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

TalkTalk hit the bottom end of its (revised) 2018/19 EBITDA guidance, an achievement given fierce price competition and the margin-dilutive effect of high speed upgrades

This is however helped by one-off Openreach price cuts, and price rises for ancillary products (voice calls and pay-TV) and out-of-contract customers that look hard to sustain

Subscriber growth slowed dramatically in Q4, and continuing this more measured approach could help the company counter multiple market pressures, and perhaps even lead to a détente in the current price wars

BT is accelerating its ‘full fibre’ rollout, likely due to a combination of a successful build to date, very promising regulatory developments, and (let’s not deny it) worrying competitor build plans

Full year results were a little weak versus consensus, with guidance a little soft as well, leading to questions of how this can be funded, particularly the roll-out acceleration from 2021/22 to cover half the country by the mid-2020s

Whatever the funding mechanism, we regard the investment as sound, with BT’s planned operational transformation also promising but potentially requiring further upfront investment

Q1 results evidenced the downturn that Virgin Media had flagged in February. Consumer cable weakened sharply to just 1% growth vs 3%+ historically, partly thanks to ‘increased promotions in response to market dynamics’

Monetising Virgin’s speed advantage is becoming more challenging. Competition is hotting up for high-speed broadband in particular, fuelled by Openreach targets for smaller players and BT’s full fibre and G.fast rollouts

The company faces two vital strategic decisions – whether to wholesale BT’s fibre products outside its footprint, and whether to allow wholesale access to its own network. The former is likely to have the most legs and offers an alternative to further Lightning extension

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

Sky made a surprisingly weak start to 2019, with revenue growth decelerating to 1.9% (the first time below 4% since the European businesses merged in 2015), due to weaker ARPU trends.

However, Sky expects improvement to follow, blaming one-off factors in the quarter. The ARPU weakness drove EBITDA down 11.3%, but this should bounce back across the rest of 2019 as football rights costs turn from a drag to a positive.

Comcast highlighted collaborations with Sky across tech, advertising, content distribution and even news, stating it is on track to achieve the anticipated $500 million in annual synergies over the next couple of years.

Out of Home (OOH) is bucking the trend in UK traditional media and continues to grow, driven by the digitisation of inventory as the paper estate recedes

Digital OOH now accounts for 50% of total OOH ad spend. Soon digitisation will slow, as much OOH inventory cannot be converted from posters to digital screens; sustained growth will require a different form of change

The industry is amidst structural shift – driven by consolidation and automation – which could be wholly positive, but a lack of cooperation between major players risks stifling innovation and the medium’s growth

Market revenue growth accelerated to 3% in Q4, but it might never reach this level again, being helped by a never-to-be-repeated BT overlapping price rise

With price rises becoming more challenging in general, and superfast pricing under pressure in particular, maintaining/increasing ARPUs is becoming more difficult despite superfast volumes surging

Openreach’s ultrafast roll-out has accelerated, challenging Virgin Media and bringing the prospect of further price premia, but perhaps too late to be of significant benefit in 2019

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
