Major brands (such as Apple,) have used infomercials for their ability to communicate more complicated and in-depth product stories.

This practice started in the early 1990s and has increased since.

The book As Seen on TV (Quirk Books) by Lou Harry and Sam Stall highlights the history of products such as the Flowbee, the Chia Pet and Ginsu knives.

Sometimes, traditional infomercials use limited-time offers or claim one can only purchase the wares from television to add pressure for viewers to buy their products.

Many products and services that advertise using infomercials often also use these shorter spots to advertise during regular programming.

Many traditional infomercial producers make use of flashy catchphrases, repeat basic ideas or employ scientist-like characters or celebrities as guests or hosts in their ad.

When used this way, the term may be meant to carry an implication that the party making the communication is exaggerating truths or hiding important facts.

Often, it is unclear whether the actual presentation fits this definition because the term is used in an attempt to discredit the presentation.

An infomercial is a form of television commercial, which generally includes a toll-free telephone number or website.

Most often used as a form of direct response television (DRTV), long-form infomercials are typically or minutes in length.

The products frequently marketed through infomercials at the national level include cleaning products, appliances, food-preparation devices, dietary supplements, alternative health aids, memory-improvement courses, books, compilation albums, videos of numerous genres, real estate investment strategies, beauty supplies, baldness remedies, sexual-enhancement supplements, weight-loss programs and products, personal fitness devices, home exercise machines and adult chat lines.
