In 1952, educators and broadcasters met in State College, Pa., to discuss the potential of a new technology—television—for education. The mood was hopeful yet tempered with skepticism. One attendee pessimistically compared the medium with the potential of “atomic energy”; perhaps neutral, but possibly dangerous.

One of the special guests of this conference was a slight man, with horn-rimmed glasses and wisps of white hair. He suggested, optimistically, that television was actually the perfect tool for education. “The potential is there, the professional enthusiasm exists, and the medium can be the instrument of swift advance toward lasting values,” he argued.
