The World Wide Web
Linking documents changes who can publish
Tim Berners-Lee circulated a proposal for linked information at CERN in March 1989, addressing practical difficulties in sharing knowledge across a changing research community.
The proposal and implementation were separate milestones. W3C's historical record places the proposal in March 1989 and demonstrable software at Christmas 1990. The internet, hypertext research, and earlier networking practices supplied foundations. The achievement was a workable integration that others could adopt, not the solitary invention of digital communication.
By the end of 1990, a browser-editor and server made the project demonstrable, with Robert Cailliau and other colleagues contributing to its development.
The World Wide Web used an already developing internet; it did not invent the underlying network or the earlier idea of linked electronic text.
Its combination of addresses, document formats, and communication rules let information held on different computers become accessible through a relatively consistent browsing experience.
A reader could follow references immediately, and a publisher could connect a small page to a much larger field of documents and audiences.
A link changes the cost of moving between sources, not the quality of every source it connects. Readers gained routes around established publishers, while new intermediaries learned to organize those routes. Publication became easier without making attention equally available. This is why technical openness and the distribution of public influence must be assessed separately.
CERN's 1993 decision to allow free use helped wider adoption, alongside improved browsers, expanding connectivity, and the work of many independent developers.
For ordinary users, websites gradually changed shopping, correspondence, study, and contact with institutions, although convenience arrived unevenly across languages, incomes, and places.
New publishing opportunities did not eliminate gatekeepers; search services, hosting companies, and later platforms acquired influence over what became visible or economically sustainable.
The web also made copying and misleading presentation easier, increasing the importance of source evaluation without making every old authority automatically trustworthy.
Its promise remains partly institutional: interoperable tools can widen participation, but openness requires maintenance, accessibility, and rules that prevent concentrated control from becoming unavoidable.
