China's Internet users reached 384 million by the end of 2009, more than the total population of the United States, according to the latest statistics released by the China Internet Network Information Center.

"Sixty percent of the Internet users here (China) are under the age of 30," Richard Ji, Internet analyst at Morgan Stanley, told

The New York Times

. "In the U.S., it's the other way around. And in the U.S., it's about information. But in China, the No. 1 priority is entertainment."

This presents a tremendous growth opportunity for Chinese online companies that are into gaming, news, content search and other online services. Massively multiplayer online role-playing game, or MMORPG, has grown at a rapid pace and revenue has witnessed compound annual growth rate of 100% over the last five years, yet it still remains an underpenetrated market.

IDC predicts that the China online gaming market will post a CAGR of 14.7% in the next five years and account for subscription revenue of RMB 50.8 billion ($7.5 billion) by 2014.
