Classified advertising is a form of advertising that is particularly common in newspapers and other periodicals. A classified is usually textually based and can consist of as little as the type of item being sold, and a contact number to call for more information. It can also have much more detail, such as name to contact, address to contact or visit, a detailed description of the product or products. There are generally no pictures or other graphics within the advertisement, although sometimes a logo may be used.
