Hypertext

Documents that are connected by hyperlinks.
Engineer Vannevar Bush wrote "As We May Think" in 1945 in which he described the Memex, a theoretical proto-hypertext device which in turn helped inspire the subsequent invention of hypertext.
Douglas Engelbart in 2009, at the 40th anniversary celebrations of "The Mother of All Demos" in San Francisco, a 90-minute 1968 presentation of the NLS computer system which was a combination of hardware and software that demonstrated many hypertext ideas.

Hypertext is text displayed on a computer display or other electronic devices with references (hyperlinks) to other text that the reader can immediately access, or where text can be revealed progressively at multiple levels of detail (also called StretchText).[1] Hypertext documents are interconnected by hyperlinks, which are typically activated by a mouse click, keypress set or by touching the screen. Apart from text, the term "hypertext" is also sometimes used to describe tables, images, and other presentational content formats with integrated hyperlinks. Hypertext is one of the key underlying concepts of the World Wide Web,[2] where Web pages are often written in the Hypertext Markup Language (HTML). As implemented on the Web, hypertext enables the easy-to-use publication of information over the Internet.

Etymology

'Hypertext' is a recent coinage. 'Hyper-' is used in the mathematical sense of extension and generality (as in 'hyperspace,' 'hypercube') rather than the medical sense of 'excessive' ('hyperactivity'). There is no implication about size— a hypertext could contain only 500 words or so. 'Hyper-' refers to structure and not size.

— Theodor H. Nelson, Brief Words on the Hypertext, 23 January 1967

The English prefix hyper- comes from the Greek prefix "ὑπερ-" and means "over" or "beyond"; it has a common origin with the prefix "super-" which comes from Latin. It signifies the overcoming of the previous linear constraints of written text.

The term "hypertext" is often used where the term "hypermedia" might seem appropriate. In 1992, author Ted Nelson – who coined both terms in 1963 – wrote:

By now the word "hypertext" has become generally accepted for branching and responding text, but the corresponding word "hypermedia", meaning complexes of branching and responding graphics, movies and sound – as well as text – is much less used. Instead they use the strange term "interactive multimedia": this is four syllables longer, and does not express the idea of extending hypertext.
