NEW YORK--(BUSINESS WIRE)--March 9, 2004

Adtag(TM) and Adcopy(TM) with Intellispot(R) Efficiently Deliver

Specific Messages to Specific Audiences

Comcast Spotlight, the advertising sales division of Comcast Cable, announced today that it will offer the segmentation products Adtag(TM) and Adcopy(TM) in Philadelphia, San Francisco, Boston, Dallas, Washington, D.C. and Atlanta. The rollout will be completed by the end of this month, allowing advertisers to target messages to almost 12.5 million cable subscribers in the top 10 DMAs. Adtag and Adcopy, already in use in Los Angeles, New York, Chicago, and Detroit, will be enhanced by IntelliSpot(R) software.

IntelliSpot, which was developed by Visible Word and Sea Change International, Inc., allows advertisers to easily tailor TV commercials so that they are relevant to certain segments of viewers, as opposed to a mass audience. Through the IntelliSpot toolkit, commercials are designed as individual media elements - i.e. video, audio, text, and graphics - with customization rules attached. The commercials then are reassembled into a variety of unique ads at or near the point of delivery. Advertisers can vary the elements and create ads with messages that are directly relevant to programming or geographic subsections of a market.

Adtag and Adcopy provide the infrastructure and operational support to deliver these variations quickly and efficiently to market subsections, using aggregate data for people residing within these areas. Customized ads can be telecast simultaneously to designated markets or zones without additional operator intervention. With these products, advertisers now have the capability to design, produce, and deliver a targeted television advertising campaign that broadcast TV cannot offer.

"The ability to better reach a receptive audience with strong message retention across multiple networks, with a single buy, is an extraordinary benefit to advertisers and unique to cable," said Hank Oster, Senior Vice President of Comcast Spotlight. "Advertisers can tailor the mix of commercials to deliver messaging that is most relevant to their desired audience, without sacrificing the broad reach needed to build a brand across an entire market."

Key categories expected to benefit from running commercials with tags that are specific to market subsections, or running different copy in different market subsections, include automotive, retail, and political. Multi-cultural marketing is made easier, too, since spots in numerous languages can be sent simultaneously within a market.

"This partnership extends the targeting advantage of cable and boosts efficiencies of media buys by allowing spots to be quickly, easily and cost-effectively updated or modified," said Seth Haberman, CEO of Visible World. "Since media budgets work harder when exposure is targeted, these new options enhance return on investment."
