Online advertising spending growth in the UK is well ahead of the US and other developed nations, and it is forecast to account for more than half of all online ad spending in Western Europe in 2010 with a 52.6 percent market share, according to eMarketer, writes MarketingCharts.

Steady economic growth, further advances in broadband, mobile Internet access and associated ad-serving technology, will help fuel this growth, according to eMarketer's "UK Online Advertising" report.
Coming off 47 percent year-over-year growth in 2006, online ad spending in the UK will rise from 2.6 billion pounds in 2007 (31 percent more than the 2.02 billion pounds in 2006) to 4.5 billion pounds in 2011, eMarketer forecasts.

Online advertising is expected to account for 18 percent of all UK advertising spending in 2007 - more than double the percentage for other European countries and the US.

The continuing shift of substantial advertising budgets to digital platforms will see online ad spending grow 31 percent in 2007 and more than 10 percent per year for the rest of the decade, eMarketer said.
