For the second quarter, Internet ad revenue was up 12.8% over the second quarter of 2007.
Search revenue continued to lead the way in the first half, totaling $5.1 billion, up 24.4% over the first half of last year.
Display advertising reached $3.8 billion in the first half, up 18.8% from the year-earlier period.
“Interactive advertising continues to demonstrate year-over-year growth as marketers and consumers increase their embrace of digital media,” said Randall Rothenberg, president-CEO of the IAB.
“Compared to the trajectory in other media and in the general economy, interactive has outperformed because it delivers a level of accountability unmatched by any other advertising medium.”
