Sir Tim Berners-Lee (born 1955) invented the World Wide Web at CERN in 1989–91, specifying HTTP, HTML and the URL and writing the first browser and server himself. CERN placed the technology in the public domain in 1993, which is the single decision that made the web universal rather than one of several competing hypertext systems.

Steps
The problem as it stood
CERN had many incompatible systems and a constantly changing population of researchers, and documents were scattered across them. Hypertext systems existed but were self-contained: links worked inside one system and not between machines.
What he actually did
Berners-Lee combined three pieces: a global addressing scheme (the URL), a simple retrieval protocol (HTTP), and a markup format (HTML), and implemented a browser and server to prove it. Crucially, links were allowed to break — a link needs no cooperation from its target.
How it worked
Earlier hypertext systems maintained link integrity, which requires a central registry and therefore cannot scale globally. Berners-Lee accepted broken links as the price of allowing anyone to link to anything without permission. That single tolerance is what made the web grow without coordination.
What it made possible
The delivery surface everything eventually moved onto, including this corpus's subject. Video went from a broadcast medium to a web resource, and the browser became the universal client — which is why streaming ultimately displaced broadcast delivery.
What happened to him
He founded the W3C, was knighted, received the Turing Award, and has campaigned on web decentralisation and personal data ownership, arguing the web has become too concentrated.
Where the credit landed
Berners-Lee is properly credited and unusually clear about what he did not do — the internet was already there, and hypertext long predates him. The decision that mattered most may have been institutional rather than technical: CERN releasing the specifications royalty-free in 1993, the same move that made the compact cassette and MIDI universal, and the opposite of what happened with MP3 patents.
Pro Tips
- Allowing links to break is what let the web scale without central coordination.
- CERN put it in the public domain in 1993 — that is why the web won.
- The internet already existed; the web is an application on top of it.
Knowledge Base
What You'll Learn
The web won by requiring less of everyone than its rivals did.
Why royalty-free keeps winning
This corpus contains the experiment run several times. The compact cassette was licensed free and became universal. MIDI was royalty-free and is still in use forty years later. The web was released into the public domain and displaced every proprietary rival. MP3 was patent-encumbered and was eventually superseded, and Chiariglione left MPEG arguing licensing dysfunction was threatening newer standards. The pattern is consistent enough to be worth stating as a rule.
Where This Fits
This guide covers one specific part of the history of media technology. The wider picture — how each link in the chain from capture through transmission to display was actually built, who built it, and why the credit so often landed somewhere else — is in A History of Broadcast Technology: The Chain From Capture to Screen, which frames the discipline as a whole and links out to the detailed guides underneath it, including this one. If you are starting from scratch rather than solving a specific problem, read that first and come back here.
FAQ
Q: What exactly did Tim Berners-Lee invent?
A: The World Wide Web: the URL addressing scheme, the HTTP protocol, the HTML format, and the first browser and server. The internet that carries it already existed.
Q: Why did the web beat other hypertext systems?
A: It required nothing of the people being linked to — links could break, so no central registry was needed — and CERN released the specifications royalty-free in 1993.
