Mobile sector returns are low, particularly for smaller-scale operators, with H3G earning less than its cost of capital. Regulatory initiatives, spectrum auctions and 5G look set to worsen this picture as H3G strives to gain viable scale

Back-book pricing is crucial to the returns of fixed challengers. Regulatory intervention is likely to lead to a waterbed effect in the fixed sector and exacerbate challenges in mobile

New entrant business case in full fibre is limited to de facto monopoly opportunities. There is the potential for BT’s returns to increase markedly if it gets full fibre right but new entrants’ inferior economics are unlikely to offer sufficient investor appeal

Spotify is investing heavily in podcasting through acquisitions, original content and product innovation

It is under pressure to reduce dependence on record labels, whose power makes generating large profit margins difficult. Podcasts promise a non-music content genre where Spotify can capture more value

Secondary benefits abound: Spotify can take an active and lucrative role in modernising online audio advertising, it can solve the podcast discovery problem, and engagement across more forms of audio will improve retention

Ofcom’s recommendations to Government suggest updating EPG prominence legislation to cover connected TVs, and were warmly welcomed by the PSBs

Balancing various commercial, PSB and consumer interests will be key; determining what content qualifies for prominence will be a particularly thorny issue to resolve

Extending prominence to smart TVs and streaming sticks is critical, but implementation will be challenging

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

Audiobooks are growing fast, driven by smartphone adoption and better supply, as well as interest from people who don’t usually buy books, such as young men

The sector is dominated by the presence of Audible, Amazon’s audiobook publisher/retailer, which has driven growth of audiobooks but put publishers under pressure. Its strategy is a lesson in Amazon’s approach to media

Audio is an opportunity to sell to new customers, but publishers must acquire and use rights responsibly, and experiment while not letting the audio tail wag the print dog

Spotify is now the world’s first publicly listed on-demand music streaming service. Its global footprint generated €4 billion in 2017 from over 70 million paying subscribers and 90 million ad-funded users across 65 countries

As it expands, the service is steadily but surely moving ever closer to profitability, with a 2019 operating profit a very real prospect

So far and for the near future, Spotify’s global pre-eminence versus competition from Apple, Amazon and Google proves remarkably resilient. Plans to build upon its differentiating features will become ever more decisive as the tech titans will continue to wield their resources and ecosystems against the comparatively undiversified company
