I still have a few sentences to check.

Thank you very much, Writeacher.

1)When an ad tries to create direct contact with people, we can talk about interactive advertising.
2) For example, an important chain of supermarkets in the UK divides (has divided) its customers into social groups to help and understand them (coming up with a whole range of personalized products).
3) Interactive advertising are advertising techniques but they are more direct in their approach to their clients.
4) Advertising is dangerous for children because these haven’t got a strong will (?) yet; they just do what they see in ads without asking themselves if is right or wrong.
5) This magazine aims at defending us all against the might of the advertisers who just work for money and don’t worry if someone gets hurt because of them.
