The first website put online 25 years ago

On December 20, 1990, Tim Berners-Lee activated the first ever website after developing a navigator at the European Nuclear Research Center in Switzerland.

The very first website was put online on December 20, 1990 by Tim Berners-Lee. At the time, the engineer is a researcher at CERN (European Center for Nuclear Research) in Switzerland. The site,, is hosted on a NeXT computer of the research center. The source code of the embryo of HTTP is published in parallel by Tim Berners-Lee, as well as the first browser (WorldWideWeb) that he developed with the help of a center engineer, Robert Cailliau. The site gathers documentation on the project, and information to create its own site.

Tim Berners-Lee’s server technology then extends to other research centers across Europe and the world. In November 1992, there were 26  web servers and 200 in October 1993.

Manage scientific information

Originally, Tim Berners-Lee developed this technology, which he called Mesh, to manage the large amounts of scientific information manipulated within CERN. It is conceptualized a year and a half ago by the engineer. Its goal is to find a method to allow researchers to navigate, but also to collaborate via co-publication spaces.

First website published on (this is a reconstitution visible on the W3C website at this address – the original site no longer exists).

More than 900 million websites today

In April 1993, version 1.0 of the first graphical Internet browser was published by the National Center for Supercomputing Applications (NCSA) at the University of Illinois in the United States. It’s Mosaic . It will be renamed in 1994 Netscape. Starting in 2004, Firefox will rely on its latest generation kernel.

Appointed a researcher at the Massachusetts Institute of Technology (MIT) in 1994, Tim Berners-Lee founded the World Wide Web Consortium ( W3C ) the same year. The organization brings together private and public research stakeholders ready to engage in the standardization of web technologies and the improvement of their quality, with a view to the generalization and promotion of the network. Tim Berners-Lee is ennobled by Elisabeth II in 2004 for his role in the development of the Internet.
