Reminds me of the ongoing discussions around the use and abuse of alcohol, which are also in the news this week ( "12-year-old Scotch may be the greatest alcohol, but 12-year-old Brits are the greatest alcoholics" ). The contribution by public health professionals - and the some industry players - to the debate has been to promote 'responsible use' - AND to articulate what that means, i.e. guides on how many units a day are acceptable, etc.
- Suggestion: Perhaps the BBC - which aims to not simply be a public broadcaster, but a public good - could work with researchers (such as Dr Sigmund?) to develop guidelines for parents (and others) on how many minutes/ hours a day of 'screen time' would be acceptable as part of a balanced media diet.
