Onstream Media and TSNN to Create Virtual Show for Tradeshow Industry Utilizing MarketPlace365T

POMPANO BEACH, FL – February 10, 2011 - Onstream Media Corporation ( OTC: ONSM), a leading online service provider of live and on-demand Internet broadcasting, corporate Web communications and virtual marketplace technology, today announced an agreement with Tarsus Advon for the Trade Show News Network (TSNN) to create a virtual tradeshow platform for the tradeshow industry - to be called the "Show of Shows" and powered by Onstream's MarketPlace365T.

TSNN expects the "Show of Shows" to be a virtual show environment at which some of the biggest live tradeshows in the U.S. will have an online presence, allowing buyers and exhibitors to interact 365 days a year and which will eventually feature thousands of tradeshow organizers and suppliers as exhibitors. This industry showcase, believed to be one-of-a-kind, is expected to enable the trade show industry to create an interactive forum and social community to provide TSNN's tradeshow organizers with a venue to attract new exhibitors and industry participants.

Another significant benefit for tradeshow organizers is that by participating in the TSNN "Show of Shows" they will have first hand experience in virtual tradeshow technology utilizing MarketPlace365. This provides them with the ability to extend their existing physical event, expanding their reach and creating new revenue opportunities.

"We have seen tremendous excitement about virtual events over the last year, and the buzz keeps increasing," said Stephen Nold, president of Tarsus Advon and founder of MeetingTechOnline. "This is why we've teamed up with Onstream Media to bring virtual event technology to our 21,000 U.S. tradeshow organizers and 2,000 industry suppliers. The virtual tradeshow drumbeat keeps getting louder and louder, and this event will give professionals the opportunity to experience one first hand without a major commitment of organization resources."

"We are excited that TSNN, which we believe is the industry's largest tradeshow network, has chosen us to help create this landmark showcase of virtual marketplace technology," said Randy Selman, president and CEO of Onstream Media. "We expect the show will build a strong sales pipeline for our new MarketPlace365 virtual tradeshow platform, which will serve as the backbone and engine for the 'Show of Shows'."

In addition to providing sales and marketing support and utilizing its extensive network of event-industry insiders, TSNN will help supply the show with dozens of industry speakers, bloggers, writers, thought leaders and subject matter experts. The "Show of Shows" virtual marketplace is expected to include a multitude of features, such as webcasting, pay-per-view content, chat rooms, file downloads, virtual breakout sessions and more.

MarketPlace365TM is a comprehensive, online lead-generation and communications virtual tradeshow platform that enables publishers, associations and tradeshow organizers to quickly, easily and affordably self-deploy and manage their own online multimedia "marketplace," while creating a compelling social media experience for the attendee. MarketPlace365 brings communities with common interests together online for commerce and information exchange. MarketPlace365 features include: social networking, search engine optimization, advanced analytics, videos, webinars, presentations and a full suite of marketing and communications tools.

The "Show of Shows" marketplace is planned to launch in March of this year and the product will be demonstrated at MTO Summit Chicago March 21-22 at the InterContinental Hotel in Rosemont.
