MOST people are unhappy with the amount of sex, violence, nudity and triad activities shown on television. The Broadcasting Authority's latest survey showed viewers thought quality had fallen in every category of show except news. Compared with the last survey in 1990, four times as many viewers thought the quality of drama series was low; three times as many thought the same about children's programmes; and a staggering eight times as many thought cultural and arts programmes were poor. But about 55 per cent rated news and current affairs programmes highly. Nearly two-thirds of the 2,000 people surveyed did not like the portrayal of triads, compared with about a third in the 1990 survey. On April 1, the code of practice was changed to state exactly what triad activities could be shown. Legislator and recreation and culture panel vice-chairman Man Sai-cheong said the panel was looking at what conditions, if any, could be added to the companies' licences, which come up for their mid-term review next month. The secretary and assistant commissioner of the Television and Entertainment Licensing Authority, David Webb, said suspension of the companies' licences was unlikely. He said the public could best show displeasure by switching off. The authority will meet the main television companies - TVB and ATV - next week. Ninety per cent of respondents said they watched TVB the most, seven per cent ATV Home and two per cent TVB Pearl. Jeffrey Chan Wing-hung, senior programme manager (operations) at ATV, put a brave face on the findings, saying: ''We welcome the Broadcasting Authority having conducted the survey and giving us a chance to better understand what the public wants. TVB's Lily Chan Chu-kiu said the company would not want to see creativity hampered due to over-regulation or censorship.
