Question

You may think today’s cash rebate programs from car manufacturers are relatively new, but in 1914,
Henry Ford announced that if he sold 300, 000 Model Ts that year, each customer would receive a rebate. When the company reached its goal, Ford returned $50 to each buyer. This was good business. It also was good public relations. Like Henry Ford, public relations people today work to create favorable images— for corporations, public officials, products, schools, hospitals and associations.
There are three ways to encourage people to do what you want them to do: power, patronage and
persuasion. Power involves ruling by law, but it also can mean ruling by peer pressure—someone does something because his or her friends do. Patronage is a polite term for bribery—paying someone with favors or money to do what you want. The third method—persuasion—is the approach of public relations.
Persuasion is the act of using argument or reasoning to induce someone to do something.
Like advertising, the public relations business is not a mass medium. Public relations involves creating an understanding for, or goodwill toward, a company, a person, or a product.
