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

France’s first round of the presidential election on 23 April looks set to deliver a run-off on 6 May between nationalist Marine Le Pen and pro-EU, pro-NATO reformer Emmanuel Macron, who holds a 20 point lead in that contest – a much higher margin than last year’s mistaken projections for Clinton and Remain

Should Mr. Macron become president and win a majority in the June parliamentary elections, a challenge for nascent party En Marche!, his reformist platform would tackle France’s main economic issue: low employment. The anticipated privatisation of Orange could launch a burst of media and telecom M&A 

A defeat of Marine Le Pen and a new reformist French government could relaunch the partnership with Germany, making the EU more confident in its future, and improving auspices for a sensible Brexit

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
