Concern is spreading over children's excessive media use such as Internet, violent video games, and online gambling and pornography. Today's young people grow up in a media-saturated culture.

Ask any 10 or 12 year old about this issue and they will probably not understand why anyone would consider it a problem. After all, today’s kids don’t know any life without an abundance of electronic devices. Electronic stimuli are simply part of the world they were born into.

While there is much concern about the potential damage of all this, there has not been sufficient research in the past. But new vast quantities of research are emerging. We are now learning the risks (and the occasional benefits) of what is going on.
