In the UK, restrictions exist on ads that 'might result in harm to children physically, mentally or morally' and on ads employing methods that 'take advantage of the natural credulity and sense of loyalty of children'. Nor may advertisements 'exhort children to purchase or to ask their parents or others to make enquiries or purchases'. There are rules on food advertising, health, hygiene, safety and decency and there are restrictions on transmission time (for alcohol, medicines and slimming products) [Independent Television Commission, Rules on Advertisements to Children, 1997]. Greece has a ban on advertisements for children's toys between 7 am and 10 pm and a total ban on advertisement for war toys.
