In the last few quarters the iPhone has grown to 50% of total smartphone unit sales in the USA, while smartphones overall are now around 42% of the installed base

In the last 12 months we estimate US mobile operators spent around $15bn subsidising iPhones, slightly under 9% of their revenue

The key factor driving increased US iPhone share is increased distribution: it was over two thirds of AT&T’s reported smartphone sales for each of the last 8 quarters, but AT&T only had a third of the market; when Apple added Verizon Wireless in Q1 2011 and Sprint in Q4, it immediately took over half of their smartphone sales as well, powering it to 50% of total US smartphone sales in Q1 2012

CPW’s key operating metrics worsened again in the March quarter, with connection volume growth dropping to -19% and like-for-like revenue growth dropping to -5.5%

Weakness in the UK prepay market continued to affect CPW’s results, with volumes again down 30-40%, but contract sales did not mitigate this as much as last quarter, with growth in the UK but declines in continental Europe

Prepay is not likely to improve until the end of 2012, as the volume decline annualises out and more smartphones are available at prepay price points, and contract recovery is dependent on economic recovery

EE’s subscriber growth in Q1 was solid enough given a market slowdown, but disappointing given T-Mobile’s Full Monty tariff launch. With O2’s ‘On and On’ launched in late March, the outlook for subscriber growth will be tougher in the rest of 2012

Service revenue growth was more encouraging, improving by 1.5 ppts after a disappointing Q4. This appears to have been largely volume driven (i.e. existing users using their handsets more), which is encouraging for the operators yet to report Q1 figures (i.e. Vodafone and O2)

The company’s main competitive weapon going forward should be the quality of its network – even post-consolidation it will have more 3G sites than any other operator and may be able to use its 1800MHz spectrum to gain a head-start in 4G. However, communicating that both brands have an outstanding network, without encouraging subscribers to migrate to the lower-priced T-Mobile, will be problematic

UK mobile advertising jumped 157% year-on-year to £203 million in 2011, marginally higher than our forecast of £180 million, with strong growth in both search and display

Mobile advertising now accounts for 6% of internet search and display spend, but still lags mobile devices’ share of internet consumption, which has been rising strongly due to rapid smartphone and tablet adoption, and we estimate is now at around 15%

We expect much of the lag between mobile’s share of internet consumption and ad spend to disappear over the next five years, indicating continued high growth

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

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
