Netflix gained 1.8 million accounts in the course of 2015 (+37%) to 5.2 million, surpassing the 1.3 million VOD-enabled homes added by fixed line telcos Sky (including NowTV), Virgin Media, BT and TalkTalk. SVOD homes overlap with pay-TV accounts, and are topping up content for family members, not cord-cutting

Amazon Prime Instant Video, bundled into Prime, looks set to balloon from 1.6 million users in Q4 2015 on the back of the marketing of Jeremy Clarkson's motoring show, cementing its position in home entertainment by serving a family-friendly eco-system of devices and media, leveraging its mammoth 25% share of UK e-commerce

Free-to-the-user YouTube remains the heavyweight with 35 million monthly unique users in the UK, although skewing strongly to Millennials, while those 55+ will take longer to move beyond catch-up TV to embrace a wider range of VOD options

Native advertising is growing sharply as a result of the shift in digital audiences and consumption to mobile devices, where limited screen size and usage modes favour formats that mirror the form or function of the platform and media

Publishers and advertisers are moving rapidly to exploit the opportunity. Publishers see unique native formats as a way to distinguish their ad offering in a highly commoditised internet advertising space, while advertisers and their agencies hope to get more bang for their buck

Between 2015 and 2020, we expect native advertising spend across Western Europe to grow by 156% to €13 billion, representing 52% of internet display and three quarters of net growth in internet display

This year marked the second annual IABUK Digital Upfronts. As well as Facebook, Google/YouTube, Aol, Yahoo!, Twitter, BuzzFeed, Vice and others, several traditional media companies – Sky, The Guardian and Global Radio – participated, reflecting the rising importance of digital media and digital media buyers to their businesses

Many of the pitches were informed by the key shifts in online content: it is increasingly cross platform, driven by mobile devices and focused on video programming, and these formed the main themes of the event

A key piece of context is the rise of social media and the shift to programmatic buying, which continue to driven down pricing for all but the most valuable inventory – audience scale, high value audiences and premium content have never been more essential

At launch, Google’s new subscription service YouTube Red competes most directly with premium music streaming services, also offering ad-free videos

YouTube’s augmented revenue model re-boots incentives for native talent to produce content for the platform, and will also widen its appeal for established content producers

Although consumers are likely to find paid subscription for ad-free videos a weak proposition, Red holds much potential for YouTube as it competes for attention across device ecosystems, and presents little risk to its existing advertising model

Despite dropping the Fire Phone, Amazon has upped the ante in its battle for digital media consumers, upgrading its Fire TV devices and rolling out a new range of low price and robust tablets, starting from £50/$50, squarely aimed at the mass market

As with all Amazon devices aside from the failed phone, they are conduits for the company’s media and retail services, aimed at increasing purchases and forcing other platform operators to include them

Although shrinking as a share of Amazon’s business, media remains crucial, both for direct revenue and to attract customers to Prime, its membership programme, which by some estimates now accounts for the majority of its US sales

Consumer ebook sales exploded after Amazon launched its Kindle in the UK in 2010, but growth rapidly slowed, and disruption was limited by genre, creating parallel ebook and physical book markets

Compared to the relentless downward spiral of music purchasing, these trends have been heartening for publishers and booksellers, but there are signs that slower, more complicated and insidious disruption is emerging

Decades of steady, albeit slow, growth in total book sales have been reversed, as consumers spend more time on a variety of mobile-delivered services, including some in classic content categories for books

The latest numbers for Q1 2015 show strong device and internet user growth, with more of the population online than ever before, including more than 90% of under-55s. Growth amongst older groups, however, has slowed to a crawl

Participation in online activities is up across the board, but digital media data shows spend on ebooks and digital music struggling, with the latter being heavily impacted by the rise of unlimited streaming models such as Spotify

The story of mobile's surge continues, with almost a half of e-commerce transactions and a third of search and display ad spend now going to mobile. Most of these mobile devices are Android, but iPhone seems to have gained long term share with its larger phones. Google services, however, have cross-platform reach

Recently we attended the inaugural IABUK Digital Upfronts, in which 11 digital media companies pitched their wares to advertising agencies and advertisers.

UK growth in internet advertising is now powered by mobile, social and video, and these three areas were the focus of the Upfronts.

The Upfronts are symbolic of the rising importance of digital media in the UK and worldwide; while broadcast television remains the king of brand advertising, marketing and advertising are becoming less TV-centric.

2013 has seen yet another year of strong growth in consumer adoption of mobile devices and screens adding to the challenges facing traditional media. Press and radio have long been affected, but television is now starting to feel the heat

BT and Sky’s contest for premium pay-TV sports rights has intensified. August saw the launch of BT Sport, while BT’s acquisition of the European football rights in November was a clear statement of intent, spending half of Channel 4’s total programming budget on approx. 200 hours of content

The UK has seen buoyant advertising growth of around 4% in 2013, with similar growth expected in 2014, in the context of the strongest economic recovery in Europe

Search remains the main engine for Google’s core business, but display is rising fast: we estimate display gross revenue will reach $9.2 billion in 2013, representing 16% of projected gross revenue (excluding Motorola)

Gross revenue from YouTube looks set to more than double to nearly $4 billion by 2013. Revenues from Google’s ad networks and platforms are also growing strongly, mainly to the benefit of publishers

We project Google’s net revenue from display next year will amount to $4.2 billion, equal to 10% of net revenue from its total advertising business
