In 1990, a symposium at the convention of the American Psychological Association developed the definition of TV addiction as "heavy television watching that is subjectively experienced as being to some extent involuntary, displacing more productive activities, and difficult to stop or curtail."

Though not considered an "official" mental disorder, there is a growing body of evidence that pieces together the framework of the TV addict.

Television, has however, been linked to autism. In a study contradicting the widespread belief that the presence of mercury and other heavy metals in childhood vaccines contributes to autism, Cornell University researchers demonstrate what appears to be a causal relationship between television viewing by young children and a growing incidence of the disorder.

The U.S. Department of Labor reported in September 2004 that watching TV accounted for about half the leisure time on average for both American men and women. The Department's Time Use Survey showed that watching TV was third in total daily use of time behind working and sleeping.

Watching television is culturally approved use of one's time. Using the above statistics, the average American will spend about 3 hours per day watching television which adds up to 15 hours a week. If a person spends about 9 hours sleeping, then at least one day's entire waking hours each week are spent watching TV.

There is no doubt that television exerts a strong grip on the watcher. However, is a high amount of TV watching due to cultural norms combined with a genuine interest in what is broadcast or is the watcher simply powerless to turn it off? What are the factors that can mutate this devotion to television into a harmful addiction?

Is television addictive? Most psychological research suggests that TV can certainly become addictive and that heavy TV watchers display all the symptoms of a non-substance behavioral addiction.

Breaking free of TV, and any addiction, is not an easy task. The difficulty in replacing television images with different (and more substantial) activities is the greatest obstacle breaking the addiction.
