A Timeline of the Internet & Computing
From Turing's paper machine to the AI boom — how computing ate the world, with sources.
Ninety years from a mathematical thought experiment to a networked planet: the machines, protocols, and products that built the digital age. Sourced to the Computer History Museum, Nobel Prize records, CERN, W3C, university archives, and primary documents.
Events
- November 1936Peer-reviewed · 2 sourcesWell documented
Turing defines the universal machine
Alan Turing's paper "On Computable Numbers" described an abstract machine that could compute anything computable — a blueprint for every computer since.
Why it matters: Computing began as an idea: one machine, given the right instructions, can do any calculation.

ENIAC, the first general-purpose electronic computer
Unveiled at the University of Pennsylvania, ENIAC filled a room with 18,000 vacuum tubes and computed a thousand times faster than any machine before it.
Why it matters: Proof that electronic, programmable computation worked at scale — the industry starts here.

The transistor is invented at Bell Labs
Bardeen, Brattain, and Shockley demonstrated the first transistor — a solid-state switch that would replace the vacuum tube.
Why it matters: The most manufactured device in human history; every chip is billions of its descendants.
Sources - September 1958General sourceWell documented
The integrated circuit
Jack Kilby at Texas Instruments demonstrated the first working integrated circuit; Robert Noyce independently developed a practical version months later.
Why it matters: Putting a whole circuit on one chip made Moore's Law — and everything after it — possible.

ARPANET sends its first message
UCLA student Charley Kline tried to send "LOGIN" to Stanford; the network crashed after "LO" — the first message on the ARPANET, the internet's direct ancestor.
Why it matters: Two computers talking over a packet-switched network: the internet's opening syllable.
Sources - 1971General sourceWell documented
Email crosses between machines
Ray Tomlinson sent the first network email on ARPANET, choosing the @ symbol to separate user from host.
Why it matters: The internet's first killer app — and the @ convention the world still types daily.

Intel 4004: the microprocessor
Intel released the 4004, the first commercial computer-on-a-chip, built for a Japanese calculator.
Why it matters: A CPU you could hold — the component that made personal computers inevitable.
Sources - January 1, 1983General sourceWell documented
The internet switches to TCP/IP
ARPANET's "flag day" migration to the TCP/IP protocol suite let independent networks interconnect as one internet.
Why it matters: The common language of the internet — still the protocol under every connection today.
Sources - January 1984General sourceWell documented
The Macintosh mainstreams the GUI
Apple's Macintosh brought the graphical interface — windows, icons, mouse — to a mass-market machine.
Why it matters: Computers stopped being command lines for specialists and became tools anyone could point at.

Tim Berners-Lee proposes the Web
At CERN, Berners-Lee wrote "Information Management: A Proposal" — hypertext documents linked across the internet. His boss's note: "Vague, but exciting."
Why it matters: The memo that became the World Wide Web.

- August 1991Unverified sourceWell documented
The Web goes public
Berners-Lee posted the World Wide Web project to public newsgroups, releasing the first website, browser, and server to the world.
Why it matters: The moment the Web left the lab — from one server at CERN to a billion-plus sites.
Sources - August 1991General sourceWell documented
Linus Torvalds announces Linux
A Finnish student posted about his hobby OS kernel — "just a hobby, won't be big and professional."
Why it matters: Linux now runs most servers, every Android phone, and the majority of the cloud — open source's flagship.
Sources - April 1993General sourceWell documented
Mosaic makes the Web visual
NCSA's Mosaic browser displayed images inline with text and installed easily — Web traffic exploded within months.
Why it matters: The browser that turned the Web from a text tool for researchers into a medium for everyone.

Google is founded
Larry Page and Sergey Brin incorporated Google, ranking pages by the link structure of the Web itself.
Why it matters: Organizing the Web's information became one of the most consequential businesses in history.

Wikipedia launches
A free encyclopedia anyone could edit sounded absurd — it became the largest reference work ever assembled.
Why it matters: Proof that open, volunteer collaboration could build knowledge infrastructure at planetary scale.

The iPhone
Steve Jobs introduced a phone, an iPod, and an internet communicator — one device. The multi-touch smartphone defined the next two decades.
Why it matters: It moved the internet into billions of pockets and made mobile the default computer.
Sources - October 31, 2008Primary sourceWell documented
The Bitcoin whitepaper
The pseudonymous Satoshi Nakamoto published "Bitcoin: A Peer-to-Peer Electronic Cash System" — digital money without a central authority.
Why it matters: Whatever one thinks of crypto, the blockchain idea reshaped finance, regulation, and computing debates.

ChatGPT ignites the AI boom
OpenAI released ChatGPT as a free research preview; it reached an estimated 100 million users in two months — the fastest-adopted consumer application to that point.
Why it matters: Generative AI went from research demo to daily tool for hundreds of millions, resetting the industry's direction.
