"Hypertext is text which contains links to other texts. The term was coined by Ted Nelson around 1963 (but an article using the term was published term in 1965).
The prefix hyper- (comes from the Greek prefix "υπερ-" and means "over" or "beyond") signifies the overcoming of the old 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. — Nelson, Literary Machines, 1992”
