Direct marketing:
Direct Response Marketing is designed to generate an immediate response from consumers, where each consumer response (and purchase) can be measured, and attributed to individual advertisements. This form of marketing is differentiated from other marketing approaches, primarily because there are no intermediaries such as retailers between the buyer and seller, and therefore the buyer must contact the seller directly to purchase products or services. Direct-response marketing is delivered through a wide variety of media, including DRTV, radio, mail, print advertising, telemarketing, catalogues, and the Internet.
