Nielsen Online Completes the Media Rating Council Audit Phase Related to Its Patented Meter Technology and Editing

NEW YORK, NY, Oct 23 (MARKET WIRE) --
Nielsen Online, a service of The Nielsen Company, today announced that
the Media Rating Council's (MRC) independent CPAs have completed their
audit process covering NetSight, the company's patented meter technology.
The meter is currently in use in Nielsen Online's International panels
and its U.S. MegaPanel(R), and is now being implemented into the
company's audience measurement products in the U.S. This important phase
of the MRC's Internet audience measurement accreditation process covered
the full range of data collection functionality -- including data
capture, recording and transmission, post transmission data editing and
meter systems development processes.

Nielsen Online was the first Internet audience measurement service to
complete an MRC pre-audit, the first to enter the full accreditation
process and the first to complete this phase of the audit, which included
both the meter and editing process. The company is moving actively through
additional phases of the audit process, including audit committee review,
and helping to support the MRC's research related to several leading-edge
online measurement techniques used in Nielsen Online's products.
Additionally, Nielsen Online recently committed to a significant expansion
of the MRC audit process to include its Site- and VideoCensus products,
which combine, in addition to the NetSight meter, processes from Nielsen
Online's patented page-tagging technology and panel procedures.

"I'm pleased that the MRC audit committee now has information regarding
Nielsen's NetSight meter and processing systems," said George Ivie,
executive director of the MRC. "Nielsen Online is very engaged in the
audit process and making important progress, and we are happy with the
addition of Nielsen's census/hybrid products to the audit scope."

"Nielsen Online shares the industry's enthusiasm for quality, transparency
and accountability in Internet audience measurement, and we are delighted
to have completed this important step in the MRC process," said Mainak
Mazumdar, senior vice president, measurement science, Nielsen Online. "Our
NetSight meter collects -- in real-time -- Web sites visited, time spent
and pages viewed by Internet users, and is a critical component of
delivering accurate audience measurement data and insights to an
advertising market that now exceeds $20 billion annually in the U.S.
alone. We are proud of our team's work with the MRC and confident that our
investment in the process benefits advertisers, advertising agencies and
publishers who rely on independent, reliable measurement to support
planning, buying and selling efforts. We look forward to completing the
remaining components of the MRC audit and eventually receiving the
recognition of Accreditation."

Manish Bhatia, president, U.S. sales and global services, Nielsen Online,
added, "Concurrent with the MRC audit process, our extensive work with
clients around both panel- and site-centric audience measurement solutions
is driving clarity in the market. With integrated online video measurement
services and other data integration initiatives, Nielsen Online is in a
unique position to provide insights based on the industry's highest
quality research methods."

Nielsen Online's quality initiatives extend to international markets where
service reviews are also underway in Australia by the Australian IAB and
in France by the CESP (http://www.cesp.org/).

Nielsen Online also today announced it will be, for the second consecutive
year, the principal sponsor of the IAB (http://www.iab.net/) Audience
Measurement Leadership Forum, scheduled for Dec. 10, 2008 at the Roosevelt

Bhatia. "In addition to an ongoing dialog with clients and the market,
this annual event provides a great opportunity to assess our progress as
