UK advertising spend increased 3.8% year-on-year in the second quarter, exceeding earlier forecasts by 0.9 percentage points, with growth driven by the Jubilee and Euro 2012, as well as advertisers moving budgets forward for the Olympics, according to the latest Advertising Association/Warc Expenditure Report. Ads on cinema led with a 23.9% increase, ahead of online (14.8%), radio (9.4%), TV (4.4%) and out-of-home, which got a pre-Olympics boost of 9.9%.
