, Iowa; a suburb of Des Moines. ==History== Iowa is a pioneer in educational broadcasting; it is home to two of the oldest educational radio broadcast stations in the world, the University of Iowa's WSUI and Iowa State's WOI. The electrical engineering department at the State University of Iowa (SUI) in Iowa City demonstrated television at an exhibit at the Iowa State Fair in Des Moines on August 28, 1931. J. L. Potter supervised the project. At the conclusion of the Iowa State Fair, the television experiment was set up in the communications laboratory of the electrical engineering building at The University of Iowa in Iowa City. By 1933, The University of Iowa received an FCC license for experimental TV station W9XK, later W9XUI providing twice a week video programming, with WSUI AM providing the audio channel. By 1939, the FCC allocated TV channels 1 and 12 for the W9XUI television station. This early attempt at educational broadcasting ended with US entrance into World War II. The concept of pure educational television, which Dr. E.B. Kurtz and his Iowa colleagues pioneered, was buried by the commercial television system which dominated development of the electronic media in Iowa after World War II.〔(【引用サイトリンク】title=The Untold Story, W9XK - Iowa City )〕 WOI-TV in Ames began broadcast operations in 1950, as a sister station to WOI radio, and had carried some National Educational Television programming until Des Moines Public Schools signed on KDPS-TV as the educational station for central Iowa in 1959. However, in the 1960s the only other areas of the state with a clear signal from an educational station were the southwest (from Nebraska ETV's KYNE-TV in Omaha), the northwest (from South Dakota ETV's KUSD-TV in Vermillion), and in eastern Iowa from The University of Iowa's WSUI-TV in Iowa City. In 1969, the state of Iowa bought KDPS-TV from the Des Moines Public Schools and changed its calls to KDIN-TV, intending it to be the linchpin of a statewide educational television network. As part of the state's ambition, it rebranded KDIN as the Iowa Educational Broadcasting Network. The network's second station, KIIN-TV in Iowa City〔(【引用サイトリンク】title=Early Television Stations in U.S. )〕 had resumed broadcast operations in 1950 from Iowa City as WSUI-TV on channel 12. WSUI-TV joined IEBN in 1970 to expand statewide educational programming to eastern Iowa and northwestern Illinois. Soon afterward, IEBN became a charter member of PBS. By 1977 the newly renamed Iowa Public Broadcasting Network had eight full-power stations. The Iowa Public Television name was adopted in 1982. In 2003, it purchased KQCT-TV in Davenport, which repeated the programming of Quad Cities PBS station WQPT-TV in the Iowa side of the Quad Cities. The calls were changed to KQIN. IPTV was originally run by the state's General Services Department before Governor Terry Branstad signed a bill creating the Iowa Public Broadcasting Board on May 16, 1983. In 1986 IPTV became part of the state's Cultural Affairs Department, and on July 1, 1992, IPTV became part of the Iowa Department of Education. Combined, the nine IPTV stations reach almost all of Iowa and portions of the surrounding states of Illinois, Minnesota, Nebraska, South Dakota, Missouri, and Wisconsin. 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「Iowa Public Television」の詳細全文を読む スポンサード リンク
