History of advertising

The history of advertising can be traced to ancient civilizations. It became a major force in capitalist economies in the mid-19th century, based primarily on newspapers and magazines. In the 20th century, advertising grew rapidly with new technologies such as direct mail, radio, television, the internet and mobile devices.

Between 1919 and 2007 advertising averaged 2.2 percent of Gross Domestic Product in the United States.^{[citation needed]}
