Answer:
Advertisers use various principles of persuasion to influence consumers to buy their products. These principles include the Yale attitude change approach, elaboration likelihood model, central route, peripheral route, and foot-in-the-door technique.
One television commercial that uses these principles of persuasion is the Coca-Cola "Share a Coke" commercial. The commercial uses the central route of persuasion by appealing to the audience's sense of logic and reason. The commercial shows people sharing a Coke with their friends and family, and the message is that sharing a Coke brings people together. The commercial also uses the foot-in-the-door technique by encouraging people to personalize their Coke bottles with their names or the names of their loved ones. This technique is used to get people to buy more Coke products by starting with a small request and then building up to a larger one.
In conclusion, advertisers use various principles of persuasion to influence consumers to buy their products. These principles include appealing to emotions, logic, and reason, using social proof, authority, and scarcity, and using various techniques such as the foot-in-the-door technique. The Coca-Cola "Share a Coke" commercial is an example of how these principles and techniques are used in advertising to persuade consumers to buy a product.
