The Information Commissioner’s Office reported on the UK online advertising sector, finding common industry practices unlawful under a strict interpretation of the GDPR and UK privacy law

The ICO focused on problems around transparency, consent and data sharing in the Real-Time-Bidding ecosystem, which comprises 16% of UK online ad spend, but most of publisher online ad revenue. The ICO is giving the industry six months to shape up, with the next steps still unclear

The Competition and Markets Authority has had under consideration an investigation into the entire online advertising sector, but is hampered by Brexit-related considerations

UK online advertising spend continued its double-digit growth in 2018, up 11% to reach nearly £13bn in annual spend or 58% of the total advertising market, but a no-deal consumer downturn could nearly stop growth this year

Google, Facebook, Amazon, professional services firms and the largest marketing cloud companies are the biggest winners, while content media, media agencies and independent advertising technology firms languish 

Self-regulation has improved as pressure mounts on advertising technology firms, but interventions by both privacy and competition authorities are now inevitable

Our central case forecast with orderly EU withdrawal predicts 2.7% growth for total UK advertising spend, down from 4.7% in 2018. We have a no-deal Brexit scenario that predicts a smaller advertising recession than in 2009, with total ad spend declining 3% and display down 5.3% in 2019

The total advertising figures partly mask the pressure on UK consumers, through an expansion of the measured advertising spend universe. This is due to significant self-serve online advertising growth by SMEs, and non-advertising marketing budgets moving to online advertising platforms

In a downturn, we’d expect advertisers to become more tactical, which would disproportionally affect display media including TV, which is further affected by declining commercial impacts among younger adults. Search and social advertising would see only small growth through the first year of a recession

The decline in demand in print presents trading challenges, but the more immediate pressures are on the supply side, with a 15% rise in paper prices accentuating the burden of production and distribution costs

With digital advertising growing at stubbornly low rates, UK publishers need to return to their fundamental consumer-centred strengths by switching their strategic attention towards strong brands, curation, and community

The case for specialist, branded publishing media remains robust: products, services, and consumers are still best brought together in an authoritative, trusted media environment. Advertisers and agencies (and also media) have undervalued the effectiveness of those environments, and direct-to-consumer opportunities have been exaggerated by many brands

Online advertising became the majority of all UK ad spend last year, in step with China but ahead of all other major markets. 

Direct response has further increased its share to 54% of UK ad spend, fuelled by the self-serve platforms of Google, Facebook and Amazon, while content media nets just 11% of the online advertising pot.

We estimate that all online-delivered channels - including "pure play" online properties, broadcaster VOD, digital out-of-home and online radio - could account for well over 60% of UK ad spend by 2020, but only with improved commitment to industry governance.
