“The torrid growth of interactive advertising revenue persists and these results are really no surprise but very welcome news,” said Randall Rothenberg, president and CEO of the Interactive Advertising Bureau. “More and more marketers have embraced the reality that interactive is the fulcrum on which their brand strategies need to be based and we expect robust growth to continue.”

“The first six months of 2007 has continued the trend over the past several years of strong sequential growth,” said David Silverman, partner, Entertainment, Media & Communications Practice, PricewaterhouseCoopers. “The growth, which was led by strong increases in the consumer advertising sector, continues to point to the mainstream acceptance of the medium and advertisers’ continuing reliance on it.”
