The St. Lawrence Valley Educational Television Council, which was organized in 1958, originally produced educational television programming to be carried by local CBS affiliate WWNY-TV (channel 7). In 1971, it established a free-standing PBS station, WNPE-TV, using WWNY's original studios on Champion Hill as the commercial station had already relocated to a larger facility in Watertown. Full-time satellite WNPI-TV signed on a few weeks later. Outgrowing the Champion Hill location itself, WNPE moved to a new building in Watertown in 1978.
