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

Vodafone Europe’s mobile service revenue growth worsened to -0.6% from -0.2% in the previous quarter, the first deterioration following at least nine quarters of consecutive improvement, with the UK particularly weak

The company could nonetheless grow profits handsomely if revenue growth stabilises at this level, with more clarity on the medium term prospects for this likely to come with next quarter’s results and guidance for 2017/18

Our main concern continues to be the company’s declining subscriber share, particularly in consolidating markets where its historic advantages of having high market share may be rapidly eroded

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

BT had a solid enough quarter, with revenue and EBITDA growth dipping due to pre-warned temporary factors, consumer continuing to outgrow business, and very solid operating trends evident, especially in high speed broadband and mobile

This has of course been entirely overshadowed by the profit warning, with prospective weaknesses in UK public sector and international corporate of far more concern than the contained, albeit surprising, accounting irregularities in Italy

BT has a large share of revenue and a much smaller share of profit from corporate/government data network/IT services, which are erratic in nature and arguably in long term decline in their current form, and without major changes they will continue to be so

European mobile service revenue growth recovered to nearly reach positive growth in Q3, improving a whole percentage point over the previous quarter to -0.2%

The main driver of the improvement was continued ‘more for more’ price increases combined with a lack of price wars at the lower end, although the current detente does not feel very stable. Furthermore, the pressure on growth from the general trend towards SIM-only and the consequent lower contract revenue looks unlikely to alter

Revenue growth of around zero as almost achieved this quarter is sufficient for the operators to grow the bottom line, but not to transform their network coverage in the style envisaged by 5G enthusiasts – more substantial growth is needed to cover the costs of such a step-change

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

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

Vodafone Europe has improved its mobile service revenue growth to near zero (-0.2%), and narrowed its revenue growth gap to competitors to a mere slither (0.2ppts), allowing it to return to significant EBITDA growth (3.1%)

The primary driver for this was however ‘more-for-more’ price increases, which have been followed by competitors only in part, and it is still losing contract subscriber share across its major markets (with significant local variation)

Its overall network performance statistics are flat, and customer NPS statistics are improving in some markets and worsening in others. Future outperformance is possible, but by no means guaranteed, and we believe that stabilising market share should be more of a priority than price rises
