Even with the decline in linear television viewing, online video remains a small component of total video consumption. The growth area is unsurprisingly SVOD; subscription video now makes up about two thirds of the UK's digital video spend.

Netflix is moving from an aggregator of content to a "channel" in its own right, increasing proportionate spend on original programming, something that the public service broadcasters are unable to do for differing reasons. Amazon had a tough 2017 for video, and are still struggling to create a hit.

New Nielsen audience data suggests that the long-term "library value" of Netflix's originals may be overstated, while the BBC's iPlayer continues to be hampered by not really having a library at all.

The slowing UK economy since Q3 2016 has had a knock-on effect on the property and autos marketplaces underlying UK classified advertising revenues, with house prices slowing, transactions stabilising (instead of rising), and new car registrations down sharply in 2017 to date. Recruitment activity by agencies and employers has instead been dynamic as the UK nears full employment

Advertisers in these verticals continue to switch expenditure from print classifieds to internet portals and search, which offer superior lead generation, analytics, and user experience. Only in property do local newspapers still fulfill an important estate agency branding function for the local area, although declining readership is blunting this value to advertisers

Portal dominance comes at a price to advertisers in property, where Rightmove has resisted agent efforts to lessen dependence by listing on other brands, as well as in used autos, where Auto Trader has long reigned supreme. Recruitment is a more contested market for portals, reflecting the diverse and fragmented nature of the jobs market, but Indeed has a strong grip on the low-end, while LinkedIn remains unchallenged in social recruitment advertising

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

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

Google has beaten Facebook in mobile revenue growth, and competes successfully in retail search with Amazon

Intelligent user interfaces based on machine learning have become a core competitive strength, with social and messaging the main remaining weak points

Rising political pressure due to Google’s growing scale and influence is now a bigger concern than commercial risk, as the threat of regulatory intervention limits strategic options in partnerships, M&A and integration

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

Voice, and the smart virtual assistants that power voice interfaces, will be a key transformative force over the next five years

Any business providing content or services via digital means is potentially affected, as these virtual assistants promise a single front end for all digital services, representing an extraordinary concentration of control over discovery, delivery and data

Media businesses will clearly be affected. But there is an opportunity for them right now to influence the assistant providers to their advantage, a window that will not stay open forever

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
