of the tape middle, audio is on one edge, control track is on the other) so that head to tape write speed is well in excess of the physical motion. They wrote the video vertically across the width of a tape that was wide and ran at per second. This allowed hour-long television programs to be recorded on one reel of tape. In 1956, one reel of tape cost $300; and Ampex advertised the cost of the recorder as $45,000. A version was released later, and this required a new, narrower headwheel. This vertical writing facilitated mechanical editing, once the control track was developed to display the pulse that indicates where a frame ends and the next one begins. Later, Ampex developed electronic editing. The National Academy of Television Arts and Sciences awarded Ampex its first Emmy in 1957 for this development. Ampex received a total of 12 Emmys for its technical video achievements. In 1959, Richard Nixon, then Vice President, and Nikita Khrushchev held discussions at the Moscow Trade Fair, which became known as the "Kitchen Debate" because they were mostly held in the kitchen of a suburban model house. These discussions were recorded on an Ampex color videotape recorder, and during the debate Nixon pointed this out as one of the many American technological advances. In 1967, Ampex introduced the Ampex VR-3000 portable broadcast video recorder, which revolutionized the recording of broadcast quality television in the field without the need for long cables and large support vehicles. Broadcast quality images could now be shot anywhere, including from airplanes, helicopters and boats. The Quadruplex format dominated the broadcast industry for a quarter of a century. The format was licensed to RCA for use in their "television tape recorders." Ampex's invention revolutionized the television production industry by eliminating the kinescope process of time-shifting television programs, which required the use of motion picture film. For archival purposes, the kinescope method continued to be used for some years; film was still preferred by archivists. The Ampex broadcast video tape recorder facilitated time-zone broadcast delay so that networks could air programming at the same hour in various time zones. Ampex had trademarked the name "video tape", so competitor RCA called the medium "TV tape" or "television tape". The terms eventually became genericized, and "videotape" is commonly used today. While the quadruplex recording system per se is no longer in use, the principle evolved
