BARB data indicates that the amount of average daily TV set viewing to linear TV channels is continuing to fall: the pie is shrinking. Just under 20% of TV set usage so far in 2017 is to non-linear activity, and viewing to SVOD services and YouTube is likely to account for most of this growth in 'unmatched' viewing
The pie is shrinking faster amongst younger audiences: just under one third of TV set usage is 'unmatched' now for 16-34s. However 35+ unmatched use is growing at a faster rate than 16-34 unmatched use in 2017
Within this smaller pie, the PSB channels continue to hold share of viewing against pay channels. Within the PSBs, ITV and the ITV digital channel family have gained most share so far this year, although BBC1 is having a strong autumn in spite of the loss of Great British Bake Off to C4
