Appliant.com, the premier provider of customer-centric Web site management services, today announced a co-development relationship with RealNetworks(R), Inc. (Nasdaq:RNWK), the leader in streaming media delivery on the Internet. RealNetworks is using Appliant.com's performance management technology to monitor the activity and effectiveness of advertisements delivered by Real Broadcast Network (RBN), RealNetworks' Internet broadcast service.

This relationship and the resulting solution reveals the first of many initiatives that Appliant.com will launch to demonstrate its leadership position in the streaming media market.

"Appliant.com provides us with a great solution to help RBN's customers generate new revenue from their streaming media assets through RBN's leading advertising solutions," said Ian Freed, General Manager, RBN. "Through the integration of Appliant.com's technology, we are able to more effectively monitor the performance of our new advertising solutions."

As the first Web infrastructure management provider to break into the streaming media monitoring market, Appliant.com will deliver solutions to streaming media service providers like Real Broadcast Network that allow them to manage their systems from a customer-centric perspective. Appliant.com will debut this co-designed solution, which monitors the Advertising Extension for RealSystem to measure the usage of streaming advertisements, at The Real Conference 2000 in San Jose, May 22-26, 2000.

"After launching Lateral Line Network, our Web performance monitoring tool, customers and partners asked if we could develop a way to apply the same type of service offering to streaming media, which carries with it even more stringent performance requirements," said Brian Bershad, Ph.D., CEO and founder of Appliant.com. "We're fortunate to be able to work closely with companies like RealNetworks that have a clear understanding of these requirements. The solution we have provided to meet RealNetwork's monitoring demands reflects our customer-centric attitude and technical expertise. We will continue to evolve in this market, providing services to meet the needs of the more broadly defined streaming media market."
