BARB figures show drop in younger TV viewers
The BBC and Channel 4 have lost a significant proportion of their younger TV audience over the last three years, according to new BARB figures seen by the i newspaper.
The data reveals that between 2010 and 2013, the TV viewing of the BBC's portfolio of channels by young people, aged between 25 and 34, fell 12% - 5% higher than the market average decline of 7%.
Channel 4's 16-24 year old demographic suffered the most, losing 19% of television viewers, while Sky lost 18% and ITV 13% in the same category.
However, the figures do not include mobile and tablet viewing and could be indicative of an online migration by younger audiences.
Despite losing almost a fifth of its younger viewers, earlier this year Channel 4's database of unique registered users surpassed the 10 million mark - including one in two of all 16-24 year olds in the UK.
Similarly, in March the BBC announced that it will be moving its flagship youth channel, BBC Three, wholly online as the Corporation looks to both make cost savings and to follow younger audiences to new platforms.
Commenting on the BARB figures, a Channel 4 spokesperson said: "Over 2014 our share of young 16-34 viewers is up one per cent year on year - with our young-skewing channel E4 enjoying a record start to the year, up five per cent.
"C4 continues to have a unique appeal with a young audience. In the last three years more than half of the UK's 16-24 year olds have registered with us as part of our viewer engagement strategy."
A statement from the BBC said: "The BBC is committed to all audiences and while across our portfolio we have the highest share of young viewers - and iPlayer is the UK's leading on-demand service - we are working hard to ensure we keep innovating in this area.".
