Q3 2004 Interactive Advertising Revenues Total Over $2.4 Billion Fourth Record-Setting Quarter 11.15.04 NEW YORK, NY (November 15, 2004) Today, the Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers (PwC) announced that Internet advertising totaled approximately $2.43 billion in the third quarter of 2004 – the eighth consecutive quarterly increase for the industry and the fourth record-setting quarter. Q3 2004 represents a 35.3% increase over Q3 2003 ($1.79 billion) and a 2.4% increase over Q2 2004 ($2.37 billion.) The IAB sponsors the Internet Ad Revenue Report, which is conducted independently by PwC. The third-quarter online ad revenue figure was estimated by surveying and aggregating 2004 third-quarter data from the top 15 online ad sellers. The results were then extrapolated to calculate the total estimated industry revenue figure. Actual third quarter results will be reported along with actual fourth quarter revenues in the full Internet Advertising Revenue Report, expected in Spring 2005. “Historically, the second and fourth quarters are the strongest in advertising,” said Greg Stuart, president and CEO, IAB. “That the industry bested 2Q revenues is testament to the confidence and success marketers have found in the medium. As the experts predict, the Holiday season should be a merry one for the industry.” “Single digit, sequential growth demonstrates the industry has left behind the large revenue spikes that characterized the early years. We’re now looking at a maturing, stable industry that inspires further investment by large, traditional marketers,” said Tom Hyland, Partner and Chair, New Media Group, PricewaterhouseCoopers. “Revenue results for the first nine months of 2004 totaled slightly over $7.0 billion versus the $7.3 billion reported for all of 2003. Based on historical revenue results, 2004 is shaping up to be a record year, possibly exceeding by a large margin the previous revenue record reported in 2000 of $8.0 billion,” said Pete Petrusky, Director, Advisory Services, PricewaterhouseCoopers.
