Title: Video
Content: replaced by cathode ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Video was originally exclusively a live technology. Charles Ginsburg led an Ampex research team developing one of the first practical video tape recorder (VTR). In 1951 the first video tape recorder captured live images from television cameras by converting the camera's electrical impulses and saving the information onto magnetic video tape. Video recorders were sold for US $50,000 in 1956, and videotapes cost US $300 per one-hour reel. However, prices gradually dropped over the years; in 1971, Sony began selling

Title: Videocassette recorder
Content: the history of videotape recording in general. In 1953, Dr. Norikazu Sawazaki developed a prototype helical scan video tape recorder. Ampex introduced the Quadruplex videotape professional broadcast standard format with its Ampex VRX-1000 in 1956. It became the world's first commercially successful videotape recorder using two-inch (5.1 cm) wide tape. Due to its high price of , the Ampex VRX-1000 could be afforded only by the television networks and the largest individual stations. In 1959, Toshiba introduced a "new" method of recording known as helical scan, releasing the first commercial helical scan video tape recorder that year. It was first

Title: Video tape recorder
Content: and demonstrated on June 24, 1963, was the first home video recorder. It could be bought as a unit or in kit form for £60. However, there were several drawbacks: it was expensive, not easy to put together, and can record for only 20 minutes at a time in black-and-white. The Sony model CV-2000, first marketed in 1965, is their first VTR intended for home use and is based on half-inch tape. Ampex and RCA followed in 1965 with their own open-reel monochrome VTRs priced under US $1,000 for the home consumer market. Prerecorded videos for home replay became available

Title: Video tape recorder
Content: recorders. Agreement by Japanese manufacturers on a common standard recording format, so cassettes recorded on one manufacturer's machine would play on another's, made a consumer market possible, and the first consumer videocassette recorder was introduced by Sony in 1971. In early 1951 Bing Crosby asked his Chief Engineer John T. (Jack) Mullin if television could be recorded on tape as was the case for audio. Mullin said that he thought that it could be done. Bing asked Ampex to build one and also set up a laboratory for Mullin in Bing Crosby Enterprises (BCE) to build one. In 1951 it

Title: Erhard Kietz
Content: was mainly achieved through the emerging transistor technology and, only a little later, through integrated circuits with rapidly growing complexity. When one sees the current video recording devices, one cannot even imagine anymore how much signal processing is necessary for video recording and play-back. The first video recorders were housed in several cabinets full of electronics. Television video recording was practically a fall-out of the military application. From the end of the 1960s on into the 1980s, Ampex video tape recorders were utilized in television studios all over the world. During his tenure at Ampex Corporation, Dr. Erhard Kietz developed
