On August 17, 1982, at a Philips factory in Langenhagen, Germany, the physical world of consumer media took its first definitive leap into the digital domain with the pressing of the world’s first commercial Compact Disc: ABBA’s *The Visitors*. Born from a landmark collaboration between rivals Philips and Sony, the CD replaced the fragile analog grooves of vinyl with microscopic pits read by a precise semiconductor laser.
The 12-centimeter polycarbonate disc did far more than deliver uncompressed, crystal-clear 16-bit audio to audiophiles; it established the standard for optical data storage. Within a decade, the CD-ROM transformed personal computing, liberating software and multimedia from the severe constraints of floppy disks. That shimmering, iridescent surface proved that zero-and-one binary code would become the universal medium for all human culture.
