WPTD, UHF digital channel 16, is a PBS member television station located in Dayton, Ohio, United States. The station's signal is relayed by W32DS-D in Maplewood, Ohio. WPTD's digital transmitter is located off South Gettysburg Avenue in the Highview Hills neighborhood in southwest Dayton. WPTD has a sister station, WPTO, virtual channel 14 (UHF digital channel 28), also a PBS member. Licensed to Oxford, WPTO provides a second choice for PBS programming in Cincinnati alongside that city's flagship PBS station, WCET. WPTO's transmitter is located in the South Fairmount neighborhood on the northwest side of Cincinnati (and is shared with Cincinnati's Fox affiliate, WXIX-TV, channel 19). Together, the two stations are known on-air as the ThinkTV Network. WPTD brands as "ThinkTV16", while WPTO brands as "ThinkTV14". Despite shared branding, WPTO does not operate as a satellite of WPTD. The two stations are separately programmed and scheduled. While the two stations share some programs, there is virtually no overlap except during pledge drives. ThinkTV operates as a subsidiary of Public Media Connect, a regional non-profit company that also owns WCET. Master control operations for all three stations are based at ThinkTV's facilities on South Jefferson Street in Dayton. WPTD's broadcast coverage includes much of southwestern Ohio, including Dayton and Cincinnati, as well as portions of eastern Indiana. WPTO's smaller coverage area largely overlaps that of WPTD, but is more concentrated in the extreme southwest corner of Ohio, providing a stronger signal to Cincinnati, and a weaker rimshot signal to the Dayton area. Both stations are available on Time Warner Cable throughout southwestern Ohio, though some providers may offer only WPTD's set of digital subchannels or WPTO's, depending on their location. ==History== WPTD first signed on the air on April 24, 1972 as WOET-TV (standing for "Ohio Educational Television"); it was operated by the Ohio Educational Broadcasting Network Commission (OEB). Prior to the station's launch, the channel 16 frequency in Dayton was occupied by a commercial independent and sometime ABC-affiliated station, WKTR-TV.〔http://img384.imageshack.us/i/wktrgames1970gw5.jpg〕 That station was owned by Kitty Hawk Television Corporation and licensed to Kettering when it began broadcasting in April 1967. It went dark February 27, 1971, but returned to the air with a limited schedule from April until October while the license transfer to OEB was pending Federal Communications Commission approval. The FCC formally reallocated the frequency as non-commercial September 14, 1977. WPTO began broadcasting on October 14, 1959 as WMUB-TV, operated by Miami University. The call letters matched those of then co-owned WMUB radio, and stood for "Miami University Broadcasting". It was the secondary educational station in the Cincinnati area, alongside future sister WCET. The two stations joined forces in 1975 under the banner of University Regional Broadcasting, a consortium of Miami, Wright State and Central State universities. WMUB-TV served as the primary station for a year, until WOET-TV became the primary station in 1976. In 1977, the stations were transferred to a new community organization, Greater Dayton Public Television, and received their current callsigns, with WOET-TV becoming WPTD and WMUB-TV becoming WPTO. From the creation of University Regional Broadcasting onward, the secondary station operated as a semi-satellite of the primary station, only rarely airing different, usually local public affairs-type, programs. This situation existed until cable television began to become widely available in Cincinnati and Dayton. As cable availability rose, Greater Dayton Public Television began to differentiate its stations' programming gradually, with the stations eventually becoming separately programmed. The stations rebranded themselves as the ThinkTV Network in 1998, though the legal name remained Greater Dayton Public Television. On October 31, 2008, Greater Dayton Public Television and the Greater Cincinnati Television Educational Foundation, owner of WCET, announced plans to merge their resources into one non-profit organization serving all of Southwest Ohio, while maintaining separate identities. The merger completed on May 8, 2009 with the formation of Public Media Connect, Inc. Both ThinkTV and CET operate as subsidiaries under the new organization. The merger resulted in the July 2010 transfer of WCET's master control operations to ThinkTV's facilities in Dayton.〔 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「WPTD」の詳細全文を読む スポンサード リンク
