CD ROMs, which are computer disk drives for computers, were first made in the year 1985. Writable or recordable CDs came later, in 1988. These, with the help of CD recording devices, let users make their own CDs, which they could then play on CD players. On a not so promising note, CD players are fast losing out on popularity, thanks to new digital innovations like the MP3 player.
