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

Virgin Media successfully ramped up its network extension in Q4, passing more than double the homes in the previous quarter, and above the rate required to meet 2017 expectations

Net customer additions were, however, relatively weak, entirely due to extra churn caused by the price increase implemented in the quarter. The price increase’s effect on ARPU and revenue growth was muted by ARPU discounting for new customers, leaving revenue growth broadly unchanged

Subscriber growth has already improved in early 2017, and is likely to continue to improve through the year. The discounted ARPU impact will be more sustained, but robust revenue growth is still likely throughout the year

TalkTalk had a weak quarter, as was pre-warned, with the decline in the broadband base accelerating and consumer revenue growth of -6% slightly worse than the previous quarter

Guidance was however very bullish, with the company confident that it can bounce back to return to positive net adds in the March quarter, while still hitting its profitability guidance

This looks a difficult task in a market which is still highly competitive, but if it can achieve it, the longer term aim of a stable customer base and growing revenue and profits looks much more plausible

Enterprise cloud computing democratises access to IT capacity ranging from specialised software to platforms to infrastructure, transforming cost structures in sectors like media and retail

Cloud enables unprecedented scalability of bandwidth for digital media services like Pokémon Go and Netflix, while also hosting the back-end for advertisers and retailers 

As the industry consolidates quickly, intense competition among Amazon, Microsoft and Google is delivering value to customers and boosting adoption

Streaming is now mainstream and we predict 113% growth in expenditure on subscriptions for 2015-18 in the top four markets (US, UK, Germany and France)

Free vs paid-for streaming is the central question for the music ecosystem: free yields fractions of pennies, making subscription the only credible business model

Market leader Spotify is facing competition from tech giants Amazon, Apple and Google, with deep pockets, for whom content is a pawn in a larger game

UK mobile service revenue growth improved in Q3 to -0.8% from -1.7% in the previous quarter, a welcome turnaround after three quarters of declining growth. Pricing remains firm, data volume growth remains robust, and some of the one-off factors affecting the previous quarter have dropped out

Sky Mobile soft-launched at the end of 2016, and it is taking an aggressive approach with a very deep MVNO technical model with substantial fixed costs, a high advertising budget and ambitious internal subscriber targets. To date the fixed MVNOs have not had a substantial impact on the MNOs, targeting a customer base that is non-core, but with SIM-only on the rise this may change

Looking at recently released network performance statistics, the impact of spectrum disparities is clear, with EE both able to offer faster speeds nationwide due to its large blocks of 4G spectrum, and offer much faster speeds in London. EE also has a lead in geographic coverage, and is planning to push its coverage much further, creating a challenge for the other operators to keep up

UK residential communications market revenue growth accelerated to 5.8% in Q3, from 5.0% in the previous quarter, helped by an overlapping price rise at BT, and supported by firm pricing and accelerating high speed adoption elsewhere

In contrast, volume growth in the core three products continues to slow, with little sign that this will ever re-accelerate. In the longer term we cannot see ARPU growth acceleration continuing to fully compensate, and market revenue growth might also have peaked

With Virgin Media’s continuing network extension and improving pay TV service putting pressure on the other operators, Sky and TalkTalk are protecting themselves by aggressively marketing high speed broadband. Correspondingly, this quarter marks the first time that Openreach’s high speed net adds were mostly derived outside of BT’s retail divisions

As smartphone ownership nears saturation in almost all consumer groups, the base for the UK digital economy is widening: media consumption continues to move to connected devices and use of consumer services on mobile grows

Ecommerce is now responsible for 75% of retail growth, steady even during periods of decline for the overall market

Google and Facebook take up almost 90% of gross online advertising growth this year, and the ecommerce and mobile service markets show early signs of platform concentration

UK digital advertising has enjoyed strong growth in 2016, with forecast growth of 12.7% for the full year, just scraping under the £10 billion milestone

However, this growth is highly uneven, being led by mobile display and mobile search, while desktop spend looks set to decline by over 5% year-on-year. More significantly, 90% of the growth is accruing to the two big players: Facebook and Google

Cross-device campaigns, the convergence of marketing and advertising functions, and new consumption trends all threaten our traditional categorisations of online ad spend

US entertainment groups have not been disrupted by the rise of digital media. Long running franchises drive growth across diverse sectors, starting with pay-TV and SVOD. US television advertising is rising in line with GDP, while the online video ad market is flourishing, with much appearing alongside the majors' scripted content

Studios' cable channels are their most profitable assets, but M&As with distribution platforms, including Comcast's aquisition of NBC Universal, have usually failed to deliver synergies

The Donald Trump presidency could leverage hostile public opinion towards mergers to undermine the AT&T bid for Time Warner; but it could also stimulate M&As if it granted tech companies a tax break to repatriate profits. A more protectionist administration could also bring about a less benevolent attitude towards majors' foreign operations
