For the second year running, 2014 has seen a steep year-on-year decline in total daily average viewing time, which fell by almost 5%, and was again, as in 2013, greatest among younger age demos, especially among children aged 4-15 where the decline reached double figures

Connectivity and the rapidly growing population of smartphones and tablets appear the main, though not the only, causes of a decline that appears general across the main PSB, PSB family and non-PSB channel groups. The decline nevertheless varies by channel genre, with the more youth oriented, such as Children and Music, feeling the connectivity squeeze the most

Whilst the great majority of non-PSB channels are only available on the pay-TV platforms, the DTT platform provides a significant audience and advertising contribution (ballpark estimate of £150-200 million per annum) to the relatively small group of leading free-to-air non-PSB channels, which are also less constrained in developing their online initiatives than the mixed advertising/subscription non-PSB channels on the pay-TV platforms
