DRTV an acronym for Direct Response Television. It is a term that describes anything that is sold, either product or service, and typically is not something that is sold in stores. It can be a long form commercial that airs for 28 to 30 minutes or even up to 60. The long form infomercial is best for products that require demonstrations and explanation of the product. Short form can be either 30 seconds or 120 seconds. This form is best for products or services that require little time, but still want more time than a traditional advertisement. Because DRTV results can be tracked in real-time, it is a great way for a company to see the aftereffects of their marketing efforts.
