For much of the online media industry, GDPR compliance has stalled at basic data audits and box ticking, as firms wait for the rest of the privacy regime to emerge

But weighing technicalities of legitimate interest and consent misses the point: transparent consumer value will be the only sustainable basis for processing personal data

The scrutiny of Google and Facebook privacy practices involves an added antitrust dimension, potentially leading to processing limits as remedies

European mobile service revenue growth was unchanged this quarter at 0.3% growth, despite an easing of the European roaming cuts impact. This was due to intensified pricing competition in Italy and Spain, and EE’s unexpected poor performance in the UK. France and Germany were the only countries to improve their growth, but the improvement in France was largely due to a revenue-boosting VAT loophole

More-for-more price increases continued during the quarter, but their implementation is increasingly dependent on market conditions. Zero-rated streaming offers have continued to launch, but remain the exception rather than the rule.  Given the long implementation periods required for innovative new products at most operators, this may be temporary

Looking forward, overall the outlook looks finely balanced with boosts from the reduced MTR impact in Germany in Q1 2018, an easing in Spain’s retail pricing pressure and EU roaming impact annualising out by Q3 2018. This is countered by France closing its VAT loophole, steep MTR impact in Spain in Q1 2018 and continuing intense competition in Italy given Iliad’s impending launch

Engineering excellence and user generated content (UGC) have propelled YouTube to Facebook-level reach, with growing viewing in all demographics and on the TV-set

However, the commercial limits and PR risk of its long-tail content model have prompted a diversification effort involving subscriptions and long-form content

Becoming a major part of Google’s revenue amid fierce OTT competition would require YouTube to be more flexible in its partnerships with the AV industry, and a more aggressive go-to-market strategy

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

European mobile service revenue growth declined this quarter to 0.3%, likely due in large part to the increased negative impact from the European roaming surcharge cuts, which we estimate at around 0.5-1.0ppts for Europe as a whole

The continued growth was supported by continued ‘more-for-more’ price increases coupled with strong data volume growth. Partially countering this, there has been a step up in competition at the low end in some markets, often driven by the smaller operators

Looking forward, the negative EU roaming impact is likely to decline from next quarter given the end of the summer holiday season, and on balance we would expect positive price increase trends to overcome negative low end competitive trends, at least in the short term. This might change in 2018, as Iliad launches in Italy, and recently consolidated operators become more of a threat

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
