DiscoVision was the original name of the “Reflective Optical Videodisc System” format later known as LaserVision or LaserDisc. MCA DiscoVision Inc. was a division of entertainment giant MCA, established in 1969 to develop and sell an optical videodisc system. MCA released discs under the DiscoVision brand from 1978 to 1982, including titles from Universal Studios, Warner Bros. Pictures, Paramount, Avco Embassy, WGBH Boston and Disney. Most of these companies later established their own labels for the format.
In 1981 they put together this wonderful promo with Mr. Spock himself, Leonard Nimoy.
