New York - December, 5, 2005 - Behavioral targeting company WhenU (www.whenu.com) has debuted TrueRelevance™, a significant enhancement to WhenU Save, its permission-based desktop advertising software. A consumer that has WhenU Save with TrueRelevance™ installed who views a Web page describing a particular product or service for sale may instantly receive competitive offers from other merchants for the exact same product or service, saving both time and money. If the same consumer shops for airline tickets, TrueRelevance™ technology enables WhenU to offer instant, one-click access to other available flights to the consumer's chosen destination on the same date that may prove less expensive or more convenient.

"WhenU's implementation of TrueRelevance technology represents a powerful breakthrough in behavioral targeting," says WhenU CEO Bill Day. "We're helping consumers make smarter purchasing decisions on-the-fly while enabling marketers to reach consumers who are actively engaged in shopping for specific products or services. Most importantly, we're providing this functionality in a permission-based format that does not compromise the privacy, security or smooth functioning of the consumer's computer."

Day notes that early results in the travel category have been particularly promising, with click-through rates more than tripling from an already impressive average of 4% to 13.8% since the rollout of WhenU Save with TrueRelevance™ -- with no discernable drop in conversion rates.

WhenU's TrueRelevance™ technology examines the precise structure of a Web page offering a product or service for sale, including pricing and other detailed information, in order to give consumers instant access to comparative offers. To protect consumer privacy, the software does not use tracking cookies or transmit logs showing the consumer's Web browsing or purchasing history, nor does the software transmit the consumer's machine ID or collect any personally identifiable information or behavioral data.

WhenU Save with TrueRelevance™ is available for download at www.whenu.com, and is also available bundled for download with applications and content from WhenU's select group of distribution partners, who are able to offer their products to consumers free of charge because they are supported by advertising from WhenU.
