According to Phillips and Sony, who jointly introduced the audio CD format, the CD was first marketed in November 1982 in Japan and in March 1983 in Europe. I remember picking up a Sony CD player in the Akihabara district in Tokyo in 1984, because I happened to be there on business and I knew the latest and greatest models were only in Japan at that time.
Would love to see one of the 1970’s models from Kenjit’s collection...
