Internet Advertising Revenues in Q3 ’08 at Nearly $5.9 Billion 11.20.08 11% Increase from Q3 ’07, Up Slightly from Q2 ’08 Despite U.S. Economic Woes NEW YORK, NY (November 20, 2008) — The Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers LLP (PwC) today announced that Internet advertising revenues reached almost $5.9 billion for the third quarter of 2008, representing an 11 percent increase over the same period in 2007. While double-digit annual growth continues, the quarter-to-quarter curve remains relatively flat compared to recent past performance. The Q3 2008 figures, published in the IAB Internet Advertising Revenue Report, are 2 percent higher than the Q2 2008 results. Set against strong economic headwinds in the U.S. economy, Q3 ’08’s $5.9 billion represents nonetheless the second-highest quarter results ever. For the first nine months of 2008, revenues totaled $17.3 billion, up from $15.2 billion in the same period a year ago and surpassing the record set in the first nine months of 2007 by nearly 14 percent. The growth of interactive advertising that we’ve been experiencing over the past few years has stabilized due in large part to the difficult current economic climate,” said Randall Rothenberg, President and CEO of the IAB. “Interactive advertising continues to be the most measurable and cost-effective way to reach consumers, and we see more and more marketers seeking to harness its power.” David Silverman, a partner at PricewaterhouseCoopers LLP, added that, “a weakening economy will continue to be a challenge to all forms of advertising-supported media. However, the Internet should be better poised to withstand the storm given its ability to combine performance-based advertising along with broad-based branding.” Conducted by the New Media Group of PricewaterhouseCoopers, the Internet Advertising Revenue Report was launched in 1996 by the IAB and aggregates data from all companies that report meaningful online advertising revenues.
