Videocassette recorder
The history of the videocassette recorder follows the history of videotape recording in general. Ampex introduced the Ampex VRX-1000, the first commercially successful videotape recorder, in 1956. It used the 2" Quadruplex format, using two-inch (5.1 cm) tape.[1] Due to its US$ 50,000 price, the Ampex VRX-1000 could be afforded only by the television networks and the largest individual stations.[2] In 1963, Philips introduced their EL3400 1" helical scan recorder (aimed at the business and domestic user) and Sony marketed the PV-100, their first reel-to-reel VTR intended for business, medical, airline, and educational use.[3] The Sony model CV-2000, first marketed in 1965, was intended for home use.[4] Ampex and RCA followed in 1965 with their own reel-to-reel monochrome VTRs priced under US$1,000 for the home consumer market.
