An infomercial is a long television advertisement dressed up to look like a normal programme. It often runs 15 or 30 minutes. A host talks to you as if this were a show, explains a product in great detail, shows demonstrations, and then tells you how to order. The name is a blend of information and commercial (an advert). You see them late at night, on shopping channels, and sometimes online as long product videos. Though actually, they are still adverts: the “information” is there to sell. The tone is often breathless and friendly, with phrases like “but wait, there’s more.” In American English the word is very common; in Taiwan the closest everyday hook is 電視購物, which is a close cousin even if the studio style is not always the same.
