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.

CPW Europe had a weak first quarter, with like-for-like revenue growth of -3.3%, with all of the drop coming from the 18 to 24 month contract length shift in the UK

We expect its performance to improve through the rest of its fiscal year, but it will need to in order to hit even the bottom end of its full year guidance

The US mobile retailing operation is doing much better, with very strong revenue growth, and is likely again to exceed full year guidance

Apple has now sold 25m iPads since launch, worth $15bn, and will probably sell 40-50m in 2011. Competing tablets have sold perhaps 2-3m in total so far and will not be competitive with the iPad until 2012 at the earliest

Android phones are now far outselling iPhones, but benefit from a narrower user experience gap and from selling at a half of the price. Android tablets must compete with the iPad at the same or higher price points, a far harder task. We believe it is possible the iPad will retain a 50%+ share

Media companies have veered from euphoria to outrage when contemplating the iPad and its autocratic creator. Android offers them little chance of either in the near future

Amazon now sells more ebooks than print books on Amazon.com, while overall US ebook sales were 15.6% of the consumer market in March, up 142% from last year. Meanwhile, for some publishers over half of book sales are now through companies that are not book sellers

Waterstone’s has been bought by a Russian investor for £53m, with James Daunt parachuted in to take it back to its roots in bookselling, while in the USA John Malone has bid for Barnes & Noble valuing it at $1.45bn

As book buying moves away from bookshops and away from print, both retailers and publishers will need to rethink both their scale and the way that they engage with readers. Beautiful shops and beautiful apps are probably an insufficient response

CPW Europe had a difficult quarter, with volumes falling 9% and like-for-like revenue 2%, due to continued prepay weakness and the shift to 24 month contracts in the UK

The US business was again very strong, growing volumes at 26%, and this strength is likely to continue due to an acceleration in store roll outs

Keeping the European business flat in 2011/12 will be a challenge, but the US business is likely to more than make up for this at the group level

Market data and industry anecdote point to an explosion in ebook sales in the US and UK in 2011. Leading consumer publishers are seeing ebook sales at 10-15% of total sales in January and February, driven by Christmas device sales

So far ebooks had been strongest in niches: romance, business books and frequent travellers. They have now moved into the mass market: few genres will be untouched

This shift brings with it a very different market structure, with Waterstones likely to shrink dramatically, technology companies with little stake in the health of publishing taking major roles and publishers faced with disintermediation and forced to build direct consumer relationships for the first time in their history

CPW’s European volume and revenue growth dropped in the December quarter, but this was largely due to the higher mix of prepay in the Christmas period, with underlying trends (strong contract, weak prepay) unchanged

US volume growth surged to 34% as the company continued to roll out standalone stores in malls and shopping centres, and there appears to be plenty of growth to come

Looking forward, the UK business is likely to suffer from the longer handset contracts that have been rolled out by the UK mobile operators over the last two years, but continued strength in the US is likely to more than make up for this

With the completion of digital switchover still on track for mid 2012, stabilisation of the main digital broadcast platforms is expected, with roughly equal numbers of subscription pay-TV and free TV homes, though with marked differences between the platforms in terms of demographic composition and the proportion of pay-TV customers

Further marked differences exist between the satellite, cable and terrestrial platforms with regard to PVR adoption, notably higher in pay-TV households where distribution can benefit from box subsidies and greater product consistency. National PVR penetration of TV homes is expected to grow from slightly below 50% in 2010 to over 70% in 2015

As DSO nears completion, the stage is set for broadband connectivity. Although household penetration of internet-enabled TV devices is expected to exceed 50% by 2015, the emergence of hybrid broadcast and broadband services is expected to proceed much more slowly, limited by a number of factors – not least the ability of service providers to monetise their non-linear on demand offerings

Google has launched a dedicated ebooks store in the US, with support from 4,000 publishers, providing an ecommerce platform for independent book retailers

Google’s aim is not revenue from ebooks, though the market is attractive: we estimate ebooks will be 5% of the US books market in 2010 ($1bn) and could grow to perhaps half of all book sales within the next five years

Like Amazon and Apple, Google is using ebooks to support its broader strategy, driving search traffic and building an ecommerce platform. Revenue from ebooks is less important than supporting these objectives

A large gap has opened up between the different platforms in the five years since HD launched in the UK, with the pay-TV platforms – above all Sky – gaining a large lead over the free-to-air satellite and terrestrial platforms

With HD Ready TV sets now counting for almost half the total population of TV sets in the UK, the big issue facing the free-to-air platforms is the number of channels, where Sky (now 52 HD channels) and Virgin Media (now 28 HD channels) are expanding their lead over the free-to-air platforms Freeview (now 4 channels) and Freesat (now 3 channels)

Freeview in particular offers no clear evolutionary pathway beyond five channels in the next five years, except through acquisition of more capacity in the coming spectrum auction, where the outcome is very uncertain or via streamed high capacity broadband, which faces significant challenges in building penetration
