From Telephote to Television: A Fantastic Journey

Stephen R. Wilk

Unlike the telephone, the television did not have one clear inventor. It was shaped over decades by the minds of researchers as well as science fiction writers. When it was first conceived and developed, a device that could instantaneously transmit images was referred to as a “telephote.” more>>
