Young people are spending more time playing and socialising online than watching television programmes, according to an annual survey tracking children's media behaviour in the UK.
Among those watching TV, the Netflix on-demand service was more popular than any conventional television channel.
There was also a surge in children's ownership of tablet computers, up by 50% compared with last year.
The annual media monitoring report, based on a sample of more than 2,000 five to 16-year-olds, has been following children's viewing behaviour since the mid-1990s.
This year's findings from Childwise are being claimed as a tipping point with children switching from conventional television to spending time online.
'The average time spent online is now three hours per day, compared with 2.1 hours watching television'.
