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

We have revised our central case forecasts of total year-on-year NAR (Net Advertising Revenue) growth in 2011 from 5% to 1%, as the advertising outlook has progressively worsened since mid April

2011 is marked by a further round of consolidation in airtime sales and a number of noteworthy channel and programming changes

Channel 4 Sales, and above all its flagship Channel 4, appears the most challenged of the leading market players, while we expect the ITV group to continue to outperform the NAR market in the rest of 2011 and 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

Q1 2011 TV NAR (Net Advertising Revenue) has delivered strong year-on-year growth of about 8%, yet the monthly variations are large, with a predictably sharp decrease in March based on past year comparatives countered by a large Christmas-style upswing in the Easter and Royal Wedding month of April

After several years of decoupling total display and TV advertising trends from those in the broader economy due to negative structural causes, the underlying positive correlations are expected to reappear as the structural factors subdue

The general economic outlook suggests stable growth in TV NAR during 2011 of about 5%, remaining flat to marginally positive in real terms beyond 2011 as long as conditions of weak economic growth last, but with significant risks of a sudden sharp downturn in the short to medium term
