On 9 April Facebook bought the 547-day-old Instagram for about $1 billion in cash and shares, acquiring 40 million users, strengthening its positioning in mobile and photo sharing and preventing anyone else from buying it first

That Instagram could grow to be so big, so quickly, and with just 13 staff and $7 million of funding shows how precarious Facebook’s market leadership might still be. This is not a one-off – many more companies will use cloud services, mobile and social to achieve similar growth in future

This acquisition comes in the context of explosive growth in mobile and social and an accompanying land grab by Facebook, Amazon, Apple, Google and many others. More eye-catching deals are likely to follow

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

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

Iliad accelerated fixed line subscriber recruitment in 2011 thanks to a substantial increase in capital expenditure on its Révolution box, shrinking its cash flow margin

Iliad’s margin should recover somewhat in 2012 thanks to decreasing box prices. Fibre deployment is being scaled back due to weak demand

Mobile operating losses may be modest this year, but we expect pressure will build up in 2013 as network running costs rise and the termination rate asymmetry drops out

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

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

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

Facebook is winning the battle for eyeballs and advertising in the internet display arena, with revenues projected to reach $5.3 billion in 2012

By comparison, we expect Google to achieve revenue of $2.5 billion, after traffic acquisition costs, though it remains the king of internet advertising, due to its dominance of search

Increasing advertiser demand for scale and performance will make many publishers increasingly reliant on one or both of the internet giants for audience and revenue 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.
