CDs were invented by Sony/Phillips in the late 1980s.
The DVD evolved from the CD. It is a high-density CD.
two high-density optical storage standards were being developed; one was the MultiMedia Compact Disc, backed by Philips and Sony, and the other was the Super Density disc, supported by Toshiba, Time Warner, Matsushita Electric, Hitachi, Mitsubishi Electric, Pioneer, Thomson, and JVC. They combined the 2 and released the dvd in May 1995.
