The World: Washington - FTC forces US food- and drink-makers to help

The Federal Trade Commission, which is investigating marketing practices that are aimed at children, is ordering a range of food and drink manufacturers to provide it with information.

The Commission wants to examine not only the effects of TV, print and radio ads on children, but also the other ways in which the industry reaches them. This includes the internet, films and product placement in video games.

Deborah Platt Majoras, the chairman of the Commission, said: "We hope to get a more complete picture of marketing techniques for which publicly available data has so far been lacking."

Meanwhile, the Commission has criticised the entertainment industry for not doing more to adequately police the marketing of violent content towards children.
