During the first six months of 2007, online ad revenues grew by 26.4 percent over the same period last year to nearly $10 billion, according to the latest report from the Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers (PwC).
According to ClickZ News:
Little has changed in the distribution of revenues across search, display and other channels. Search spending during the year's first half accounted for 41 percent of all revenues, compared with 40 percent for the year-ago period. In raw dollar terms, search grew 29 percent to $4.1 billion. Display advertising meanwhile increased from $2.4 billion, or 31 percent of the pie, in the first half of 2006, to $3.2 billion, or 32 percent, for the 2007 period.
