That means that customers can see them at any time and from any place. In cities, you can see them on the sides of buses, taxis and trains. There are advertisements high up on the sides of buildings. The names of famous brands, like Nike, Pepsi, Guess and Apple, appear on shoes, clothing and bags. So when people use these branded products in their daily life, they are helping the products to sell more of them. Every company gets you to recognize its name. The company name is always printed in the same way, using the same letters and the same colors. So, when customers see the same “look” of the company name day-in and day-out, they begin to recognize it without having to read it. We cannot predict the future of advertising, but one thing is certain- advertisements are here to stay and will always change the way of our life.
