The Public Service Broadcasters (PSBs) are in the process of sliding from TV dominance to middling contenders, in terms of content expenditure and significance to viewers

There are calls from many sides that the PSBs need to collaborate in order to thrive, in an era when global debt-funded SVOD services are making all the running

This note explores what can realistically be achieved by PSB collaboration; where partnerships work best; and the areas best avoided

Linear TV is ageing, and the largest channels are ageing fastest. There is an ongoing double-whammy effect of a growing older population, and the loss of younger viewers to social media and SVOD services.

The PSBs are suffering more than most, especially the BBC channels. 31% of the population is aged 55+, but over 60% of viewing to BBC1 and BBC2 is by those aged 55+.

The trend can be halted, and even reversed to some degree. There is no inevitability to this ageing process, but it will take concerted efforts to fight it.

Despite significant changes in people’s video viewing habits over the last few years, the TV platform landscape has appeared to have reached an equilibrium.

We expect pay-TV to retain its utility status for most existing customers. At the margins, movement from Sky and Virgin Media to free-to-air or pay-lite services will be mitigated by population growth.

The excitable growth phases for Netflix and Amazon are likely to be over, but they have carved out prominent positions in the market. Meanwhile, the uncomplicated allure of free TV remains strong for half the UK.

The TV, the main screen in the house, is rapidly becoming connected to the internet, opening a new front in the battle for people's attention

Tech players, pay-TV operators, and manufacturers are all aiming to control the user interface, ad delivery and data collection, leaving incumbent broadcaster interests less well represented

To protect their position, and the principles of public service broadcasting, broadcasters will have to work with each other at home and in Europe to leverage their content and social importance

The market for addressable TV looks constrained despite its benefits, with Sky AdSmart taking less than 2% of overall TV ad revenues. Meanwhile, online video revenues for Google, Facebook and others have surged dramatically

Agencies are seemingly enraptured by online video – a highly profitable medium to buy – despite concerns about a lack of effectiveness, safety and transparency 

For broadcasters to compete, better radical collaborative action is needed, including industry-wide adoption of AdSmart, and overhauling the trading agreements which hinder its take-up
