By March 1991, a simple ‘Line-Mode’ browser was made available to users of CERN’s central computers. Although it had less features than the more sophisticated NeXT browser/editor, it had the big advantage of being able to run on a wider range of computers. It was written by Nicola Pellow during her student work placement at CERN. A project to restore the first ever Website includes a description of the Line Mode browser.  

By Christmas 1990, Sir Berners-Lee had defined the Web’s basic concepts, the html, http and URL, and he had written the first browser/editor and server software. info.cern.ch was the address of the world's first web server, running on a NeXT computer at CERN. The world's first web page address provided information about the World Wide Web project.

In November 1990, Sir Tim Berners-Lee, together with CERN colleague, Robert Cailliau, submitted a formal management proposal for ‘WorldWideWeb: Proposal for a HyperText Project’. 

In March 1989, Sir Tim Berners-Lee, while working at CERN, wrote a proposal to develop a distributed information system. He resubmitted a slightly edited version in May 1990.
