We have revised our 2019 TV advertising forecasts down to -5% year-on-year due to the prospect of Brexit on 31 October, without an agreement and transition period of continued free trade to the next trading regime with the EU, thus implying the interruption of the free flow of goods across the UK's borders with Ireland, France and the EU generally.

With the UK economy already grinding to a standstill, forward guidance for Q3 2019 indicates further decline, and the prospect of a hard Brexit will make advertisers even less willing to commit TV budgets in November and December. As a result we forecast TV advertising to be down 6.7% in H2 2019.

Understandably, no official and reliable economic forecast for no-deal Brexit is in the public domain, so we are not yet in a position to forecast TV advertising revenue for next year.

In China, Alibaba and Tencent compete for food delivery to expand access to a fast-growing source of mobile user data, using their chat and wallet super apps to funnel customers to their food delivery apps

In the West, the rivalry is direct between the food delivery apps – Just Eat, Uber Eats, and Deliveroo – and the costs of last-mile delivery dissuade challengers

In the UK, Amazon will change the game if it succeeds in its proposed purchase of a minority stake in Deliveroo, which Uber failed to buy last year. Progress on the merger of Amazon and Deliveroo is suspended by the regulator

Google’s advertising business has begun losing market share in the US, with competition from Amazon, Facebook and Microsoft intensifying in search and display

In response, the company is redoubling efforts to reshape its apps, services, and the entire web for more efficient monetisation, spelling uncertainty for partners and users

The adaptability and complexity of Google’s services reduce business risk from targeted regulatory measures, but increase the pressure for a radical intervention

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

We expect total TV ad revenues to decline 3.3% in H1 2019, partly due to a return to Earth following the idyllic conditions of the World Cup in June 2018.

Bad omens for advertising for H2 include the sagging economy since April and the Government’s impetus to achieve Brexit on 31 October, with or without a deal.

Our forecast remains a 3% decline for total TV ad revenues for 2019 as a whole, with the risk of a more serious downturn in 2020 in the wake of Brexit.

Video sharing platforms, like YouTube, Facebook Watch and Twitch, are vying to attract creators with monetisation options such as branded content and user payments.

Advertising income, already limited for many small and medium-sized creators, has been undermined by YouTube’s response to brand safety concerns.

The new tools come with their own obstacles, but are necessary to keep platforms attractive to video creators.

Online advertising plays a larger role in the UK economy than anywhere else in the world, having grown hand-in-hand with the highest ecommerce spend per capita and a business creation boom.

There are many factors behind this success, access to investment and top talent (both technical and creative) structural characteristics in the economy and society—not least a culture of experimentation and entrepreneurship.

As with all maturing industries, sustaining future growth will bring new challenges: along with economic headwinds, UK online advertising now faces an urgent need to restore public trust, with a combination of statute and self-regulation.

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

After the most challenging period in its history since 2012, Facebook has been able to stabilise its fundamental metrics and announce a major product overhaul

Despite talk of a business model pivot, Facebook’s focus remains on advertising, whose growth will remain concentrated in developed markets

News publishers wishing to stay relevant on the upgraded product set need to target exclusive layers of social interaction, with groups particularly important

The commercial challenges for media online are well-documented: online advertising pays for utilities such as search and social networking many times over, but not for media beyond user-generated content and low-investment journalism.

There are also costs from a user perspective: wasted time, harmful content created to attract views, and the collection, sale, use and frequent leakage to criminals of personal data.

Different sectors have found varying success with alternatives: games, video and music are attracting user payments, driving the paid online economy up 15.5% to £8.2 billion in 2018.
