Direct marketing is a form of advertising that reaches its audience without using traditional formal channels of advertising, such as TV, newspapers or radio. Businesses communicate straight to the consumer with advertising techniques such as fliers, catalogue distribution, promotional letters, and street advertising.Direct Advertising is a sub-discipline and type of marketing. There are two main definitional characteristics which distinguish it from other types of marketing. The first is that it sends its message directly to consumers, without the use of intervening commercial communication media.
