History of the Compact Disc

A Compact Disc (also known as a CD) is an optical disc used to store digital data, originally developed for storing digital audio. The CD has been available on the market since October 1982, and remains the standard physical medium for sale of commercial audio recordings to the present day. The technology was later adapted and expanded to include data storage CD-ROM, and this was followed by write-once audio and data storage CD-R and rewritable media CD-RW. Other variants were developed including: Video Compact Discs (VCD), Photo CD, and Enhanced CD.
