In a recent market report, Frost & Sullivan praised ON24 for achieving the market leader position in the global virtual events market in 2008. According to the report, ON24 offers one of the industry's most comprehensive virtual event solutions, with a great deal of scalability and reliability, as well as a broad product portfolio, which includes self-service and assisted options.

She added that Frost & Sullivan believes that ON24's technology and market leadership in the virtual events market, its diverse line of webcasting and virtual event products and its sound financial standing will help the company maintain its leadership position going forward.

ON24 was cited for its relentless focus on quality and reliability and its constant innovation, as well as the successful launch last year of ON24 Virtual Show. "The market response to our growing product portfolio has been overwhelmingly positive, and this award acknowledges that," said Sharat Sharan, ON24 President and CEO. "We are experiencing unprecedented demand for our industry-leading webcasting and virtual event solutions. With more than 250 comprehensive, multifaceted virtual shows and 30,000 webcasts projected, 2009 will be our best year ever." The company's client base has grown significantly in the past year, and its footprint is especially strong in the global Fortune 500 segment, ON24's primary target market.

This strategy has worked well for ON24, which now owns over 30% of the market," said Alvarez.

In these economic times, having these options is critical for enterprises as they look to continue 'business as usual.'
