A new generation addiction is quickly spreading all over the
world. Weboholism, a twentieth century disease, affects people from
different ages. They surf the net, use e-mail and speak in chat rooms.
They spend many hours on the computer, and it becomes a compulsive
habit. They cannot stop, and it affects their lives.
Ten years ago, no one thought that using computers could
become compulsive behavior that could affect the social and

physical life of computer users. This obsessional behavior has affected teenagers and college students. They
are likely to log on computers and spend long hours at different websites.
     They become addicted to computers and gradually their social and school life is affected by this situation.
They spend all free time surfing and don't concentrate on homework, so this addiction influences their grades
and success at school. Because they can find everything on the websites, they hang out there. Moreover, this
addiction to websites influences their social life.
     They spend more time in front of computers than with their friends. The relation with their friends changes.
The virtual life becomes more important than their real life. They have a new language that they speak in the
chat rooms and it causes cultural changes in society.
     Because of the change in their behavior, they begin to isolate themselves from the society and live with their
virtual friends. They share their emotions and feelings with friends who they have never met in their life.
Although they feel confident on the computer, they are not confident with real live friends they have known all
their life. It is a problem for the future. This addictive behavior is beginning to affect all the world.
