What is HyperText and HyperMedia?




Hypertext is a text which contains links to other texts. The term was invented by Ted Nelson around 1965. Hypertext is usually non-Linear.

Hypertext is Non-liner documents by clicking on hot spots in the text. The reader is immediately transported to related material in the document. Content table like views – such as the one at the left are provided. Navigation in the document is by hot spots of “overview” mechanisms.

HyperMedia is not constrained to be text-based. It can include other media, e.g., graphics, images and especially the continuous media – sound and video. Apparently, Ted Nelson was also the first to use this term.


The World Wide Web (WWW) is the best example of hypermedia applications.
