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.
