Final answer:
The salesperson's call to inform about a new security system developed by Toyota to alleviate concerns about car theft exemplifies proactive marketing, where the company anticipates and addresses future problems before they occur.
Step-by-step explanation:
Six months after you bought your new Toyota car, the salesperson who sold it to you calls to inform you that Toyota has developed a car security system that should alleviate any concerns you might have about the car being stolen. This is an example of proactive marketing. Proactive marketing refers to a strategy where a company anticipates future problems, needs, or changes in the marketplace and addresses them before they happen. In this case, Toyota is not waiting for customer complaints or an increase in car thefts to address security concerns. Instead, they have developed a new security system in anticipation of such problems, and are actively reaching out to existing customers to inform them of the solution, hence demonstrating a proactive approach.
