Advertising can have both negative and positive effects. Consumers may be convinced to buy a product
of poor quality on high price because of an advertisement. For example, some advertisers have appealed to
(迎合) people's desire for better fuel economy for their cars by advertising automotive products that improve
gasoline mileage (英里数). Some of the products work. Others are worthless and a waste of consumers'
money.
Sometimes advertising is misleading on purpose. A few years ago a brand of bread was offered to dieters
(节食者) with the message that there were fewer calories (热量单位, 大卡) in every slice. It turned out that
the bread was not dietetic (适合于节食的). But there were the same number of calories in every loaf.
On the positive side, Advertising may sometimes respond to a consumer's real needs. Consider fire
insurance (保险). Fire insurance may be sold by appealing to fear of loss. But fear of loss is the real reason
for fire insurance. The security of knowing that property is protected by insurance makes the buy of fire
insurance a worthwhile investment (投资) for most people. If consumers consider the quality of the insurance
plans as well as the message in the ads, they will benefit from the advertising.
Each consumer must be clear about her or his own situation. Are the benefits of the product important
enough to justify buying it? Advertising is intended to appeal to consumers, but it does not force them to buy
the product. Consumers still control the final buying decision.
