Learn about ourEditorial Process Updated on April 19, 2017 Charles Ginsburg led the research team at Ampex Corporation in developing one of the first practical videotape recorders or VTRs in 1951. It captured live images from television cameras by converting the information into electrical impulses and saving the information on magnetic tape.
