Compact disc
Compact disc (CD) is a digital optical disc data storage format that was co-developed by Philips and Sony and released in 1982. The format was originally developed to store and play only sound recordings (CD-DA) but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. The first commercially available audio CD player, the Sony CDP-101, was released October 1982 in Japan.
De Wolfe Music
Digital technology bought changes to the music industry in the 1980's, particularly with the evolution of CDs. In 1985 de Wolfe launched its DWCD collection of 6 CDs, becoming the world's first digital production music library. De Wolfe ultimately ended the production of its vinyl series in 1988, and the end of the production of CDs would come in 2014 as de Wolfe shifted focus to online delivery.
