In 1989, PCs were still a novelty for many folks, and at that point, how many people outside of scientific circles had every heard of something called the Internet? Things were about to start changing, though.
On March 13 of that year, a fellow named Tim Berners-Lee (seen here in 1994) working at CERN, the European Organization for Nuclear Research, made a proposal that rather drily addressed "the problems of loss of information about complex evolving systems" and proposed "a solution based on a distributed hypertext system."
What it gave birth to was the World Wide Web, and thus, eventually, Facebook, eBay, Google, iTunes, YouTube, Pets.com, blogs....
Correction: This caption originally misstated the year Berners-Lee got the Next Cube that became the first Web server. It was September 1990.
The world's first-ever Web site? Info.cern.ch
Speaking with ZDNet UK earlier this week, at a House of Lords event focused on the Internet and privacy, Berners-Lee offered this historical reflection: "When people built the Internet, it was designed to be a cloud," he said. "When routing packets, the system only looks at the envelope--it's an important design principle. Now people find out what you write in your letters."
