In this report we develop a rough segmentation of the adult population by level of online use: offline (10% of adults), shallow online (10%), deep online (80%). We examine how online services seeking to reach new audiences increasingly face the obstacle of missing demand rather than a lack of consumer skills or access

The app economy still relies on a limited consumer pool, but ecommerce is now reaching almost all of the deep online. Bridging the current gap between occasional and frequent online buyers is a clear opportunity and we are still in the early days of evolving buying services into shopping services

The only industry monetising all online users is advertising. Ad platforms, led by Google and Facebook, also play a critical role expanding the ranks of the deep online and online immersed. But offline brand display media, led by broadcast TV, remain critical for online brands wanting to expand their audience

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.

Almost half of Facebook’s impressive revenue growth and turnover is still reliant on the US, where user growth has slowed down

Among GAFA platforms, Facebook’s core business is the one most directly dependent on dwell time, but the metric for the crucial home market is clouded in mystery

The company has yet to create significant compensating revenue streams outside display advertising, raising the importance of international markets for Facebook’s future

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

Through innovations in processing, connectivity and cameras, Apple’s new device lineup dispels fears that the importance of integrated, profitable mobile hardware is in terminal decline

With the broadest range of iPhone price points ever, Apple is confidently balancing between profits and growing the valuable installed base

Apple’s long way to an AR future is now well paved, but a weakness in mapping could prove to be an Achilles heel

For the second consecutive year, the global recorded music industry body IFPI reported rising trade revenues, growing 5.9% to reach $15.6 billion in 2016

Our forecasts supplement IFPI’s trade revenue data with richer national-level consumer expenditure data from local bodies in core markets, and project CAGR of 2.3% to 2021, tapering off as streaming approaches maturity

This fairly modest topline growth for global recorded music streaming trade revenues is the product of our judgement that the marketplace remains awash with free music. Streaming trade revenue growth could be higher still if the industry finds a solution to piracy through technological or regulatory means, obviating the need for the ad-funded compromise

With smartphones in the pockets of 3/4 of the UK population, and accounting for over half of all online minutes, the mobile revolution is in its final stages, allowing us to survey its impact

As the number of social media users continues growing, untapped older demographics and Instagram help the Facebook suite of apps grow in the UK, but Snapchat is the social media app of choice for UK teens

News publishers face issues with brand attribution as social media platforms overtake search as the main news aggregators online, while small UK video publishers have become unlikely winners in a global market for soft news, infotainment and gags that dominate social video
