Moreover, Interactive advertising continues to prove itself as the most cost effective medium in driving sales and changing consumer attitudes providing a powerful competitive edge for these marketers. “The continued strength in Internet advertising reflects in part the medium’s unique ability to collapse the business cycle for advertising, marketing and branding, making it more attractive for traditional advertisers,” said Pete Petrusky, Director, Advisory Services, PricewaterhouseCoopers. “The high percentage growth in revenues is more significant given the larger revenue base.” David Silverman, Partner, Assurance Services, PricewaterhouseCoopers, adds, The third quarter figures are the most impressive weve seen yet.
