Charles Ginsburg led the research team at Ampex Corporation in developing the first practical videotape recorder (VTR). In 1951, the first video tape recorder (VTR) captured live images from television cameras by converting the information into electrical impulses and saving the information onto magnetic tape. Ampex sold the first VTR for $50,000 in 1956. The first VCassetteR or VCR was sold by Sony in 1971.
