New York, NY (February 22, 2005) Today, the Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers (PwC) announced that Internet advertising totaled nearly $2.7 billion in the fourth quarter of 2004, the highest revenue quarter reported by the IAB. Estimates for the full-year 2004 totaled just under $9.6 billion – a 32% increase over full-year 2003 ($7.3 billion). Q4 2004 increased nearly 24% over Q4 2003 ($2.2 billion) and is approximately 17% higher than Q3 2004 ($2.3 billion). In November 2004, the IAB announced that the estimate for revenue in Q3 2004 was $2.4 billion. That figure has been revised to $2.3 billion. The IAB sponsors the Internet Ad Revenue Report, which is conducted independently by PwC.

The third and fourth quarter online ad revenue figure was estimated by surveying and aggregating 2004 fourth quarter data from the top 15 online ad sellers. The results were then extrapolated to calculate the total estimated industry revenue figure. Actual third and fourth quarter results will be reported in the full Internet Advertising Revenue Report, expected in Spring 2005.
