The World Wide Web

1991 CE

History · Contemporary · Holocene · Meghalayan

At CERN, a physics laboratory, Tim Berners-Lee married two existing things, the internet and hypertext, into a third: a universal space of linked documents, with an address for everything. Proposed in 1989 and announced to the world in August 1991, the web ran on three simple inventions, URLs, HTTP and HTML, and on one institutional decision that mattered as much: in 1993, CERN gave the software away, unpatented, to everyone.

Why it matters

The web moved humanity's knowledge, commerce and conversation into one shared, searchable place within a generation, the largest change in how information reaches people since printing. Its inventor's own worry completes the fiche: the founding principles, universality, decentralization, open access, are not laws of nature but choices, defended or lost one decision at a time. The lineage from clay tablet to hyperlink runs through this timeline; this is its latest chapter.

Dating & uncertainty

Tim Berners-Lee proposed the system at CERN in March 1989, ran the first site by the end of 1990, and announced the project publicly in August 1991, the anchor used here. In April 1993, CERN put the software into the public domain, the renunciation that let the web belong to everyone.
