World Wide Web opens

Tim Berners-Lee proposed a linked-information system at CERN in 1989; he and collaborators built a browser/editor, server, URLs, HTTP and HTML, and the first public website appeared in 1991. CERN's 30 April 1993 release put core Web software in the public domain.

Why it matters

The Web used the older internet rather than inventing it. Open standards encouraged global publishing and research, while browsers, networks, institutions and users shaped later commerce, participation, surveillance, platform concentration and unequal access.

The Web is not the internet

The internet's packet-switched networks and protocols existed before the Web. Berners-Lee's proposal joined hypertext to internet addressing and transfer through URLs, HTTP and HTML, while the first browser was also an editor. This distinction keeps network infrastructure separate from a service built on it.

CERN: The birth of the Web ↗

Opening happened in stages

The proposal dates to 1989, the first server and browser to 1990 and the first public website to 1991. On 30 April 1993 CERN released core Web software into the public domain, enabling implementation without royalties. Browsers, standards groups, servers and publishers then drove adoption beyond one inventor or laboratory.

Openness did not guarantee equality

The Web lowered some barriers to publishing and linking while access still depended on networks, devices, literacy, language and policy. Later search engines and platforms concentrated attention, data and advertising power. Those outcomes were shaped by business and governance choices, not contained inevitably in the 1989 proposal.
