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

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

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

Many European telecoms operators are pursuing a fixed/mobile convergence strategy on the pretext that the addition of mobile reduces churn. We see no evidence of churn reduction from this strategy

Discounts required to encourage take-up of fixed/mobile services are often value-destructive, even before competitor reaction: a 10% bundle discount necessitates a 2ppt improvement in churn to wash its face economically. M&A premia on the basis of convergence synergies raise the hurdle even higher

Most UK operators offer very limited discounts on fixed/mobile bundles for now, sensibly focusing on enhanced services. Vodafone is the most aggressive, albeit less so than it is elsewhere. All UK players should hope that it stays this way

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

Sky posted yet another set of solid results, with revenues up 5% and operating profits up 10%, despite weakening operating metrics in Germany & Austria

Deals with Netflix and Spotify will enhance the customer experience, signalling Sky's confidence in its platform, perhaps a sign of further deals to come

A successful outcome from February’s Premier League auction sealed the prospect of a takeover battle for Sky, with Comcast launching its formal bid this week
