SUNNYVALE, Calif. & TULSA, Okla.--(BUSINESS WIRE)--Oct. 2, 2000

iBEAM Broadcasting(R) Corp. (Nasdaq:IBEM), the leading global streaming media network (SMN), and Williams Communications Vyvx Services, the industry's leading video backhaul and advertising distribution services provider (NYSE:WCG), today announced an alliance that will allow the bundling of iBEAM's streaming media services and its Activecast(TM) solution with Williams' content collection capabilities to offer customers integrated streaming media solutions.

"Having the ability to offer Activecast Solutions in conjunction with our core products and services positions Vyvx as a single-source provider supporting our customer's transition to the new digital economy," said Laura Kenny, president of Williams Vyvx Services. "The Webcasting solution enabled by this alliance represents another ingredient in Vyvx's deployment of broadband media services and expands our ability to offer businesses one-to-many communication solutions to the Enterprise market. Vyvx's customers in the news broadcasting, sports, and entertainment industries are expanding the value of their media assets and brands. In support of this, Vyvx will leverage its extensive technological and video expertise to provide services which allow content owners to re-purpose video content for distribution to the Internet."

The agreement will expand web-based broadband media distribution capabilities for content owners interested in streaming media by combining two powerful technologies and the strengths of Williams Vyvx Services and iBEAM. By linking these two networks, content providers will receive a turnkey solution that supports both traditional video transmission requirements and streaming media needs.

"iBEAM has shown the value of its network in the entertainment world," said iBEAM president and CEO Peter Desnoes. "Now, iBEAM is teaming with companies such as Williams Vyvx Services to establish itself as the preferred streaming media solution for other forms of content. Sports, news events and entertainment -- these are the kind of events that are going to attract viewers to streaming media sites in greater numbers, keep them on the sites longer and keep them coming back for more. In addition, with more and more corporations looking to streaming media for communications solutions, this relationship will enable us to grow that side of our business."
