Chinese people are now spending more time surfing the net than watching TV, according to results of a survey by the Chinese Academy of Social Sciences (CASS) published Thursday.

The survey, of citizens of five Chinese cities, found that 79 percent of interviewees use the internet for information, and 55.1 percent to read news on the internet. About 63 percent of the interviewees use e-mail. The average times spent surfing the net and watching TV were 2.73 hours and 1.29hours, respectively.

Only 10.4 percent reported use the internet primarily to send and receive email; 65.9 percent read online news; 62.2 quite often play games on-line. More and more people have taken an interest in the entertainment opportunities online. Up to 56.5 percent of interviewees quite often download music, and 53.5 percent get entertainment messages from the internet.
