Kind of a weird title. The SNES CD was the Playstation ancestor. The CD-i was a device made independently that Nintendo partnered with after they dumped Sony.
Spurned by Nintendo, Sony took their SNES CD tech and created the Playstation from it.
Nintendo did more than just dump Sony, they humiliated them.
Originally, Sony was supposed to be Nintendo's partner for the CD-i machine. Nintendo went behind Sony's back and partnered with Phillips.
At the summer 1991 CES when Sony was expecting the CD-i machine and their partnership with Nintendo to be announced, Nintendo announced the product with Phillips as their partner.
I can't help but wonder how much animosity towards Nintendo contributed towards the development of the Playstation 1.
I remember thinking at the time that the PS1 controller was just like a Snes controller with extended hand grips. They just changed the out the colours / letters for shapes.
It only beat Sega CD to the market by less than two weeks. Which, to be fair, wasn't a standalone console, it needed to attach to a Genesis, however they did sell combined (CD plus Genesis) consoles.
