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

AOL, Microsoft and Yahoo! are partnering to cross sell non-guaranteed display inventory in the US, highlighting their need for scale in the face of increasing competition from Google and Facebook

Aggregating unreserved ads via their respective networks may boost share of ad budgets, but the focus on less valuable inventory means any impact is likely to be small

Short of extending the partnership to include all inventory and greater investment in technology there seems little the three companies can do to stop further erosion of display share, though revenues should continue to rise

Nokia has launched its comeback with two very solid Windows Phone devices at €420 and €270. Next year Nokia, like Apple, will have handsets with uniquely appealing industrial design. However, Nokia will not launch in the USA until 2012 and needs to add cheaper smartphones to the portfolio

Nokia and Microsoft face a hard struggle in establishing a third mobile app ecosystem. However, it is not impossible (Google has managed it in 18 months) and given more devices and the right execution they could manage it

2012 will be the critical year. We believe that the flaws in the Android proposition mean there remains a real window of opportunity. However, if Apple launches a cut-price iPhone then the market will be turned upside-down, again

This presentation analyses the social games market in the UK. UK consumer spending on games software, like other recession-battered markets, has been flat for the last two years. At the same time, however, there has been rapid growth in PC-based social gaming, fuelled by the free to play nature of most games and viral marketing capabilities of social networks particularly Facebook. By 2015, we estimate that social gaming across PC, mobile and tablet devices could be worth up to £400 million, though much of this is likely to be driven by adding ‘social’ layers to existing games franchises.

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.

Internet advertising grew 15% YoY to €17.7 billion across Western and Central & Eastern Europe in 2010, according to provisional figures from IAB Europe

As in the US, growth in display, increasingly powered by social media, outpaced that of search, with display accounting for 33% of spend (up 3 ppts YoY)

We have updated our forecasts for 5 key markets – UK, Germany, France, Italy and Spain – and now project aggregated growth of 10% in 2011 and 13% in 2012

Facebook's audience and consumption growth is now generating substantial and rising display advertising revenue, with consensus estimates of $2 billion in 2010, up 160% YoY, and it will overtake Google on this count this year

The social network's growing position as the centre of the internet experience is enabling it to become a platform for other services, such as e-commerce, making it an increasing strategic threat to Google, as well as other players in the digital media

More importantly, like Google before it, Facebook’s scale and function has the power to disrupt the digital e-commerce and marketing models built over the past decade

Facebook Messaging adds email, IM and SMS to Facebook messages. Some portion of the social network’s 600+ million users will switch to Facebook for an all in one text-based communications service

Switchers to Facebook Messaging in the US will reduce the display ad revenues of traditional portals, like Yahoo! and Microsoft, which use such tools to drive traffic

Less affected is Google. Some Gmail users will switch, but Google’s core business model is selling search advertising, where it is not challenged by Facebook (yet)
