Berners-Lee wrote 'Information Management: A Proposal,' outlining his vision for a distributed hypertext system to allow researchers to share information more effectively. This document is considered the foundational proposal for the World Wide Web. It addressed the problem of information loss at CERN as people came and went.

Berners-Lee developed the first web server, 'httpd,' and the first web browser, 'WorldWideWeb,' on a NeXT computer. The browser was also a WYSIWYG editor. He also wrote the first versions of HTML (HyperText Markup Language), HTTP (HyperText Transfer Protocol), and URLs (Uniform Resource Locators).

The world's first website was created and hosted on Berners-Lee's NeXT computer at CERN. It provided information about the World Wide Web project itself.

Berners-Lee publicly announced the World Wide Web on the alt.hypertext newsgroup, marking its official launch and opening it up to the wider internet community.

CERN made the core World Wide Web technology available on a royalty-free basis, ensuring its widespread adoption and preventing its commercial exploitation by any single entity. This decision was crucial to the Web's rapid growth.
