Spending hours watching TV or playing computer games each day does not harm young children's social development, say experts.
The Medical Research Council (MRC) team who studied more than 11,000 primary school pupils says it is wrong to link bad behaviour to TV viewing.
Although researchers found a small correlation between the two, they say other influences, such as parenting styles, most probably explain the link.
But they still say "limit screen time".
This cautionary advice is because spending lots of time in front of the TV every day might reduce how much time a child spends doing other important activities such as playing with friends and doing homework, they say.

There’s a clear link between early drinking and a higher lifetime risk of alcoholism, with each earlier year of drinking resulting in greater risk: 47% of people who started drinking at age 14 became alcohol dependent later in life, while only 9% of those who began drinking after age 21 became dependent.
Studies suggest that two factors may be at work. On the one hand, early drinking is often an indicator of an underlying propensity to alcoholism. In other words, people who are genetically or otherwise predisposed to alcoholism — or show traits, like impulsivity, that can contribute to alcoholism — are more likely to want to start drinking sooner than later. This makes intuitive sense.
But it may be that the act of early drinking itself could raise the risk of alcoholism even in people who have no family history of alcoholism or are in other ways no likelier than the later drinkers to become alcoholics. This line of research suggests that the early identification of problem drinking in young people — and the willingness to label it as a problem — may be critical to forestalling alcoholism in later
