An infomercial is a long-format television commercial, typically five minutes or longer. The word "infomercial" is a portmanteau of the words "information" and "commercial". The main objective in an infomercial is to create an impulse purchase, so that the target sees the presentation and then immediately buys the product through the advertised toll-free telephone number or website. Infomercials describe, display, and often demonstrate products and their features, and commonly have testimonials from customers and industry professionals.[citation needed]
