Infomercials are long-format television commercials, typically five minutes or longer. Infomercials are also known as paid programming (or teleshopping in Europe). Originally, they were a phenomenon that started in the United States where they were typically shown overnight (usually 2:00 a.m. to 6:00 a.m.). Some television stations chose to air such programming as an alternative to the former practice of sign-off. By 2009, most US infomercial spending is during early morning, daytime, and evening hours. Stations in most countries around the world have instituted similar media structures.
