Members of the Dutch political party GroenLinks canvassing door-to-door in Groningen
Door-to-door is a canvassing technique that is generally used for sales, marketing, advertising, evangelism or campaigning, in which the person or persons walk from the door of one house to the door of another, trying to sell or advertise a product or service to the general public or gather information. People who use this sales approach are often known as traveling salesmen, or by the archaic name drummer (someone who "drums up" business), and the technique is also sometimes called direct sales. A variant of this involves cold calling first, when another sales representative attempts to gain agreement that a salesperson should visit.
Historically, this was a major method of distributing goods outside large towns, with the salesmen, often self-employed known as pedlars or peddlers, also hawkers. With the huge growth of retail shops in the 19th century, it became less important, and the development of mail order and finally sales via the internet gradually reduced its significance in advanced economies except in a few fields, such as repairs and improvements to homes.
