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

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

Across Europe, markets are becoming more competitive. Incumbent pay-TV paltforms (e.g. Sky or Canal+) face increasing threats from both internet-based services (e.g. Netflix and Amazon), and telecoms operators

Telecoms providers are proving the most potent challengers as they enter the premium football rights market to create attractive triple and quad play bundles – examples include BT, SFR and Telefónica. The latter is now the main pay-TV operator in Spain whereas France’s Canal+ has entered into a strategic alliance with Orange

Across the top five markets (UK, France, Germany, Spain, and Italy), Sky remains the leading operator with an estimated 21.5m video subscribers, twice as many as Netflix

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

Media reports of ads by top brands appearing next to extremist content on YouTube have surprised advertisers and led to a barrage of criticism from other media companies, agencies and the UK government

Despite several advertisers pausing spend, the revenue impact for Google is likely to be small in the short term – but the debate is a symptom of ongoing tension between “frenemies”: large agencies and Google & Facebook 

By urging Google alone to educate display advertisers and filter campaigns, agencies risk ceding more of their client relationship to the advertising giant, while calls for the platform to make all editorial judgements on political content are inappropriate

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
