In early 1990 at CERN headquarters in Geneva, Switzerland, Tim Berners-Lee and Robert Cailliau published a formal proposal to build a “Hypertext project” called “WorldWideWeb” as a “web” of “hypertext documents” to be viewed by “browsers”.

Following development work the pair introduced the proposal to a wider audience in December, and on August 6, 1991, 20 years ago, the World Wide Web officially opened for business on the internet. On that day Berners-Lee posted the first web page — a short summary of the World Wide Web project on the alt.hypertext newsgroup.

The page authored by Tim Berners-Lee was http://info.cern.ch/hypertext/WWW/TheProject.html. A later version on the page can be found here. The page described Berners-Lee’s summary of a project for organizing information on a computer network using a web or links. In fact, the the effort was originally coined “Mesh”, but later became the “World Wide Web”.

The first photograph on the web was uploaded by Berners-Lee in 1992, an image of the CERN house band Les Horribles Cernettes. Twenty years on, one website alone — Flickr – hosts around 5.75 billion images.
