Junk food advertising is “monopolising(垄断)” the Internet as television advertising comes under examination. Among 315 children’s websites, ads for soft drink, ice-cream, fast food and sugar are more than those for healthy foods by two to one.

Researchers looked at every food reference on 119 websites of companies active in advertising food and drink to children. They found that food references—anything from a picture or an article to an ad or a game—appeared on 44 per cent of popular children’s websites. Two-thirds of these were for unhealthy foods. Unhealthy products were three times more likely to be branded.

Many of the techniques used on food product websites for companies that included Cadbury, Nestle and Kellogg strengthen the food brand and make children spend more time seeing the product. More children spend more time on the Internet which captures and maintains children’s attention. It makes the Internet a powerful marketing medium.

Researchers found that 29 per cent of sites used advergames—in which the branded product is integrated (融入)into a computer game.The number of games per site varied. The Wrigley’s Candystand website contained 67   games. Those sites aiming at younger children and adults had a higher rate of advergames than those for preschool-age children, as did those sugary drinks , ice-cream and chocolate.

Kathy Chapman, the senior nutritionist at the Cancer Council, said, “The marketing is becoming a lot more complex. It used to be a couple of things; now it’s a whole range. The companies use different kinds of ways to promote their products and make them known. There’s a lot more things going on.”
