• History

  Two high-density optical storage formats were created in 1993. These were the MultiMedia Compact Disc (MMCD) and the Super Density (SD) disc. The Technical Working Group (made up of several computer companies) was formed to boycott both formats unless the two converged into one single standard. The warring companies soon agreed to converge and the single DVD format was created. Major electronics and computer companies soon adopted the DVD format. Movies began to be converted to DVD to replace VHS tapes. VHS was discontinued in 2006.
