On this day 21 years ago Tim Berners-Lee (now Sir Tim Berners-Lee) announced in the Internet group comp.sys.next.announce the creation of the World Wide Web, at that time a browser that would revolutionize the world as we know:

“The WorldWideWeb application is available as an alpha version in binary and source from info.cern.ch.
WorldWideWeb is a browser / editor hypertext allows a person to read information from remote servers and local files. Create hypertext links and browse them, and also create indexes for questioning by remote lists useful documents.”

Thus began that legendary post still available through Google Groups and indeed the page you referenced in this post is still active (though as a tribute to the original page, not the content).

Congratulations, World Wide Web.
It’s the 21st birthday of World Wide Web.
