A proposal

At CERN in March 1989, Tim Berners-Lee proposed the World Wide Web to help scientists share information.

Different milestones

He and Robert Cailliau formalised the proposal in November 1990. By the end of that year, a server and browser were working at CERN. A proposal, a working system and wider availability are distinct milestones.

Claims and evidence

The first proposal dates to March 1989; a server and browser were running by the end of 1990.
