What has been done to encourage children to get less addicted to technologies?

My question really is if there have been social or political issues, interesting initiatives or magazine or internet articles where it is shown that today’s technology, such as violent games or too much TV, is having a negative effect on children.

Some of the most obvious negative influences of technology include the lack of social skills, anti-social behaviour, stress, obesity and diet, lack of exercise, access to porn, etc..

- What do you think could be done to make children healthier and more intelligent?
– What has already been done to prevent children from spending their afternoon in front of the computer? Any revolutionary products?
– What could be done better?
– What are the problems or opportunities within the child market?

I could go on forever, but I’ll stop with the questions for now

Just let me know what you think about this. Thanks!
