IAB/PwC RELEASE FIRST QUARTER 2005 INTERNET AD REVENUES FIGURES 06.06.05 FIRST QUARTER 2005 HIGHEST INTERNET AD REVENUE IN NINE CONSECUTIVE GROWTH QUARTERS $2.8 Billion Q1 2005 is 26% over Q1 2004 New York, NY (June 6, 2005) The Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers (PwC) today announced that Internet advertising totaled over $2.8 billion for the first quarter of 2005 making this the highest reported quarter in nine consecutive growth quarters. Q1 2005 revenues represent a 26 percent increase over Q1 2004 ($2.2 billion) and a 4.3% increase over Q4 2004 ($2.7 billion.) Marketers continue to recognize the relevance of interactive as an integral part of their marketing mix, said Greg Stuart, president and CEO of the IAB. The continued and steady growth we have experienced over the past 2 years is a clear indication that this medium delivers results and is fast becoming accepted as part of the mainstream. While the online audience gets bigger and broader, the TV audience continues to fragment, even as the cost of advertising spots rises, notes Tom Hyland, Partner and New Media Group Chair, PricewaterhouseCoopers. Add the growth of broadband in the home, which enables advertisers a platform to deliver rich media, and brand advertisers have a new mass audience to target. The economics are too compelling for marketers to ignore. The IAB sponsors the Internet Advertising Revenue Report, which is conducted independently by the New Media Group of PwC. The full report is issued twice yearly for full and half-year data, and top-line quarterly figures are issued for the first and third quarters.
