Yesterday, April 30th 2013, was the 20th anniversary of the public release of the World Wide Web. Although the first website was launched two years earlier in 1991, it was on this date 20 years ago that CERN made the WWW technology available royalty-free. To commemorate the date, CERN has put a 1992 copy of the site up at the original URL: https://info.cern.ch/hypertext/WWW/TheProject.html
