The 2006 book Future Hype: The Myths of Technology Change by Bob Seidensticker is a fascinating read. From page 103:
Schools have had a longstanding immunity against the introduction of new technologies. In 1922 Thomas Edison predicted that movies would replace textbooks. In 1945 one forecaster imagined radios as common as blackboards in classrooms. In the 1960s, B.F. Skinner predicted that teaching machines and programmed instruction would double the amount of information students could learn in a given time. Filmstrips and other audiovisual aids were fads thirty years ago, and the television, now seen as a supplier of brain candy, once had a sterling reputation as an education machine.
