In 1994, Bill Gates famously demonstrated the potential of digital storage by holding up a compact disc and remarking, “This CD-ROM can hold more information than all the paper that’s here below me.” The moment symbolized the coming shift from physical to digital information.

Gates’ statement reflected Microsoft’s growing focus on multimedia and digital innovation during the 1990s. As the internet and personal computing expanded, his prediction proved accurate—data storage and distribution would soon move from paper and discs to vast digital networks and cloud systems.
