the advertising effect

I think most of the people may know a specialized term which is called the "advertising effect". In the modern society, advertisement is become an indispensible part of our life, we can see a lot of advertisements everywhere in the daily life, like the TV, computer, website, market, even on the streets in every corners. When I realized this, I cannot image what our life gonna be if the advertisements disappeared in our life. People usually prefer to buy some goods if it is well known in that field. A good advertisement can show people the quality, purpose and other uses of a good, peoples' mind were controled by the embellish of the advertising, so we called this "advertising effect". My professor showed us a lot of videos on the advertising class, I really love this course and find it interesting, the slogan and image will give customers a lot of  imaginary spaces to find and understand what the designers gonna show to the customers.
