VCD

Before the advent of DVD and Blu-ray, the Video CD (abbreviated as VCD, and also known as View CD, Compact Disc digital video) became the first format for distributing films on standard 120 mm optical discs. The format is a standard digital format for storing video on a Compact Disc. VCDs are playable in dedicated VCD players, most DVD-Video players, personal computers, and some video game consoles.

The VCD standard was created in 1993 by Sony, Philips, Matsushita, and JVC and is referred to as the White Book standard. Though supplanted by the two aforementioned formats, VCDs are still popular, particularly in the low cost market.
