ROCHESTER, N.Y., OTTAWA, HONG KONG and SINGAPORE – August 16, 2007 – Continuing the expansion of its global research capabilities, Harris Interactive® (NASDAQ:HPOL) has acquired Decima Research, a leading Canadian research firm, and MarketShare, a private Asian research firm with co-located headquarters in Hong Kong and Singapore.

"Adding the strengths of these firms to the Harris Interactive enterprise will improve our global service offering and provide increased access into two fast-growing regions that represent about a $4 billion market opportunity," commented Gregory T. Novak, president and CEO of Harris Interactive. "We’re doing what we said we would do: grow this Company in order to remain competitive and serve our clients on a global basis," Novak continued. ‘"We believe that we’re going about it in the right way, by acquiring motivated partners who share our vision and by structuring future earn outs that align with our goals and promote mutual success."

"These acquisitions represent significant progress in extending our reach into the world’s top research markets. By adding these new operating units, Harris Interactive now has presence in six of the top ten research markets, and access to two-thirds of the global research market, up from approximately one-half just six months ago." stated Kyle Karnes, executive vice president of corporate development at Harris Interactive. "In line with our global expansion goals, we will continue to look for attractive partners in other sizable and high-growth regions around the world."

Named one of Canada’s 50 Best Managed Companies in each of the last two years, Decima Research is a privately-held, full-service, public opinion and market research firm headquartered in Ottawa, Ontario, Canada, with offices in Montreal, Toronto and Vancouver. The firm has particularly strong practices in financial services, telecommunications, public affairs and tourism/recreation/gaming research. Decima has approximately 125 full-time employees, and in FYE January 2007, generated US$26.2 million in revenue, about 20 percent of which was derived from online research. Combining the Harris Interactive Canadian online panel with Decima’s 140,000 online members will create one of the largest, best-managed and highest quality online survey panels in Canada.

"We’re thrilled to join Harris Interactive. This new union will allow us to utilize the technological muscle and extensive research solutions of Harris Interactive to better serve our clients," said Bruce Anderson, CEO of Decima Research. "I believe we will be able to quickly take advantage of many cross-border and global synergies to propel us to the next level of growth in the North American marketplace. For our employees, this transaction opens up great opportunities to do more, learn more and be even more successful."

Harris Interactive paid US$21.3 million in cash up front for the firm, plus future consideration tied to growth and profitability. The newly combined entity will be now known as Harris/Decima and join the Harris Interactive North America group. A complete transition to the Harris Interactive global brand will take place within the next year.

MarketShare is an Asia-Pacific consulting and market research firm with joint headquarters in Hong Kong and Singapore. The majority of their research is conducted in mainland China, Hong Kong, Taiwan, Japan, South Korea, India, Singapore and Malaysia. For the 12 month period ended June 30, 2007, the firm’s 40 employees generated approximately US$2.6 million in revenue (15% Internet-based) for about an 80 percent increase over the previous year.

As a member of the Harris Interactive Global Network, MarketShare has been working jointly with Harris Interactive on major global and regional accounts since 2004. The Company has proven expertise in the retail, financial services, technology and travel/tourism sectors.

"The rapid rise and continued growth of consumerism in Asia will force companies to better understand their customers’ evolving needs and drive demand for faster and more sophisticated research solutions such as those available through Harris Interactive," said Ali Mirza, executive director of MarketShare. "Harris Interactive with its global technology and experience, coupled with MarketShare’s localized knowledge and presence is a winning formula to tap these opportunities for rapid growth throughout Asia," added Anthony Venus, executive director of MarketShare.

Harris Interactive paid US$2.8 million in the all-cash deal for the firm plus future consideration tied to growth and profitability. MarketShare will become part of the Harris Interactive Asia group, and the transition to the Harris Interactive global brand is expected to begin immediately.

"I’m thrilled to welcome these two great organizations into the Harris Interactive family. Together, I believe that we will realize our vision of becoming a unified global research firm with the power to fully leverage our technology, our combined solution sets and the Internet to rapidly grow and achieve high levels of profitability," concluded Novak.
