Corporate Yahoo! and Citrix NFuse technology will be showcased at PC Expo in New York's Javits Center, Citrix's booth, number 3912, on June 27 through June 29, 2000.

"The convenience, efficiency and simplicity of accessing information via Corporate Yahoo! will improve the way enterprises work and communicate," said Barry Davis, vice president of corporate alliances, Citrix. "Our application-serving expertise, our NFuse application portal offering, and now our relationship with Yahoo! helps position Citrix as a leader in the application portal space."

"Corporate Yahoo! helps Global 2000 companies enhance their corporate intranets and extranets by providing a compelling service for accessing both corporate and personal information," said John Willcutts, vice president, Yahoo!

For the first time, end users can access and "subscribe" to interactive applications and content through a standard Web browser.
