During its development, MCA, which owned the technology, referred to it as the Reflective Optical Videodisc System; changing the name once in 1969 to Disco-Vision and then again in 1978 to DiscoVision (without the hyphen), which became the official spelling. MCA owned the rights to the largest catalog of films in the world during this time, and they manufactured and distributed the Discovision releases of those films under the "MCA DiscoVision" label beginning on December 15, 1978.

Pioneer Electronics also entered the optical disc market in 1978, manufacturing players and printing discs under the name Laser Videodisc. For 1980 the name was compressed into LaserDisc and in 1981 the intercap was eliminated and "Laserdisc" became the final and common name for the format, supplanting the use of the "DiscoVision" name, which disappeared shortly thereafter; titles released by MCA became MCA Laserdiscs or (later) MCA-Universal Laserdiscs. The format has been incorrectly referred to as LV or LaserVision, although this actually refers to a line of Philips brand players; the term VDP or Video Disc Player was a somewhat more common and more correct name for players in general.

During the early years, MCA also manufactured discs for other companies including Paramount, Disney and Warner Bros. Some of them added their own names to the disc jacket to signify that the movie was not owned by MCA. When MCA merged into Universal years later, Universal began reissuing many of the early DiscoVision titles as MCA-Universal discs. The DiscoVision versions had largely been available only in pan and scan and had often utilized poor transfers, the newer versions improved greatly in terms of both audio and video quality.

History

Laserdisc technology, using a transparent disc, was invented by David Paul Gregg in 1958 (and patented in 1961 and 1969). By 1969 Philips had developed a videodisc in reflective mode, which has great advantages over the transparent mode. MCA and Philips decided to join their efforts. They first publicly demonstrated the videodisc in 1972. LD was first available on the market, in Atlanta, on December 15, 1978, two years after the VHS VCR and four years before the CD, which is based on laserdisc technology. Philips produced the players and MCA the discs. The Philips/MCA cooperation was not successful, and discontinued after a few years. Several of the scientists responsible for the early research (Richard Wilkinson, Ray Deakin, and John Winslow) founded Optical Disc Corporation (now ODC Nimbus), and that company is still the world leader in optical disc mastering technology.
