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

We forecast print media advertising will be down by about 4% in 2012, with national newspaper display roughly flat, performances we envisage will be seen as a temporary reprieve once the substantially tougher 2013 that we expect to follow is underway

Print media is not out of the structural woods, and even relatively small revenue contraction will amplify pain as the opportunities for further streamlining fixed-cost physical distribution operations are realistically diminishing

Digital is a greater challenge for paper than for screen media, as consumer and advertiser demand continues to weaken, yet publishers struggle to generate the killer service solution to stimulate scale revenue online

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

News International is to launch the Sun on Sunday on 26 February, seven months after closing the News of the World

In the intervening period, Trinity Mirror has picked up the bulk of the 55% of NoW copies that have not entirely fallen out of the market since June 2011

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

Enders Analysis co-hosted its annual conference, in conjunction with BNP Paribas and Deloitte, in London on 19 January 2012. The event featured talks by 13 of the most influential figures in media and telecoms, and was chaired by Sir Peter Bazalgette. An edited transcript of notes taken during the speaker presentations follows.

The speakers were Sir Martin Sorrell (CEO, WPP), Glen Moreno (Chairman, Pearson), Martin Morgan (CEO, DMGT), David Levin (CEO, UBM), Dan Cobley (MD, Google UK & Ireland), Mike Pocock (CEO, Yell), Vittorio Colao (CEO, Vodafone), Charles Dunstone (Chairman, Carphone Warehouse, TalkTalk Group), Stephen Carter (President, Alcatel-Lucent EMEA), the Rt. Hon. Jeremy Hunt MP (Secretary of State for Culture, Olympics, Media and Sport), Neil Berkett (CEO, Virgin Media), Liv Garfield (CEO, Openreach) and Ed Richards (CEO, Ofcom).

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

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

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
