hypertext
hypermedia

   <hypertext> A term coined by Ted Nelson around 1965 for a
   collection of documents (or "nodes") containing
   cross-references or "links" which, with the aid of an
   interactive {browser} program, allow the reader to move easily
   from one document to another.

   The extension of hypertext to include other media - {sound},
   {graphics}, and {video} - has been termed "{hypermedia}", but
   is usually just called "hypertext", especially since the
   advent of the {World-Wide Web} and {HTML}.
