Broadcast radio has maintained its reach and listening time over the past decade: younger people listen less than before, but this is made up for by an ageing population.

The challenges to radio come from changes in distribution technology in the home and in cars, and from product innovation in the online audio space.

Over the next few years, we predict continued stability in radio, but as technology brings it into closer competition with online audio, broadcasters will have to continue product innovation.

The UK TV advertising market, in decline since mid-2016, could benefit from a liberalisation of advertising minutage if Ofcom reviews COSTA and decides to make changes

Broadcasters could gain from the flexibility to devote up to 20% of peaktime minutes to advertising under the EU’s revised Audiovisual Media Services Directive (AVMSD)

Ofcom could also level the playing field between PSB and non-PSB channels, although more minutes of advertising on TV is unlikely to inverse the medium’s decline

The UK government is now consulting on a wider TV advertising ban until 9pm for food and drink high in fat, salt and sugar (HFSS), to combat childhood obesity

TV and TV advertising are not the cause of children being overweight or obese (O+O). Policy change in this area should inform and educate parents and young children, as they have in Leeds and Amsterdam

With 64% of the UK population being O+O, obesity is a complex societal issue requiring a multifaceted approach. The evidence from existing rules, and plummeting TV viewing amongst children, says that further restrictions on TV advertising will be ineffective in curbing the rise of obesity in the UK

Addressable linear TV advertising, where precision-targeted ads overlay default linear ads, could enhance the TV proposition for advertisers, agencies and viewers, benefiting all broadcasters

In the context of dwindling linear viewing and rocketing online video ad spends, the adoption of Sky AdSmart and similar services on YouView and Freeview could take addressable TV ads from a sideshow to a pillar of revenue

Addressable linear is a bigger and more strategic prize for broadcasters than BVOD ads. Sky holds the key to wider adoption of its AdSmart platform if it can find a way – or a price – to bring ITV Sales and/or 4 Sales on board
