Infomercial

n. television or radio commercial which advertises a particular product while giving helpful information or tips that incorporate the advertised product

Infomercials are television commercials that run as long as a typical television program (roughly 28 minutes, 30 seconds). Infomercials, also known as paid programming (or teleshopping in Europe), are normally shown outside of peak hours, such as daytime or late night (usually 2:00am to 6:00am). There are many people who claim to have started the modern infomercial business. The word infomercial is a portmanteau of the words "information" and "commercial". As in any other form of advertisement, the content is a commercial message designed to represent the viewpoints and to serve the interest of the sponsor. Infomercials are often made to closely resemble actual television programming, usually talk shows, with minimal acknowledgement that the program is actually an advertisement.
