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

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

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

Snap is going public: its filing shows widening losses and slowing user growth, calling into question its ability to reach profitability and justify the ~$20 billion valuation it is seeking

Long term, the company hopes to capture the large brand advertising budgets it expects will leave TV as linear viewing declines. But how it plans to do so is unclear, as it has shown little interest in connected TVs, and the ad model for augmented reality – Snap’s focus – is a long way off

Most of all, investors are being asked to trust in the ability of Snap’s founders – who will retain full control of the company – to continually innovate products which will attract users and advertisers

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
