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 transaction size means that the OFT was obliged to examine BSkyB’s purchase of the VMtv channels. The transaction will probably be approved because of the small impact on Sky’s share of NAR (Net Advertising Revenue), which will rise from around 14% to 16%

The more pressing competition concern, which has attracted little attention, is Sky’s growing market power in the determination of carriage fee payments. Nevertheless the lack of companies actively prepared to complain to the OFT probably means that the transaction will go through without a murmur

Separately, the likely purchase of Five by Richard Desmond raises regulatory issues to do with the possible reduction of media ‘plurality’. The Sky/VMtv transaction and Channel 4’s taking over UKTV advertising sales also places Five Sales in a significantly weaker position, but any attempts to join with one of the big three sales groups (ITV, Channel 4 or Sky) may well be rejected by the competition regulators

Subject to BBC Trust approval, Canvas looks almost certain to launch in spring 2011 after the OFT decided that it did not have the jurisdiction to review Canvas under the merger provisions of the Enterprise Act 2002. The OFT decision does not rule out complaints on other grounds, but the chances of persuading the regulators look very small

The launch of Canvas promises to strengthen significantly the free-to-air digital terrestrial platform, otherwise very limited compared with satellite and cable platforms in terms of bandwidth, but mass adoption poses numerous challenges and it is open to question whether Canvas will ever extend to more than half the DTT base

In the long term, it is hard not to see Canvas as an interim step in the growing convergence between the TV screen and the internet, raising the question of how successfully its PSB TV-centric approach can adapt to the coming challenges of the full blown digital age
