The amount and distribution by time of day of TV viewing, as well as the PSB group viewing shares have remained notably stable over the last ten years in which the major shift from analogue to digital transmissions has occurred and timeshift/catch-up viewing has become commonplace.

The topline trends nevertheless mask significant age-related under-currents of change, which have seen a large loss of younger audiences and sharply ageing profiles for BBC1, BBC2 and ITV.

Whilst the more youth-oriented Channel 4 has avoided the ageing profile effect, it faces its own challenge of averting audience decline, as it finds itself at the sharp end of change among younger adults and faces declining support among older viewers.

The development of the Digital Britain infrastructure, introduction of tablets, increasing connectivity of TV sets and launch of on demand OTT services over the internet have greatly intensified interest in connected viewing and its impact on the traditional broadcast model No single source of audience measurement for viewing of long- and short- form video content across all screens yet exists, though current market data suggest that connected viewing occupies a c. 8.5% share of total viewing across all screens By 2020, we project the connected viewing share of total viewing across all screens will reach 20%, with tablets being the primary drivers of growth, in part incremental and in part substitutional to viewing to the TV set, where we expect the connected viewing share to remain under 5%

The final Ofcom statement on the future of PSB advocates fixing the commercial PSB crisis by designating Channel 4 as the core alternative provider of public service programming to the BBC, and freeing up ITV and Five commercially by means of considerably lightened PSB obligations

The fundamental issue of the Channel 4 (or any other) solution is funding the new commercial PSB model. Eyes are now being set on a Channel 4 partnership with BBC Worldwide, centred on its UK assets as the marriage made in heaven

Another major recommendation of the Ofcom PSB proposal is the abolition of the national Channel 3 breakfast time licence, currently held by GMTV, which is running a viable business with its own sales force. This recommendation appears at odds with Ofcom’s commitment to plurality in news provision and its statutory duties to encourage competition in the communications industries
