Compact Disc, 1980

Electronics giants Sony and Phillips joined forces to design a digital audio disc as a spin-off from those cumbersome and expensive Laserdiscs. The CD was commercially available in 1982. As costs of development for CD's and CD players became lower it became the primary format for music. Although MP3's are quickly replacing CDs as the primary media for music today, CD technology is still used in CD-ROMs, DVDs, and Blu Ray. I can't imagine physically rewinding or fast forwarding anything anymore
