Google China served a market of mainland Chinese Internet users that was estimated in July 2009 to number 338 million, up from 45.8 million in June 2002. A China Internet Network Information Center (CNNIC) report published a year and a half earlier, on January 17, 2001, had estimated the mainland Chinese Internet user base at 22.5 million, considerably higher than the number published by Iamasia, a private Internet ratings company. The first CNNIC report, published on 10 October 1997, estimated the number of Chinese Internet users at fewer than 650 thousand people.
