We estimate that UK online ad spend grew by 12.3% this year, with growth concentrated almost exclusively in mobile search and social in-feed advertising (particularly video), and mostly incremental to overall ad spend

Even after payments to publishers and distributors, Google and Facebook captured 80% of all net new spend in the market, and 96% of it flowed through their platforms

Despite improving standardisation and disclosure, the outstanding issues around measurement, the ad-tech supply chain, and particularly the obscure and growing Google/Facebook/Amazon segment, lead us to identify a large portion of digital advertising as a “grey market”: difficult to get a handle on, with uncertain beneficiaries and slippery definitions

Children’s media use and attitudes have dramatically changed over the last few years, stemming from the rapid take-up of smartphones and tablets

Traditional TV continues to decline at the expense of newer video services such as YouTube, Netflix and Amazon, with 43% of children aged 8-15 preferring YouTube videos over TV programmes

These online services offer content producers wider opportunities, but questions remain around the lack of regulation online, and the recent scandal around children’s safety on YouTube has heightened these concerns

Digital advertising in the UK has been a phenomenal success story, but a concentrated one, such that many online media companies have not found a sustainable model

User payments are growing, but are currently focused on large, expensive bundles: Spotify, Netflix, the New York Times. This implements a hard division between free and paid and limits the potential audience

Micropayments and microsubscriptions are alternative models which content owners in certain media can use to address more types of demand. Multiple obstacles remain but for many companies the need to experiment has become critical

The development and utilisation of streaming technologies has allowed major SVODs, such as Netflix and Amazon, to attain a growing proportion of video viewing

However, tech is just one of the advantages held by these services: plateauing content expenditure, the inability to retain IP and inconsistent regulatory regimes hamper the efforts of the UK’s public service broadcasters

The localised nature of audience tastes, as well as the diversity of PSB offerings remain a bulwark to aid in the retention of relevance but content spend cannot lag

After a quarter coloured by big, returning series Netflix now has just shy of 104 million subscribers worldwide, with, for the first time, the majority living outside the US

Content expenditure continues to dazzle with $4.2 billion spent in the first half of 2017. Negative free cash flow looks set to hit $2.5 billion for the year, with large upfront payments for self-produced and commissioned content coupling with rights acquisition expenditure to create a library of programmes that necessitates continual subscriber growth

Current international growth is small considering the magnitude of the opportunity, revealing the difficulty of creating sizeable customer bases outside of the West, where competitors are cheaper, US programming less desirable and internet access comparatively limited

After a US debut, Amazon’s marketplace of SVOD services arrives in the UK and Germany, but without the major draws of HBO and Showtime

Unbundling SVOD for premium content strengthens Amazon’s position in the fast-developing connected TV landscape, where Prime Video is taking on Netflix, NOW TV and YouTube

For niche content providers, Amazon Channels provides a new, low-friction route to go direct-to-consumer with a mix of live and on-demand premium content alongside existing distribution strategies

Amazon’s marketing services bring in a growing stream of direct, high-margin revenue, but their main role is still in supporting vendor partnerships

Amazon uses customer profile data to profit from its own media and that of others, illustrating the value of a direct customer relationship in online advertising

In the future, Amazon’s moves into video content and voice interfaces are likely to significantly expand ad inventory, but maintaining the trust of shoppers is not straightforward

Netflix celebrated the 10-year anniversary of its streaming service by posting its largest quarterly rate of subscriber growth, adding just over 7m new subscribers in Q4 2016, smashing its own forecast for the period of 5.2m

5.12m of the new subscribers were for its international services, attributed to acceptance of its growing suite of English language original programs. But growth is just as likely related to the bolstering of overseas offerings with acquired programming, after launching worldwide with relatively small libraries

While re-establishing confidence after a period of doubt when missing targets in Q2, challenges await; most notably concerns around net neutrality, diversifying content genres, and the open question as to how effectively original programming will be able to carry the service
