Smartphone hardware did not take centre stage at the year’s premier mobile industry event in Barcelona, with license-built Nokias generating as much excitement as flagship smartphones from HTC, Sony and Samsung

In VR, AR and IoT, the most impressive signs of progress were under the hood rather than in flashy device announcements – as the actual use cases become more specific, so does hardware and software

Snap is going public: its filing shows widening losses and slowing user growth, calling into question its ability to reach profitability and justify the ~$20 billion valuation it is seeking

Long term, the company hopes to capture the large brand advertising budgets it expects will leave TV as linear viewing declines. But how it plans to do so is unclear, as it has shown little interest in connected TVs, and the ad model for augmented reality – Snap’s focus – is a long way off

Most of all, investors are being asked to trust in the ability of Snap’s founders – who will retain full control of the company – to continually innovate products which will attract users and advertisers

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

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

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
