A Coca-Cola television commercial featuring vivid animation of human organs - an eye ball, two tongues, a finger and a brain - has upset at least 178 people, who found it anything but fun. The animated tongues and other characters, which act and argue like human beings, were meant as part of a playful image in the recent ad for Coca-Cola Zero. But complaints made to the Broadcasting Authority said the commercial was disturbing, disgusting and also scared children. Three TVB viewers also told the station they found the ad disturbing. The broadcasting watchdog said it was investigating the complaints but had yet to draw any conclusion. The ad was produced overseas and aired in Hong Kong only, according to Coca-Cola China. Before airing the TV commercial, the company said, 200 people had been polled and 70 per cent said they enjoyed watching it. The company said it appreciated different views and that people had the right to form their own opinions on creative matters. Annisa Lee Lai Chun-hing, a Chinese University journalism professor, noted that the ad campaign was launched at the time when the celebrity sex-photos saga was at its peak - at the end of February. 'When people's minds are full of those images, they will find the two fleshy tongues disturbing,' she said. 'The disembodiment of body parts is very scary and vulgar, especially to children. In the United States, cartoon figures are proven to be able to arouse children's attention, so Coca-Cola cannot deny that the ad is for children.' She said it was understandable that the public would find the ad disgusting. The incident also exposed weaknesses in the government's advertisement monitoring system, especially on commercials targeting children under 18, she said. Although complaints had been made to the broadcasting watchdog, she said, the advertiser would not be affected. 'In fact, 178 complaints are very prominent for one commercial,' Professor Lee said. 'But by the time the authority finishes studying the case and passes its verdict, the advertising campaign will be over and the commercial will have been withdrawn anyway.' Coca-Cola China said the commercial finished its run on television last week.
