BackWeb Announces Public Beta of Mac OS Client

Continues Commitment to Multi-Platform Support

SAN JOSE, Calif., (April 28,1997) -- BackWeb Technologies, a leading provider of Internet push broadcasting software, today announced the first beta version of its client for the Apple Mac OS. This version continues BackWeb's commitment to multi-platform support, by adding a client that was designed from the ground up specifically for the Mac OS platform.

"The new Mac OS client gives Mac users access to BackWeb's more than 50 content channels," said Eli Barkat, CEO of BackWeb Technologies. "It combines the Mac OS user interface with the unique delivery methods and bandwidth conservation methods offered in all the BackWeb Client versions."

BackWeb's Mac OS client is free, downloadable software for users that provides access to all BackWeb-enabled Internet or intranet broadcast channels. The BackWeb Client works in the background to download content or software from any channel to which the user is registered. The client allows users to set preferences for the kind of content received and when and how it should be displayed. The client user interface includes a menu bar icon that gives access to all features of the program and to content that is delivered through it to the Mac OS.

Users can also specify, during installation or anytime during use, whether BackWeb's Polite Agent™ or HTTP to communicate with channels will be used. BackWeb's ground-breaking, UDP-based Polite Agent delivery technology doubles Internet users' bandwidth by sending content during idle online time. HTTP is for users behind corporate firewalls who don't have access to communications that use the UDP protocol.
