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

Concrete business applications around the personal data generated by connected mobile devices was a major theme, with new types of automation and personalisation in services and media – and a growing market for security

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 

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

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

21st Century Fox’s (21CF) second attempt to acquire Sky comes at a time when the TV world faces mounting online pressure, accompanied by erosion of territorial boundaries in an increasingly global marketplace 

Despite some investor concerns about Sky’s ability to deliver its operating targets over the next five years, we consider the underlying business to be sound and starting to show benefits that derive from its international scale 

21CF’s bid has a strong strategic logic in terms of growing international scale further and evolving a global platform that integrates shared content strengths in sports and entertainment with Sky’s top of class expertise in customer relationships 

Despite a slowing of circulation decline in 2016, UK national newspaper brands continue to face profound structural challenges, with print advertising spend expected to be down at least -15% for the year

In digital advertising, tech and distribution platforms continue to dominate growth with newspaper publishers and other content producers competing for an increasingly small slice of the revenue pie

In this context, many publishers are turning to paid membership and content subscription models to generate online revenues; success here will require a radical shift in thinking to a retailer mindset that delivers high quality reader experiences through integrated execution of tech, data, marketing and design

The Bank of England predicts a mild decline of real household consumption growth to 2% in 2017, as higher inflation chews at disposable income

City forecasters are more circumspect on consumption growth, and we agree that households are likely to display more caution on expenditure relating to non-essentials

Retail sales, a bellwether for advertisers, look subdued in the New Year, and we maintain our forecast of flat advertising expenditure growth in 2017

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
