Los Angeles, CA - September 12, 2006 - Roundbox, a leader in mobile broadcast software, announced today that the company has been awarded the 2006 Frost & Sullivan Entrepreneurial Company Award for the U.S. Mobile Video Services Markets. As one of the early leaders in the mobile broadcast market, Roundbox has proven its ability to capitalize and adapt to a growing market with its compelling infrastructure and applications.

This award is presented each year by Frost & Sullivan to the company that demonstrates superior entrepreneurial ability as well as offers a unique and revolutionary product solution with significant market potential.

Roundbox has developed an innovative end-to-end suite of mobile broadcasting solutions that are expected to be a key enabler in the U.S. mobile broadcast industry, said Vikrant Gandhi, mobile communications industry analyst for Frost & Sullivan. Recognizing the company's approach and entrepreneurial capabilities, we expect Roundbox to play a central role in this market both in the U.S. and internationally.

We are honored that we have been recognized by Frost & Sullivan for our capabilities and visionary approach, said Dennis Specht, founder and CEO of Roundbox. This award reinforces our bold vision for mobile broadcast and our passion to deliver innovative and superior products and solutions to our customers and partners.

Frost & Sullivan expects the total market revenues of mobile broadcast to exceed $1.5 billion by 2010 in application revenues alone and when combined with other subscription charges, they project the market will be much bigger. Gandhi continues, Mobile broadcast networks offer several advantages over the traditional unicast networks, and it is up to technology leaders such as Roundbox to educate the industry, show real products that leverage these next-generation capabilities and more importantly, assist the value-chain participants in revenue generation and hence prove the business viability. We believe Roundbox has the momentum to deliver on its vision.
