Clever companies know that there is big money in small pockets, which means that they're after your pocket money! And that's why they advertise everywhere, persuading you to buy their products with their smart slogans attractive colours and beautiful, smiling people. Some companies even send out ‘cool hunters’ to find out what young people find cool and then make adverts that appeal especially to them! Sometimes we need the things they are advertising, of course, but many times we really don’t.
