Have you ever heard of the Nintendo Playstation? Sounds ridiculous right? Despite what you may think, this was at one time a real thing. In 1992 Nintendo and Sony signed a deal allowing Sony to produce SNES hardware, with Nintendo retaining control of the game sales. In short, this would mean a profit gain for the actual system. However, only Nintendo would gain from the discs even though the games are processed on discs developed by Sony(kinda a low ball move on Nintendo's part if ya ask me).
The start of this deal started back in 1988 when a Sony engineer began showing interest in video game development while watching his daughter play the Nintendo Famicom. He took on a contract at Sony for developing hardware that would drive the audio subsystem of Nintendo's next console, the Super NES. Kutaragi secretly developed the chip known as the "Sony SPC 700". As Sony was uninterested in the video game business, most of his superiors did not approve of the project. Nevertheless, Kutaragi found support in the form of Sony executive Norio Ohga, and the project was allowed to continue. The project's success spurred Nintendo to enter into a partnership with Sony to develop both a CD-ROM add-on for the Super NES and a Sony-branded console that would play both SNES cartridges, as well as titles released for the new Super Disc format.
During development, Sony and Nintendo fell short on the terms of their business agreement. Apparently, momma didn't raise no fool! Despite the partnership with Sony; Nintendo secretly sighned a partnership with Philips who was Sony's leading competitor in the market at the time. As described by David Sheff in his book Game Over, “[The Philips deal] was meant to do two things at once: give Nintendo back its stranglehold on software and gracefully fuck Sony."At the June 1991 Consumer Electronics Show, Sony announced its SNES-compatible cartridge/CD console, the "PlayStation". The next day, Nintendo revealed its partnership with Philips at the show—a surprise to the entire audience, including Sony.
While Nintendo and Sony attempted to sort out their differences, between two and three hundred prototypes of the PlayStation were created, and software for the system was being developed. The two organizations never repaired the rift between them and by the next year, Sony had dropped further development of the Super NES CD-ROM said Fuck you Nintendo, and instead refocused its efforts on developing its own console for the next generation of consoles which became known as the PlayStation. After the original contract with Sony failed, Nintendo continued its partnership with Philips. This contract provisioned Philips with the right to feature Nintendo's characters in a few games for its CD-i multimedia device, but never resulted in a CD-ROM add-on for the SNES. The Nintendo-themed CD-i games were very poorly received, and the CD-i itself is considered a commercial failure.
