Hypertext
Non-sequential text connected by user-navigable links—Ted Nelson's 1960s implementation of Bush's associative trails—that became the structural foundation of the World Wide Web and established linking as fundamental to digital knowledge.
Ted Nelson coined 'hypertext' in 1963 to describe text that branches and allows reader choice—a direct implementation of Bush's associative trails concept. Nelson's Xanadu project attempted to build a universal hypertext system where every document could link to any other, where links were bidirectional and visible, and where authors would be compensated when their work was referenced. Xanadu was never completed, but the concept shaped the World Wide Web's architecture. Tim Berners-Lee's 1989 hypertext system—HTTP, HTML, URLs—realized Bush's vision of global associative navigation while simplifying Nelson's complex vision into a form that could scale. Hypertext established that documents need not be consumed linearly, that readers could follow their own paths through knowledge, and that the network of links was as important as the linked content.

Hypertext transformed reading from consumption to navigation. In print culture, the author controlled sequence—the reader proceeded from page one to page N, encountering material in the order the author determined. Hypertext transferred
