Hypertext is defined as text that has links in it.  When you activate
a link, you are taken to a new page relating to that link.

Multi-Media is defined as the combination of text with other elements
such as sound, graphics, and video.

Hypertext and multimedia can be combined.  The WWW encourages this
combination of these two features.  Such a combination is referred to
as 'hyper-media.'

There are still some under-represented areas on the Internet.  The
net is currently still the most populated by people with technical
skills and a relatively high educational background.  The people who
are capable of building Web pages today tend to have technical
interests.  You might not find local issues at the level of your
neighborhood yet.  Certain issues and occupations have few advocates
on the Web as yet.  These might include any field not normally
associated with technology.  

\ans
Any topic that you can imagine probably has at least one page.
Certain topics have IMMENSE volumes of information available on the
Web.  These topics are the ones that many people with Web development
skills are interested in.  Most Web authors are still in school, so
you will find many pages about school issues (at every level from
elementary to post - graduate.)  The military and educational
representation on the web is very strong, as you would guess by
reading this chapter.  People love to make pages about their hobbies.
You will find a page about any hobby you can imagine.  You can also
find lots of information about pop culture.  Most musical groups,
movies, models, and TV shows have official and unofficial home pages.
