CERN, the European Organization for Nuclear Research, is where it all began in March 1989. A physicist, Tim Berners-Lee, wrote a proposal for information management showing how information could be transferred easily over the Internet by using hypertext, the now familiar point-and-click system of navigating through information. The following year, Robert Cailliau, a systems engineer, joined in and soon became its number one advocate.

The idea was to connect hypertext with the Internet and personal computers, thereby having a single information network to help CERN physicists share all the computer-stored information at the laboratory. Hypertext would enable users to browse easily between texts on web pages using links. The first examples were developed on NeXT computers.
