Despite adverse economic conditions, spending on online advertising in the U.K. grew 4.2 percent year-over-year during 2009, according to the IAB U.K.’s biannual advertising expenditure report. The research – conducted on the IAB’s behalf by Pricewaterhouse Coopers – estimates that total spend reached £3.5 billion ($5.2 billion) in 2009, up from £3.5 billion ($5.1 billion) in 2008.
Unsurprisingly, paid search was one of the biggest growth drivers, as marketers concentrated on highly measurable channels throughout the year. Overall, the IAB estimates paid search grew 9.5 percent year-over-year, accounting for over 60 percent of all online ad spend.
