Videodisc

Video disc is a general term for a laser-readable random-access circular disc that contains both audio and video forms of multimedia. Typically, it is a reference to any such media that predates the mainstream popularity of the DVD format. Such formats include:

• MCA DiscoVision (1978)
• Pioneer LaserDisc (1980)
• RCA Selectavision (1981)

Unlike the battles between VHS and Beta, there was no serious format war between early video disc formats as the LaserDisc proved to be technologically superior to all challengers of its time. The modern DVD format prevailed with only a slight interest to its challenger format, DIVX.
