Advertisements do not merely sold products but it sells dreams and ideal ways of life. It sells and then reinforces time and again values those of consumerism and class consciousness. It also trades in stereotypes. Advertising creates and sustains an ideology of consumption. It is a social force affecting Indian homes today. Advertising is a social institution and a necessary social evil. The cost and benefit should be evaluated to determine the total impact of advertising on our social welfare the issue is not whether advertising is perfect but whether the benefits of advertising outweigh the costs making social welfare greater than advertising. Advertising is one of the functions of mass communication. All productivity relies on this medium of mass communication. Advertising diffuses information about commodities and markets them to persuade the common man of their place in his life. In fact advertising does more than this. It also plays a role in social change. It celebrates change and internalizes change for those who become better by using a certain product or service. In short advertising is the voice of technology because of that it represents the intention to affect life. Advertising though originally used to market products now seems to market feelings and sensations and styles of life. All this has been possible through an efficient communication network which has revolutionized changes. The first impact that one gets from the advertisement is that the viewers have no choice of their own in making preference for the consumer goods they want to use in daily life.
