Parents today are less likely to say that the internet has been a good thing for their children than they were in 2004. However, this does not mean there was a corresponding increase in the amount of parents who think the internet has been harmful to their children. Instead, the biggest increase has been in the amount of parents who do not think the internet has had an effect on their children one way or the other. Fully, 87% of parents of teenagers are online — at least 17% more than average adults.
Parents check up on and regulate their teens’ media use, not just in terms of the internet, but with television and video games as well. However, those rules lean slightly more towards the content of the media rather than the time spent with the media device.
