Twin Cities PBS
Twin Cities PBS (abbreviated TPT, from the name Twin Cities Public Television used on-air until 2015 and still used as the organization's legal name) is a non-profit organization based in Saint Paul, Minnesota, United States, that operates the Twin Cities' two Public Broadcasting Service (PBS) member television stations, KTCA-TV (virtual channel 2.1, UHF digital channel 34) and KTCI-TV (virtual channel 2.3, UHF digital channel 23), both licensed to Saint Paul. It produces programs for local, regional and national television broadcast, operates numerous websites, and produces rich media content for Web distribution. Twin  Cities PBS also serves the Mankato market (via K26CS-D [relaying KTCA] and K29IE-D [relaying KTCI] in nearby St. James through the local municipal-operated Cooperative TV [CTV] network of translators), as that area does not have a PBS member station of its own. History. Twin Cities Public Television was incorporated in 1955 as Twin City Area Educational Television. KTCA (channel 2) began broadcasting as the first non-commercial Public television station in the state on September 16, 1957, from a shabby, WWII wooden barracks-type structure on the University of Minnesota Agricultural Campus. The studios and offices were  moved in the 1960s to what was known as the Minnesota Statehood Centennial Memorial Building for Education Television, at 1640 Como Avenue in Saint Paul. (Incidentally, that building housed another Twin Cities commercial television station, WUCW, channel 23, from 1989 to 2018.) KTCA's first program was "Exploring Science". A second station, KTCI (channel 17), was launched on May 4, 1965. Channel 17 was originally assigned to the Tedesco Brothers in the early 1950s to be a commercial station, WCOW-TV, affiliated with the DuMont Television Network, but that station never made it to air. In 1967, KTCA became the  first educational television station in the United States to broadcast in color. In 1977 it changed its corporate name to Twin Cities Public Television. On September 15, 2000, the stations began their first digital television broadcasts, 10 years after moving to 172 4th Street East in downtown Saint Paul. In 2000, KTCA and KTCI were rebranded "tpt2" and "tpt17", paving the way for the larger family of digital broadcast services to come. In 2003, TPT became the first broadcaster in Minnesota to launch a channel, "tptHD", fully devoted to high-definition programming, and in 2005 the organization launched a full -time digital channel, "tptMN", devoted entirely to local and regional programs. In December 2005, the organization began distributing many of its productions online, making programs available through iTunes, Google Video, and Yahoo! Podcasts among others. Its website features streaming video as well as video podcasts. In 2007, TPT began offering Video-On-Demand (VOD) thorough local cable providers. KTCA's Nielsen ratings are among the highest of any PBS station in the country. During the summer of 2015, a new name and logo, "Twin Cities PBS", was introduced, before debuting on air on September 30, 2015. The rebrand included an  updated version of the tpt logo that had been used since 2000, by Minnesota design agency Capsule. Productions. TPT is one of the few public television organizations that regularly produces programs for the national PBS schedule. Major productions include: In addition, TPT has produced the children's science series: Other series included "Right on the Money". "", produced in collaboration with "Make magazine", premiered on PBS stations and the web in 2009. TPT also regularly produces programs exclusively for and about Minnesota and the surrounding region. Its Friday night public-affairs program "Almanac" has aired weekly for more than 35 years . Other significant local productions include numerous concerts with the Saint Paul Chamber Orchestra, "Minnesota: A History of the Land" (2005), "North Star: Minnesota's Black Pioneers" (2004), the series "Don't Believe The Hype" (10 seasons), "Seth Eastman: Painting the Dakota" (2001), "Death of the Dream: Farmhouses in the Heartland" (2000), the series "Tape's Rolling", "Wacipi-Powow" (1995), "Lost Twin Cities" (1995), "Dakota Exile" (1995), "The Dakota Conflict" (1993), "Iron Range: A People's History" (1994), and "How to Talk Minnesotan" (1992). The Minnesota Channel. The Minnesota Channel (TPT MN) is a full-time statewide network originating at Twin  Cities Public Television and carried on digital subchannels of nine stations. It features programming related to Minnesota and Wisconsin, including ethnic and public-affairs programming. In 2003, TPT began setting aside time on KTCI for the "Minnesota Channel", an evening dedicated to local and regional related programming, which expanded to a full-time digital subchannel on September 16, 2005. The Minnesota Channel was expanded region-wide in Minnesota and North Dakota in February 2008. Digital television. Digital channels. The stations' digital signals are multiplexed: KTCA-DT and KTCI-DT began broadcasting on channels 16 and 34 on September 16, 1999 . Analog-to-digital conversion. TPT rearranged its on-air lineup on February 18, 2009. It continued to use both KTCA-DT and KTCI-DT's transmitter, but shut down the separate tpt17 service and unified all over-the-air channels as virtual subchannels of 2. TPT's stations shut down their analog signals at 9 a.m. on June 12, 2009, the date on which full-power television stations in the United States transitioned from analog to digital broadcasts by federal mandate. The station's digital channel allocations post-transition are as follows: The then-new channel lineup was originally meant  to coincide with the DTV transition. When the transition's mandatory cutoff was delayed, TPT announced the new lineup would still go forward and it would continue its analog service until the new cutoff. Until then, KTCA-TV simulcasted tpt 2 and KTCI-TV simulcasted tptLife on their analog signals. Transmission technical data. KTCA and KTCI are broadcast from the KMSP Tower in Shoreview, Minnesota.
