Original prompt & settings (JSON) ↗The first proposal never called the invention the “World Wide Web” — Berners-Lee's working name was “Mesh” — and his manager's entire famous verdict was three handwritten words.
March 1989: “Vague but exciting”
During March 1989, CERN computer scientist Tim Berners-Lee wrote and circulated “Information Management: A Proposal” to address information loss in CERN's large, rapidly changing collaborations. His manager Mike Sendall annotated it “Vague but exciting.”
The 14-page document derived a solution based on distributed hypertext: information nodes and links that could cross existing databases and computer systems.
What the document actually asked for
Berners-Lee required remote network access, support for heterogeneous computers, access to existing data, and the ability to join systems without central coordination. He estimated that two people working six to twelve months could complete the first phase, and treated a 24-by-80-character text screen as sufficient in the short term.
The text did not yet use “World Wide Web” as the system's name; Berners-Lee says his working name was “Mesh.” Nor did it specify HTML, HTTP and URLs in their implemented forms, which were developed later.
The anniversary date is not on the document
12 March is the conventional anniversary used for Web celebrations, but it is not independently established by the proposal, which is dated only “March 1989.” CERN's archive records it as 1989-03 with no day, and CERN's own timeline explicitly says no exact date is given; the surviving document does not establish that Sendall's annotation was made on 12 March either.
No working Web, browser, server, HTTP protocol or HTML language was launched that day. What existed was a written proposal for a decentralized, portable hypertext system circulating within CERN, with implementation following in 1990.

Date disputed. Sources disagree; the research places it at ~1989-03.
What the sources leave uncertain
- The surviving proposal is dated only “March 1989,” and CERN’s archive records it as 1989-03 with no day. CERN’s own timeline explicitly says no exact date is given.
- 12 March is the conventional anniversary used for Web celebrations, but it is not independently established by the document. The best-supported date is therefore approximately March 1989.
- The surviving text was redistributed in May 1990 with a second date added but otherwise unchanged, which has caused occasional confusion over when the original was written.
