However, it is quite debatable if the Sega Saturn, or any console prior to the original PlayStation, had much to contribute for this since they had all done poorly in the market.
Well the PS1 was the most popular CD thing for its time, but by the time it was released we were all quite familiar with CDROM. Manhole on the Mac...when was that? Late 80s. Then TG-16, which was playing CD-G demos in the Toys R Us stores. Then the Sega CD which on one hand was a huge flop, but f*cking anyone who knew anything about games was familiar with it. You could rent it almost anyplace that had games, and it sold a shitlaod of units, honestly. Then CD-i which ran late night infomercials ("Interact, Dave") for years. Windows 95, and Performa Macs from that time also brought CDROM into the computing mainstream. The 3DO, as shitty as it is, was a well known machine. Then you had the Jag CD, the Amiga CD32, Playdia, PC FX, the Saturn (only about a month before the PS in Japan, I think) and God knows what else.
By the time the Playstation was released CDROM was fully entrenched.
