The Positive Effects of Advertising
Although people often focus on the negatives when they discuss the effects of advertising, it is important to note that advertising does have its positive side. In fact, some of our society’s most important messages have come through advertising, like “Friends don’t let friends drive drunk.” In addition to promoting important social messages, advertisements can also spark the economy by fostering competition and innovation.

Public Service Advertisements （公益广告的优点）
Public service advertisements are often the first things considered when people discuss the positives of advertisements. These advertisements market a social concept of importance to the general public. Many public service announcements run messages about health, safety and national security. In the United States, the Ad Council, a non-profit organization, sponsors many public service announcements. Their famous lines include “Loose lips sink ships,” a 1942 advertisement run to promote national security during World War II.（积累广告界的好例子） However, other non-profit organizations, the government, faith-based organizations and private companies also run public service marketing campaigns. For example, the U.S. government has run a number of advertisements about the importance of disaster preparedness.
Social Benefits （广告可以带来社会效益）
In addition to public service advertisements, traditional advertisements that market a product or service can offer social benefits. In fact, according to Megan VandeKerckhove, a student at the University of Florida’s Interactive Media Lab, advertising is free speech, and it can work to promote free speech. （广告可以鼓励言论自由）
According to VandeKerchkhove, this is especially true in countries where free speech has been suppressed. Advertising there, especially when it comes from the Western world where free speech is embraced, can encourage the idea that free speech is important. Furthermore, freedom of choice and advertising-supported entertainment, which is often a promoter of social change, are two important components of society that are both promoted through advertising.
Economic Benefits （广告可以带来经济效益）
Advertising has a number of positive effects on economies both in the U.S. and abroad. According to the International Advertising Association, advertising can encourage companies to compete and provide new products. This encourages more consumers to buy because these products meet the needs and wants of more consumers. Thus, the economy is positively affected. In addition, advertising can help create more jobs. As the demand for products and services goes up because of advertising, more people are needed to manufacture, supply, ship and test those products and services. Thus, more jobs are created. （广告可以促使竞争，可以制造更多就业机会，注意作者是如何论证的。）
In addition to encouraging consumers to choose the products that are best for them, advertising, at least in democratic nations, allows individuals to learn about the wide variety of lifestyle and political choices available to them and choose the ones that they find best. （主题句：营销广告的优点：让大家开阔眼界，知道有那么多东西可以供你选择）For example, in the United States, candidates for an elected position often run advertisements that discuss their strengths and the opponent’s weaknesses. These advertisements encourage Americans to compare and contrast the candidates and choose the one with whom they most agree.
The positive effects of advertising on modern society should never be underestimated.
