Over Q2, the value of online sales (excl. fuel) grew by 55%, whilst offline sales (excl. fuel) declined by 22%. Three months of lockdown has accelerated ecommerce by four years and households will spend more than ever before online, post-lockdown.

The rapid shift to ecommerce poses lofty challenges to UK retailers who have historically been timid in their approach to ecommerce. Integration between sales channels will become more important than ever before, but very few have managed to perfect this approach.

As more retail activity takes place online, ad products from the likes of Google, Amazon and Facebook stand to benefit greatly, pulling spend from other ad and marketing budgets that were aimed at driving in-store behaviours.

Online reviews are a vital input for consumer decision-making. However, reviews are easy to manipulate, and widespread fraud is undermining credibility and raising the issue of consumer protection.

Facebook, Google, and Amazon utilise reviews to improve the consumer experience, but also to sell advertising to businesses and to address fraud. These companies leverage their data superiority to better utilise reviews on their platforms, and possess a competitive advantage, versus sites like TripAdvisor, Yelp, and eBay.

Demand for expert opinion remains strong, yet is supplied only by publishers and Which?, a small segment in terms of share of traffic relative to platforms.

Microsoft dominated PCs and Nokia mobile phones, but both are irrelevant in the dominant model for tech in the next decade, smartphones and tablets. An acquisition may have been necessary, but by itself it solves nothing.

Smartphones are now half of all mobile phone sales, and the 255m smartphones and tablets sold in Q2 2013 dwarf the 76m PCs sold. Microsoft now powers less than a quarter of all the personal computing devices being sold.

Microsoft retains a leading position in enterprise and in console gaming. But if it cannot return to relevance in consumer, the strength of the whole business will suffer.

Amazon, Nokia and Apple are expected to announce new mobile devices in the next fortnight. We outline the main products and features expected and their implications

Around 125m smartphones were sold globally in Q2, up over 30% from Q2 2011. Around 450m mobile handsets were sold in the quarter, giving smartphones a volume share of around 28% Apple and Android dominate with a combined of 85% of units sold, and a cumulative total of 810m devices running their mobile platforms. Of these we estimate that 680m are active, of which 95m are tablets Android arrived later and has grown faster, but Apple’s market share of smartphones as been steady at 20-25% for several years: Android’s growth has come at the expense of Nokia, RIM and feature phones

Nokia has launched its comeback with two very solid Windows Phone devices at €420 and €270. Next year Nokia, like Apple, will have handsets with uniquely appealing industrial design. However, Nokia will not launch in the USA until 2012 and needs to add cheaper smartphones to the portfolio

Nokia and Microsoft face a hard struggle in establishing a third mobile app ecosystem. However, it is not impossible (Google has managed it in 18 months) and given more devices and the right execution they could manage it

2012 will be the critical year. We believe that the flaws in the Android proposition mean there remains a real window of opportunity. However, if Apple launches a cut-price iPhone then the market will be turned upside-down, again

In this report we outline the current state and likely development of the war between mobile platforms. We discuss installed bases and activity levels, the key issues facing Apple and Android, including Android fragmentation and Google's acquisition of Motorola, and go on to look at the tablet market and the outlook for RIM, Nokia and Windows Phone.
