Video recorders were developed during the 1950s by the American Ampex Corporation, which was led by Charles Ginsberg (b 1920) and Ray Dolby (b 1933). However, it was not until the late 1970s that the price of video recorders dropped, and they became more popular. The Sony videocorder was one of the first affordable videotape recorders. The original CV (Consumer Video) 2000 model was introduced in the late 1960s. TV programs could be taped off air using a specially modified video monitor or TV, and live action 'home movies' could also be recorded using a Sony TV camera. The CV-5100 was the only colour model in the series.
