Infomercials, also known as Direct Response TV (DRTV), are television commercials which generally include a phone number or website. There are long-form infomercials, which are typically between 15 and 30 minutes in length, and short-form infomercials, which are typically 30 seconds to 120 seconds in length. Infomercials are also known as paid programming (or teleshopping in Europe).
