1. A Brief History of Hypermedia

Definition of the Hypertext:

"Information is linked and cross-referenced in many different ways and is widely available to end users" (Hooper, 1990).

"Hypertext means a database in which information (text) has been organised nonlinearly. The database consists of nodes and links between nodes" (Multisilta, 1995).

Vannever Bush's article "As We May Think" (Atlantic Monthly, 1945): There should be a tool that would enhance human memory and thinking and that allows people to retrieve information from a computer in many of the same ways in which retrieval is accomplished within human memory.

A Hypermedia Timeline

Ted Nelson: Xanadu is Ted Nelson's dream since early `60s: all the world literature in one publicly accessible global online system (analogy: you can today get a telephone link from anywhere to anywhere, so why not from any text to any other?). Every reference to a text will lead to royalties being paid automatically to the author. Includes the use of full versioning (claimed to be horrifyingly complex), "hot links" (called transclusions) and zippered texts (eg. parallel texts like for translations or annotations.). A few of ideas in Xanadu are now implemented in WWW.

Dough Englebart: Can be called as The father of the Hypertext. He invented f.ex. mouse and touch screens. He is also creator of one of the first hypermedia systems NLS/Augment.
