Seidman (communications, Ithaca College, New York) begins by reviewing trends in technology, social attitudes, legislation, advertising and political marketing, and other aspects. Then he focuses first on posters and broadsides in the US beginning in 1828, and the migration of campaigns to mass media beginning in 1932. His world tour takes in France, Britain, Africa, Latin America, and other locales. He concludes by assessing the effectiveness of posters and predicting future trends.
