  <title>The Idea of Hypertext</title>
   <b>HTML</b> stands for HyperText Markup Language.  Hypertext expresses the idea
   that you can click on what you are reading to jump to something else
   which is related.  This is the same <i>hyper</i> in hyperspace 
   that the characters in your favorite
   science-fiction story are always jumping through.  The idea is to
   go immediately to a distant place.  In the case of documents,
   you are going to
   a place which may be far away in whatever scheme is normally used
   order the documents.
   HTML is a way of expressing hypertext, but the idea
   is older.  The first mention 
   is probably
   Vannevar Bush's description of Memex
   in 1945.  The term was coined by Ted Nelson in 1965, and was
   popularly embodied in the HyperCard application shipped with the
   original Apple Macintosh 
   (see <tt>http://www.fact-index.com/h/hy/hypertext.html</tt>).
