            Greenfield Online to Acquire OpinionSurveys.com Panel

    Ramps Greenfield Online U.S. Online Panel to Approximately 3.1 Million
Households, Approximately 8 Million People, and Creating One of the Industry's
                             Largest U.S. Panels

    WILTON, Conn., Aug. 19 /PRNewswire-FirstCall/ -- Greenfield Online, Inc.
(Nasdaq: SRVY), a leading provider of Internet survey solutions to marketing
research and consulting companies, today announced it has signed a definitive
agreement to acquire all of OpinionSurveys.com's online panel members from The
Dohring Company.  When completed, the acquisition is expected to add
approximately 1.1 million households to the Greenfield Online panel, bringing
Greenfield Online's total US-based Internet-only panel members to 3.1 million
households, with access to approximately 8 million individuals.  The all cash
transaction, which is expected to close by October, is subject to certain
closing conditions.

    Under the terms of the definitive agreement, Greenfield Online will
acquire specific assets from The Dohring Company, including the complete
OpinionSurveys.com panel, certain profile information contained in its
database; title to the domain names OpinionSurveys.com and OpinionSurvey.com;
as well as certain intellectual property and goodwill associated with the
OpinionSurveys.com panel.  Under the terms of the agreement, Greenfield Online
will not assume any liabilities from The Dohring Company.

    Dean Wiltse, Greenfield Online's President and Chief Executive Officer,
said, "This acquisition will give Greenfield Online one of the industry's
largest panels and will serve as a catalyst to further accelerate our
company's growth.  Our executive team identified OpinionSurveys.com because we
have admired the organization's panel recruitment and retention capabilities,
and we were impressed with the panel's activity metrics.  Importantly, our
panels are complementary with minimal overlap, and we already have the robust
technology infrastructure in place to absorb a panel of this size or greater.
Overall, this is an excellent opportunity for Greenfield Online and fully in
line with the growth strategy we outlined in our prospectus.  As a result, the
acquisition will significantly expand the size of our panel, and provide our
customers with an even broader offering of panel demographics."

    The Dohring Company was founded in 1986 and has operated
OpinionSurveys.com since 1999.  It has conducted more than 4,000 custom market
research studies for leaders in sports, entertainment and automotive
industries; financial and healthcare services; retail merchandising; as well
