B 　　China is likely to surpass the U.S. to become world’s largest online market this year, according to a recent report by market research firm iResearch. China’s online market generated revenue(总收入) of 20.8 billion yuan($3.04 billion) in 2008, up 52.2% over the previous year. Over 80% of the revenue came from big, multiplayer online s, with the rest generated from Web s and mobile s. 　　The overall market is expected to keep growing at an average annual rate of 20% in the coming five years. And iResearch forecasts that the Chinese online market will be worth more than 68 billion yuan by 2012, which will account for almost half of the global market by then. At present, U.S., China and Korea are the world’s top three largest online markets, up about 29%, 27% and 21% respectively of the global online market, according to the report. 　　U.S. companies derive a major part of their revenue from sales of s overseas. South Korea’s online industry generates half of its revenue from s in its home market. In China, however, most of the money comes directly from its own players. Negatively influenced by the global economic downturn, both the U.S. and Korea markets will see a drop in exporting, iResearch estimates. 　　In China, the enormous base and fast growing of online rs will further boost China’s online industry, said the report. China is currently home to 55.5 million online players, according to the latest stats by the China Internet Network Information Center(CNNIC).
