CD-ROM developed by Japanese company Denon in 1982. It was an extension of Compact Disc Digital Audio, and adapted the format to hold any form of digital data, with a storage capacity of 553 MiB. CD-ROM was then introduced by Denon and Sony at a Japanese computer show in 1984. The "Yellow Book" is the technical standard that defines the format of CD-ROMs. One of a set of color-bound books that contain the technical specifications for all CD formats, the "Yellow Book", standardized by Sony and Philips in 1983, specifies a format for discs with a maximum capacity of 650 MiB.
