NetRatings, Inc. has reached an agreement with Univision Online, Inc. the operator of the most visited Spanish-language Website in the United States (www.univision.com), to build an audience measurement panel to better understand Hispanic consumer behavior online.

The agreement between NetRatings and Univision will span a five-year period.

This agreement will result in a Hispanic Internet audience panel generated by industry accepted random digital dial (RDD) methodology. NetRatings will deploy its patented Internet measurement technology to a representative panel of 3,600 Hispanic individuals. The Hispanic sample will be folded into the current Nielsen//NetRatings panel, reflecting a representation of the entire U.S. Internet universe.

The Hispanic panel will provide the industry with a set of panel-based demographic information on Hispanic Internet users, providing vital intelligence for media buyers, planners, marketers and publishers targeting the fastest growing ethnic group online.

The service is expected to launch in the fourth quarter of 2003.
