The real story
Tim Berners-Lee built the World Wide Web at CERN in Switzerland. The first site, info.cern.ch, went public in 1991, served from a NeXT computer. Stuck on the front was a label: 'This machine is a server. DO NOT POWER IT DOWN!!' Turning it off would have switched off the entire web.
In 1993 CERN made the web's software free for anyone to use, with no patents and no fees. That decision is why the web exploded. The original page was lost over the years, so in 2013 CERN restored it at its original address. You can still visit it today.
