Context
During the Cold War, the US military needed a communications network that could survive a nuclear strike. Traditional centralized networks had a fatal flaw: destroy the hub, and the entire system collapses. Researchers at RAND, MIT, and the UK's National Physical Laboratory independently developed the concept of distributed, packet-switched networks.
The Deed
On October 29, 1969, the first ARPANET message was sent from UCLA to Stanford. The system crashed after transmitting just two letters: 'L' and 'O' of the word 'LOGIN.' Over the next two decades, researchers developed the protocols that would become the internet: TCP/IP (Cerf and Kahn, 1974), DNS (1983), and finally the World Wide Web (Berners-Lee, 1989). Berners-Lee created HTTP, HTML, and the first web browser at CERN, then made the technology freely available to all.
Why It Matters
The internet is arguably the most transformative technology since the printing press. It rewired commerce, politics, education, entertainment, and human relationships. It enabled the rise of the information economy and put the sum of human knowledge at everyone's fingertips.
Brutal Truth
The internet has also enabled mass surveillance, disinformation at scale, cybercrime, and digital addiction. Social media platforms have been linked to rising anxiety and depression, especially among young people. The open, idealistic internet of the early years has given way to one dominated by a handful of corporations.
By the Numbers
- 5.3 billion internet users worldwide (2024)
- First message sent: October 29, 1969
- Tim Berners-Lee made the Web free, forgoing billions in potential revenue
- Over 1.1 billion websites exist today
