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

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

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

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

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

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

Brexit poses direct risks to exports to the Continent of regulated services, such as audiovisual (AV) media services, if the UK ceases to qualify for the Single Market

Since 1994, the EU has formalised a ‘cultural exception’ in the World Trade Organisation (WTO) and in all trade agreements aside from the European Economic Area (EEA)

Many countries have emulated the policy since, making it challenging for the UK’s AV cluster to gain significant additional market access from future bilateral trade deals

Snap’s IPO is reportedly pressing ahead as expected, suggesting a remarkably early maturity for the company’s advertising business model

Snapchat creatively adapts the tried and true TV advertising formula, focusing on content, context and audience affinity – this goes against the grain of digital advertising and could unlock new brand budgets for online

After an IPO, Snap’s founders would have the freedom to expand their platform with new content, distribution channels and even devices
