Google+, the social network, has around 100 million users worldwide, although user growth appears to have stalled and usage is low on weak network effects

Facebook users, now 70% of the adult internet audience (excluding China), have no incentive to switch to Google+, starving the social network of vital momentum

Facebook is likely to dominate socially enhanced search, unless Google+ takes off, which seems unlikely

In this presentation we show our analysis of revenue growth trends for mobile operators in the top five European markets (UK, Germany, France, Italy and Spain). The historical analysis is based on the published results of the operators, although they include our estimates where their data is inconsistent or not complete. A copy of the underlying data in spreadsheet format is available to our subscription clients on request.

Mobile operators, services and handset makers are diverging – they all come to the MWC but have increasingly little to say to each other as their businesses move in very different directions

In the context of -5% European mobile revenue growth, the MNOs at the MWC were a sober bunch, focusing on industrial services, defensive moves around messaging, and a (not unreasonable) plea to regulators for some relief

As competition in Android intensifies between hundreds of black plastic rectangles, the picture for OEMs looks tough but Google’s failure to make Android work well for developers may also start to bite, leaving an opening for Nokia and Windows Phone

Apple refreshed the iPad yesterday, delivering few surprises, a market leading product and a set of features that we expect to ensure continued dominance into 2013

Three drivers are increasing UK internet consumption: a growing number of older PC internet users; digital natives, especially younger people with high incomes, spending more time online; and rising adoption of the mobile internet

Despite rapid mobile user growth, internet usage remains a PC-centric experience as time spent on mobile is constrained by screen size, ‘on the go’ use and data pricing. These factors are less likely to inhibit tablet use

Everyone uses the internet as a retail, communications and information service and traffic is growing as older users come online. But under-35s are increasingly using the internet as an entertainment destination as well, sharing video content on social networks and driving a huge increase in time spent on YouTube

Facebook’s IPO prospectus confirms that the social network is an internet colossus, with 845 million users worldwide and $3.7 billion in revenue in 2011

Growth potential in display advertising, which accounts for the majority of revenue, seems limited with increasing mobile substitution in major ad markets and future user expansion largely in lower yielding countries

There is significant potential to increase income from payments and other businesses beyond social games, but the company’s strategy is unknown at this point

Around 125m smartphones and over 20m tablets were sold in Q4 2011. If tablets are included, Apple is now the largest PC manufacturer, while smartphones are now outselling PCs

These devices are the battleground for a war of ecosystems in which Apple’s iOS and Google’s Android platforms are dominant and others are hoping for third place at best. iOS and Android sold around 92m units in Q4 and now have an active base between them of around 515m devices

Samsung now accounts for at least half of Android sales and is in some senses more of a rival to Apple than Android itself

Apple has begun selling interactive textbooks via its iBookstore, a move which is likely to accelerate the digital transition in education

However, the pace of change will be slowed by the cost of devices and the limited number of textbooks that have been designed for tablet computers

By developing educational software and course materials, Apple is trying to position the iPad at the centre of students’ educational lives – a niche that could significantly boost its hardware sales

US album volumes in 2011 rose for the first time since 2004, but lower pricing may continue the revenue decline

UK album volumes declined 5.6% in 2011. HMV’s new-found breathing space removes a key risk for the outlook

US radio royalties to music publishers have been agreed in principle and will see a return to a revenue based payment

Google’s UK revenue grew 23% to £676 million in Q4 2011, taking 2011 revenue to £2,525 million, up 20% year-on-year, 2 ppts below our November estimate

Globally, gross revenue rose 25% year-on-year, with mobile and display performing strongly, but rising costs pulled net revenue growth down to 8%

Our growth forecasts for Google’s UK revenue remain unchanged; we expect UK internet ad spend to rise from £4.7 billion last year to £5.8 billion by 2013, representing 35% of total advertising, as print continues to fall
