Analysis of comScore data suggests that ad volumes fell in April on Facebook’s PC-based website in the US and UK, which we estimate account for 60% of ad revenue Seasonal effects may account for some of the decline, but increasing pressure on ad performance and pricing, due to the tough economic climate, and slowing growth in PC usage of Facebook are other probable factors As a result we expect Facebook’s ad revenue growth slowdown to continue in Q2, with audience saturation in key internet markets and increasing mobile substitution limiting future growth potential from display advertising

France’s sole cable operator, the smallest of the country’s five broadband providers, is sub-scale on the retail market and the heavy cost of servicing its debt leaves only meagre resources to leverage its superior network commercially

However, thanks to its white label deal with Bouygues, Numericable has resumed revenue growth and should achieve its 2014 debt/EBITDA target

As France Télécom’s network upgrade to fibre progresses, the main upside for Numericable lies in a closer alliance with Bouygues and possibly other DSL providers

According to IABUK/PwC, internet advertising grew 14.4% like-for-like in 2011 to £4.8 billion, overtaking press to become the single largest advertising medium

Search was again the main growth driver, surging 17.5% to £2.7 billion last year, while display rose 13.4% and classifieds increased just 5.2% on the weak economy

We now forecast internet advertising will increase 14% in 2012 and 12% in 2013, taking spend to £6.1 billion or 36% of UK advertising, up from 30% in 2011

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

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

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

The launch of the fourth mobile network operator in France has so far met with dramatic success, gaining around 1.5 million subscribers in the first month, driven by rock-bottom pricing and a clever mass media PR campaign

Its tariffs are, however, so low that it is very hard to see how they are sustainable in the longer term. In the short term, Free’s economics are boosted by asymmetric voice and text termination rates that result in other operators’ customers effectively subsidising Free subscribers by €5 to €10 a month

This arbitrage is very likely to disappear over the next two years, but Free Mobile can increase its prices when this occurs. Its challenge will be to acquire a critical mass of subscribers before this point, and to retain them thereafter
