The "X" in the original call sign WPSX-TV denotes that the station was an extension of Penn State. "The establishment of the station," said Dr. Eric Walker, then-president of the university, "will enable Penn State to expand its educational services". WPSX-TV was led by Marlow Froke, director of the Division of Broadcasting at Penn State, as a unit of Continuing Education. On March 1, 1965, under his leadership in cooperation with the newly-formed Allegheny Educational Broadcast Council (AEBC) advisory board, WPSX-TV broadcast to 124 elementary and secondary schools across Pennsylvania to supplement the curriculum and provide in-service training for teachers. The first day's lineup included Saludos Amigos, Primary Concepts in Math, Focus on Fitness, and 12 other programs between 10 a.m. and 3 p.m. Froke, a former journalism instructor and radio-television newsman, said in a 1965 Altoona Mirror interview, "Television can combine all the channels of communication—sight, sound, and motion—to give the greatest impact on the student". During the first WPSX-TV broadcast school year, the classroom TV service reached approximately 250,000 students in 22 counties. Evening programs of culture, public affairs, and adult education were added on June 7, 1965, in a Monday-to-Friday, 7–11 p.m. schedule. Saturday and Sunday programming was not added until nearly two years later. Once the microwave link that carried the broadcast signal to Wagner was completed, WPSX-TV began moving its broadcast and studio operations to its new facility. On December 10, 1965, engineering, production, and programming staff were all based at the Wagner studios for the first time and remained there until a new digital broadcast facility was dedicated on September 8, 2005, as the Outreach Building in Innovation Park. WPSX-TV drew upon Penn State's faculty and staff to develop original programming for the new evening lineup. Art History 10, which was hosted by assistant professor of art history Carl Barnes and covered painting, architecture, and sculpture, was the first University credit course to be produced for broadcast in late 1965. Public affairs programs covered national, state, and University issues. In 1969, P. J. O'Connell produced The Year Behind, the Year Ahead, reporting on the events that led to the student sit-in protest on Old Main Lawn. O'Connell and co-producer Kimberlie Kranich went on the create the Rural American Documentary Project (later renamed Pennsylvania Parade) with more than 150 titles that captured the life, joys, and struggles of rural Pennsylvanians, including Notes on an Appalachia
