Gaithersburg, MD - January 23, 2003 - WeatherBug has unveiled an innovative "On-Demand" online advertising model that enables its 17 million users to change their sponsor at will. The capability debuted with the launch of WeatherBug 5.0, a significant upgrade to the Internet application that is now available at www.weatherbug.com.

WeatherBug is the number one source of weather information on the Web and one of the top news and information sites, according to comScore Media Metrix, an Internet audience measurement firm. The free, ad-supported Internet application streams live neighborhood weather conditions, severe weather warnings, civil emergency alerts and forecasts to more than 17 million PC users. It is powered by AWS Convergence Technologies' nationwide network of 6,000 weather stations, which is based mostly at schools. AWS owns and operates WeatherBug.

With the launch of version 5.0, WeatherBug now features a "Choose Another Sponsor" button that enables a user to change their sponsor as often as they would like. Once clicked, WeatherBug presents consumers with a list of advertisers to choose from, divided into several major categories such as health, travel, computing, education and others.

When a new advertiser is selected, WeatherBug's appearance changes to display the advertiser's messages wrapped around the weather content in a unique format called BrandWrap™. This WeatherBug online advertising paradigm, which enables high brand recall, first debuted in 2001. Users also receive a welcome email from their new advertiser and are shuttled to the sponsor's Web site during the selection process. Advertisers participating in this program only pay for sponsorships when their ads are chosen.

"This immersive On-Demand advertising experience benefits both advertisers and consumers. Advertisers are guaranteed to reach consumers that are highly interested in what they have to say through three channels, while consumers get to hear from only those advertisers they are interested in," said Andy Jedynak, WeatherBug's Senior Vice President, General Manager.

WeatherBug's new "Advertising On-Demand" feature is an expansion of the highly successful program called Sponsor Select™ that debuted last year. Sponsor Select enables consumers to have more control over who advertises to them.
