What type of insurance marketing system primarily engages in direct sales to consumers through various media?

The direct response system is a type of insurance marketing system that focuses on reaching consumers directly through various media channels such as television, radio, print advertising, and online platforms. This approach allows insurance companies to market their products straight to the consumer without involving intermediaries like agents or brokers. The aim of this system is to generate leads and sell policies to consumers who respond to the marketing efforts, hence the term "direct response."

By utilizing direct sales, insurers can often streamline the purchasing process, allowing customers to obtain quotes, complete applications, and purchase policies easily and conveniently. This system is particularly effective for certain types of insurance products like auto or health insurance, where consumers are encouraged to take immediate action based on the advertisements they see.

In contrast, the other options involve varying levels of interaction with agents or brokers, leading to more traditional insurance marketing methods that do not rely primarily on direct consumer sales through mass media.
