scan of the original proposal


In March 1989, Tim Berners-Lee, along with Robert Cailliau, at CERN, the European Organization for Nuclear Research, circulated "Information Management: A Proposal."

It imagined a simple client-server architecture, and links, and a 6 month time frame.

His boss at CERN at the time — Mark Sendall — labeled it the now classic understatement of the century: "Vague, but exciting."


In November 1990, the proposal was re-formulated.

At the same time, Tim Berners-Lee, working on a NeXT computer, completed the earliest version of an application he called WorldWideWeb. This program is the antecedent of most of what we consider or know of as "the web" today.

The WorldWideWeb application was considered a prototype or test of a networked "HyperMedia Browser/Editor." WorldWideWeb was the user-facing layer. This browser/editor application worked on a local machine on local files. However, in conjunction with this application, Tim also developed the first hypertext server software known as "httpd" which ran in the background and was the server to which the browser would connect to serve up, what we know today, as "web pages."

The naming of the project was fairly contentious, and many debates took place with "The MESH", The Information Mine, and simply "the Web" as major contenders. WorldWideWeb was later renamed Nexus to avoid confusion with the World Wide Web project. It was originally developed in Objective C, using Interface Builder on a NeXT computer. NeXT computer was founded by Apple founder Steve Jobs after his ouster from Apple, but only sold a few tens-of-thousands of devices.

To make the Web more widely accessible (because almost nobody had a NeXT machine), a second browser project was developed at CERN: the Line Mode browser. The Line Mode browser was first released in 1991 and was compatible with most unix / linux systems. Thereby instantly bring the Web to commonly used, much lower powered devices, such as the "line mode" terminals that were used to access mini computers, still common at the time.


In February 2019, in celebration of the thirtieth anniversary of the development of WorldWideWeb, a group of developers and designers convened at CERN to rebuild the original browser within a contemporary browser, allowing users around the world to experience the origins of this transformative technology.

Philosophy of the Web

While the Web is largely thought of as a medium for consuming information, the WorldWideWeb browser also allowed the user to edit and create web pages. This reflects the philosophy of the Web as both read and write medium, well captured in this observation by Tim Berners-Lee "If you think surfing hypertext is cool, that's because you haven't tried writing it".

Key phrases:

www-talk, the World Wide Web Mailing list

On the 28th October 1991. Tim Berners-Lee started the World Wide Web mailing list, which has in one form or another run ever since, though it's rarely posted to today.

It documents many of the innovations of the Web over the last 28 years.

Some notable, or interesting conversations include:

Abbreviated lineage of web servers and browsers, post-1990

Three main technologies were developed essentially in tandem around 1990: the WorldWideWeb NeXT hypertext browser, the CERN httpd web server, and the libwww C library. Most of the modern web is descendant from this trio. Here's a basic time line of how the propagation occurred:
