The IAB released its full year 2010 online advertising report this morning. Paid search constituted the largest category share of the $26 billion online ad spend, at 46 percent:
Search was down a point vs. 2009 in terms of overall share. However it grew 12 percent vs. last year in terms of dollar value. By comparison display advertising (a catch-all category that includes video, sponsorships and all types of graphical ads) saw 24 percent growth over 2009.
This year also marks the first time that the IAB and its partner PriceWaterhouseCoopers are estimating mobile ad revenues. They put US mobile ad revenues at between $550–$650 million in 2010. This is quite a bit lower than several other estimates in the market.
