3, All kinds of advertisement (street billboards, catchy jingles on tvand radio, pictures in magazines and newspapers,..) try to attract our attention and introduce new products and ideas. I think advertisement is brainwashing. Advertisers make us believe we can realise our ambitions quickly and easily, only if we will use (of course, it means buy) their product. So, advertisers want us to spend money on their products.
But there are also advantages. Advertising is informative, increases demand, stimulates industry and keeps prices down.
When advertisers want to create successful advertisement, they use methods that help to sell new products:
-famous or well-known people promote certain products by saying that they use these products.
-average people in everyday situations are often shown using a certain product.
-advertising says that everybody buys a certain product.
-Advertising shows a very special idea, feeling, person or situation. It can transfer your good feelings to the product.
