Direct marketing is a form of communicating an offer, where organizations communicate directly to a pre-selected customer and supply a method for a direct response. Among practitioners, it is also known as direct response marketing. In contrast to direct marketing, advertising is more of a mass-message nature.

An infomercial is a form of television commercial that resembles regular TV programming yet is intended to promote or sell a product, service or idea. It generally includes a toll-free telephone number or website. Most often used as a form of direct response television (DRTV), they are often program-length commercials, and are typically 28:30 or 58:30 minutes in length. Infomercials are also known as paid programming. This phenomenon started in the United States, where infomercials were typically shown overnight, outside peak prime time hours for commercial broadcasters. Some television stations chose to air infomercials as an alternative to the former practice of signing off, while other channels air infomercials 24 hours a day. Some stations also choose to air infomercials during the daytime hours, mostly on weekends, to fill in for unscheduled network or syndicated programming. By 2009, most infomercial spending in the U.S. occurred outside of the traditional overnight hours. Stations in most countries around the world have instituted similar media structures. The infomercial industry is worth over $200 billion.
