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

Sky maintained strong revenue growth of 5% in 2017/18, with EBITDA and operating profit both bouncing back into strong positive territory after the UK Premier League rights hit of 2016/17

The UK grew revenue well and profits better; Italy performed well and should improve much further given the retreat of its principal competitor; Germany is more challenged, but extra content investment may aid sustained growth

Sky is proving adept at managing content costs and revenue in a changing environment, with investment, cost control and monetisation all being put to effective use as the content type demands it

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

Sky H1 results were very solid, maintaining 5% revenue growth and 10% EBITDA growth, with Sky continuing to support a widening product portfolio and more expensive core products with strong cost control and execution

Subscriber volume growth was a little weak at the margin, but this will be helped by all-IP products expanding the economically addressable base in new, and existing, markets 

There remain questions on content, with the outlook for premium football rights uncertain in the UK and Italy, and investment in Originals questionable given a mixed track record, but certainly with upside
