Continues Trend of Record Setting Quarters

New York, NY (May 30, 2006) – The Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers (PwC)
today announced that Internet advertising revenues reached a new record of $3.9 billion for the first quarter of
2006. The 2006 first quarter revenues represent a 38 percent increase over Q1 2005 at $2.8 billion and a 6
percent increase over Q4 2005 total at $3.6 billion.

“The steady growth of online advertising is a clear indication that marketers continue to believe in the
opportunities and effectiveness that this medium delivers in reaching and engaging their consumers,” said
Greg Stuart, CEO, Interactive Advertising Bureau. “The Interactive Advertising industry remains committed to
the creation of a world class medium with best-of-breed standards, measurement guidelines, research and ad
products for marketers and agencies.”

“The Internet continues to shape the media landscape as more advertising dollars are going online,” said Peter
Petrusky, Director, Advisory Services, PricewaterhouseCoopers. “It is abundantly clear that marketers are
seeing a compelling opportunity to leverage the Internet as a powerful medium that drives both branding and
sales results.”

“Consumer habits are continuing to change and mature,” adds David Silverman, partner, Assurance,
PricewaterhouseCoopers. “Companies are effectively learning to devote more of their advertising budget to this
fast-growing advertising platform in order to reach the right audience at the right time.”

Conducted by the New Media Group of PricewaterhouseCoopers, the "Advertising Revenue Report" was
started by the IAB in 1996, and represents data from all companies that report meaningful online advertising
revenues. The results are considered the most accurate measurement of interactive advertising revenues
because the data is compiled directly from information supplied by companies selling advertising on the
Internet. The survey includes data concerning online advertising revenues from Web sites, commercial online
services, free e-mail providers, and all other companies selling online advertising. First and third quarter
revenue reports are estimates, with the actual figures being released along with second and fourth quarter data
respectively. PwC does not audit the information and provides no opinion or other form of assurance with
respect to the information.

The IAB sponsors the Internet Advertising Revenue Report, which is conducted independently by the New
Media Group of PricewaterhouseCoopers. The full report is issued twice yearly for full and half-year data, and
top-line quarterly estimates are issued for the first and third quarters.
