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

Even though Facebook is not a producer of news, 6.5 million UK internet users claim to mainly source their news from the platform. Posts and shares by friends in the user's network, in the context of Facebook's algorithm, determine the order of stories in the personalised News Feed, removing the control of the news agenda that publishers have for their websites

Premium publishers operating a paywall (The Times, The Financial Times) have a lower key approach to Facebook than publishers generating advertising revenue from referral traffic to their websites or from on-platform consumption of Instant Articles. The latter will seek to stimulate social media engagement, optimising stories through attention-grabbing headlines, and installing Facebook’s share and like buttons on their websites

Case studies of the news stories that were prominent on Facebook (measured by likes, comments and shares) in the periods leading up to the Brexit Referendum and General Election 2017 votes respectively demonstrate that newspaper brands (the Express for Brexit, and The Guardian for the General Election) achieved the highest reach on Facebook during these periods, despite being ranked below other news brands (BBC in particular) in terms of traffic to their websites

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

Facebook content shares suggest that misinformation had broad reach during both US and UK political campaigns, but outright fake news was rare, particularly in the UK 

Mis- and disinformation by both established and new publishers was distributed on Facebook, but monetisation took place predominantly off-site, and content was distributed by a wide range of search and social platforms 

Facebook has acted to limit the reach of disinformation, but can’t and shouldn’t be expected to do so alone as digital news distribution touches on complex questions including information and democracy, media literacy and heterogeneous cultural and social norms

The successful launch of the Nintendo Switch creates a new console model, and demonstrates the staying power and long term value of great franchises

Microsoft reveals the specification for Scorpio, but it won’t be enough to catch up to Sony. New franchises, and probably new leadership, will be the key to stopping Xbox sliding into irrelevance outside North America

Sony’s PlayStation 4 now exceeds 60m units worldwide, allowing Sony more freedom to publish a wide range of challenging creative console games, while VR games continue to gain momentum

Cross-device identity profiles are used to stitch together fragmenting online ad audiences, but also to enable new links between advertising and marketing, across European markets

This moves value from media itself to understanding each consumer and how they access content and services on proliferating connected devices

By 2020 we predict that 58% of all UK online ad buys by value will make use of high-quality audience IDs, led by the largest advertising platforms but limited by privacy regulation and cost

Fashion underpins the growth of ecommerce; online took a 14% share of all fashion retail in the UK last year and is set to rise further, challenging the economics of physical retail 

Mobile is a key driver, it is changing research and shopping habits, and in turn affecting supplier product cycles, merchandising and marketing strategies 

Social media has disrupted the traditional shopping funnel, changing how trends and styles proliferate and shifting the sites of authority and influence in a £66 billion sector

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
