Advertising plays a major role in the competitive business world. Many industries take advantage of the power of advertising to attract or to win customers away from their business competitors. The influence of advertising is so huge that it causes many people to buy things that they don't want at the start.

Advertising encourages people to buy things they don't want through misleading ideas. Advertising is proven to be a successful tool to stress the features of their product to the public even though it's regarded undesirable such as cigarettes，drugs，alcohol and so on. For example，Dunhill，a cigarette company which sponsors many football teams，seems to be promoting cigarettes to the public. Without the sponsorship，the company will be less known to the public，resulting in fewer sales of cigarettes.

Besides that，advertising has a large influence on the decisions made by the people in their everyday life. Many businesses use advertising as a form of promoting to create awareness about their product in the market. For instance，in a fast food industry，the introduction of a new flavor of burger needs advertising to reach the public while the other burgers require advertising to increase sales. Children，especially，are easily influenced by advertisements and will have the desire to dine at fast food restaurants after that. Although fast food is bad for health，it has successfully become appealing to the public through advertising.

However, advertising plays a part in helping customers to compare a product in terms of price, quality, reliability and so on. Without advertising, it will be very difficult for customers to judge the worthiness of a product. For example, advertisements published by various companies have given the customers the opportunity to choose wisely when they are purchasing an item. Without the power of advertising, customers will be stuck to a brand which may not offer the best choice.
