For review and discussion, a SONY Factory Tour: Televisions, Transistor Radios, Cameras, Trinitron Tube, Tape Recorders, Electronics Products of the 1950's and 1960's. History documentary shows many women factory workers, assembly lines, building, testing, quality testing in an original SONY Corporation promotional film. How may this differ from today's Japanese factories? What is your view? Many vintage SONY electronics products are shown, including first SONY tape recorder, SONY TR 55 Transistor Radio, First Transistorized Television (TV-8) and more. Good narration. Great color! Sony, Tokyo, Japan. For Historical review and comment, your comments are welcome!.
