Hong Kong Web surfers are among the most avid consumers of Internet porn in Asia, with 40 per cent of people who went online last month visiting an adult site. More than 420,000 people surfed the Net for porn that month, spending on average more than one hour online, according to Web assessment firm NetValue. Only Koreans managed a higher rate at 56 per cent. Singapore (36 per cent), Taiwan (35 per cent) and China (26 per cent) were all decidedly more conservative in their Web browsing habits. Hong Kong outpaced all the European nations polled in the survey, with only Spain reaching the same level. 'It was shocking to see we are even higher than Germany where they have much more liberal media laws,' said Shelley Yip, group public relations manager for NetValue. Women comprised 30 per cent of the Hong Kong visitors to adult sites, which were defined as anything that contains images, writing or other content that is obscene, indecent, sexually explicit, violent or repulsive. Men tended to linger longer when viewing porn, spending an average of 78 minutes at adult sites, compared with just under 50 minutes for women. People aged 50 and over were numerically the smallest group of visitors - only two per cent of the total - but it took them longer to find what they were looking for. Students and white-collar workers were the most frequent viewers of online porn in Hong Kong. As people's salaries increased, the likelihood of them visiting adult sites decreased. Those earning $65,000 or more a month accounted for only one per cent of visitors.
