Turbo GrafX-16 and PC Engine CD add on could play CDs in 1990. Every disc-based CD add on or system prior to PS1 could play CDs so that wasn't exactly new. I got my first Boom box in 1995 and it had a CD player. First Discman in 96. We are not wealthy by any means but my dad got a stereo for the house in 1992 and it had a 5 disc changer. I still listened to cassettes as well as they were often cheaper but we had a few CD players. All my friends family had at least 1 CD player.
