Tech sector IPOs surged by a factor of five in terms of value from 2008 to 2009. A mere $749.2 million raised in 2008 jumped to $3.8 million so far this year, according to data from Thomson Reuters. In 2008, only three went public, while 10 tech companies made the plunge in 2009. And, expectations are even higher for 2010.

Paul Bard, a research analyst at Renaissance Capital, forecasts between 40 and 50 tech industry IPOs next year, in which $4 billion to $5 billion in capital would be raised. "We've been expecting an uptick in technology because it has really been underrepresented in the market over the last few years," says Bard. The IPO market for high-tech companies was strong in 2007, but it seized up along with virtually every other form of capital raising when the financial crisis erupted in 2008.

It's a megatrend: the convergence of mobile devices and broadcast television. Keep in mind that worldwide sales of mobile phones hit 1.3 billion last year. Moreover, the growth should continue, especially in emerging markets in Asia, the Middle East, South America and even Africa. Thus, by delivering TV on mobile devices, the media industry can greatly expand its market.

But, there is a need for some critical technologies. And one of the leaders in the arena is Telegent Systems, which has filed to go public this week.
