PlayStation [SEP] Origins
PlayStation was the brainchild of Ken Kutaragi, a Sony executive who managed one of the company's hardware engineering divisions and was later dubbed "The Father of the PlayStation". The console's origins date back to 1988 where it was originally a joint project between Nintendo and Sony to create a CD-ROM for the Super Famicom. Although Nintendo denied the existence of the Sony deal as late as March 1991, Sony revealed a Super Famicom with a built-in CD-ROM drive, that incorporated Green Book technology or CD-i, called "Play Station" (also known as SNES-CD) at the Consumer Electronics Show in June 1991.
