History

The first conceptions of the PlayStation date back to 1986. Nintendo had been attempting to work with disc technology since the Famicom, but the medium had problems. Its rewritable magnetic nature could be easily erased (thus leading to a lack of durability), and the discs were a copyright infringement danger. Consequently, when details of CDROM/XA (an extension of the CD-ROM format that combines compressed audio, visual and computer data, allowing all to be accessed simultaneously) came out, Nintendo was interested. CD-ROM/XA was being simultaneously developed by Sony and Philips. Nintendo approached Sony to develop a CD-ROM add-on, tentatively titled the "SNES-CD". A contract was signed, and work began. Nintendo's choice of Sony was due to a prior dealing: Ken Kutaragi, the person who would later be dubbed "The Father of PlayStation", was the individual who had sold Nintendo on using the Sony SPC-700 processor for use as the eight-channel ADPCM sound synthesis set in the Super Famicom/SNES console through an impressive demonstration of the processor's capabilities.

Sony also planned to develop another, Nintendo compatible, Sony-branded console, but one which would be more of a home entertainment system playing both Super Nintendo cartridges and a new CD format which Sony would design. This was also to be the format used in SNES-CD discs, giving a large degree of control to Sony despite Nintendo's leading position in the video gaming market.

After the collapse of the joint project, Sony considered halting their research, but ultimately the company decided to use what they had developed so far and make it into a complete, stand alone console. As a result, Nintendo filed a lawsuit claiming breach of contract and attempted, in U.S. federal court, to obtain an injunction against the release of the PlayStation, on the grounds that Nintendo owned the name. The federal judge presiding over the case denied the injunction and, in October 1991, the first incarnation of the new Sony PlayStation was revealed. However, it is theorized that only 200 or so of these machines were ever produced.
