At the National Association of Broadcasters (NAB) convention in Chicago, Ampex demonstrates the first commercially-available videotape deck, the Ampex VRX-1000 Quad VTR, using two-inch-wide open-reel videotape, in spools with a 14-inch diameter, to record and play back up to an hour of television programming. Over the next four days, Ampex receives orders from broadcasters totaling over two million dollars. CBS will give the VRX-1000 its first national on-air use in November, tape-delaying a newscast to its stations on the west coast, allowing the first broadcast of a single program at the same hour in different time zones. NBC will also have the VRX-1000 in use at the beginning of 1957. A newer model capable of recording and playing back programming in full color will become available in 1958. Though it does not record at the same resolution as film, the relative ease of use of videotape will see it replace kinescope film in most TV operations.
