Infomercials are advertising to a specific kind of demographic and are typically produced in a manner that mimics the format of entertainment programming. Synonyms for infomercials include advertisements, commercials, TV spots, product demos, and sales pitches. These types of adverts often employ persuasive techniques such as celebrity endorsements, testimonials, and statistics to convince viewers to purchase a product or service. Infomercials are often broadcast late at night or early in the morning when there are fewer viewers. This allows advertisers to buy airtime at a lower cost. While infomercials are often associated with lower-quality products, many reputable companies have successfully utilized this format to sell their products and services.
