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

Sky’s 16% year-on-year increase in interim profits reflects strong operating efficiencies and reduced marketing costs due to the slowdown of TV gross additions in a tough economic climate, while continuing low churn underlines its product strengths

Fibre broadband deployment and the January launch of streaming-only services by Lovefilm and Netflix signal increasingly competitive conditions, but Sky is well placed and the challenges should take several years to materialise

Sky management is fully aware of the need for its pay-TV business model to evolve in the age of digital convergence, where innovation and building value are prerequisites of success, and is actively addressing the issues

BT’s results for the December quarter saw continuing trends of gradual improvement at BT Retail and efficient deployment of next generation access at Openreach, plus strong control of unallocated property costs, enabling management to issue slightly improved group-level guidance for the current financial year to March

Cash flow growth at group level continued to be compromised by the cost of overseas expansion at Global Services and a continuing shift to LLU and IP-based services at BT Wholesale

Improved guidance suggests that progress at Retail and Openreach is sufficiently strong to generate positive, if modest growth in cash flow at group level, despite the slower pace of improvement at other divisions and a challenging economic environment

With the economy drifting sideways, we have set our centre case forecasts at 0-1% average annual growth in TV NAR and assigned a low probability to a repeat of the hyper-cyclical downturn of 2008/9

Comparative international data show a pervasive long term weakness in display advertising trends across the developed world, while emerging markets in Asia, Latin America and Central/Eastern Europe take an increasing share of global budgets

With digital switchover near completion, channel viewing shares across the main commercial groups should stabilise, but internet advertising, especially online video, will exert a negative structural downward pressure on TV NAR over the next three years at least

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

Rumours that News International will consider launching a newspaper to replace the News of the World have circulated for months, and probably only one event can dispel them

Trinity Mirror has picked up the bulk of the 60% of NoW copies that have not entirely fallen out of the market since June 2011, and arguably the longer any launch is delayed the harder it will be for NI to attract them back

The £150 million revenue once generated by NoW is diminished and dispersed among rival publishers and we estimate that even a triumphant launch would likely generate half to two thirds of the income of the closed title

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

Qatar’s Al Jazeera will launch its French pay-TV channel by this summer, showing weekly Ligue 1 and Champions League games, but it has yet to disclose a business plan and distribution deals

The new channel is a complement to Canal+, which broadcasts the most attractive games. Al Jazeera would need to obtain distribution on the Canal+ platform

Even if such a deal were to be struck, Al Jazeera would struggle to break even

UK households cut their real spending in 2011, and we expect their spending to, at best, flat-line in 2012 and 2013

From an economic perspective, flat real advertising growth is our central case for 2012 and into 2013 for the UK

Poor sales prospects and low profit margins on heavy price discounting will dissuade advertisers from higher spend until tangible evidence of a consumer recovery emerges.
