Sony Playstation 1

General PS1 information
The PS1 was released in 1994, 1995, and 1996. The Japanese version was released in 1994, the North American version was released in 1995, the European version was released in 1995, the Australian version was released in 1995, and the Korean version was finally released in 1996. In 2000, the PS1 was rereleased as a smaller model in 2000. The Playstation was actually originally the SNES-CD, or the Play Station. It was a deal by Nintendo and Sony. But, the deal ended. So, Sony developed the rest of the console by theirselves. The PS1's competitors were the Nintendo 64 and the Sega Saturn (Note: The articles for it's competitors have not been created yet).

SNES-CD (aka the Play Station)
As said in the first part of this article, the SNES-CD was the early Play Station. It was a deal by Nintendo and Sony, but the deal ended, so Sony developed the PS1 by theirselves. Actually, the SNES-CD was just nicknamed the Play Station. It was just an add-on to the SNES. Apparently, it was going to be a fourth generation console. Also, there are actually over 200 SNES-CD/Play Station prototypes.
