The word hypertext was invented in 1965

The term hypertext was invented in 1965 by Ted Nelson to designate a set of interconnected digital documents that cannot be presented in a linear manner on paper. This foundational notion was accompanied by his Xanadu project, a global system intended to centralize all world literature with a micropayment system for copyright. This large-scale project, described in his work Computer Lib/Dream machines published in 1974, nevertheless remained at the prototype stage.
