Two step flow theory — La théorie nommée « Two step flow theory » a été développée par Paul Lazarsfeld (avec Bernard Berelson et Hazel Gaudet) après la Seconde Guerre mondiale, aux États Unis, dans son livre The People s Choice (1944). Il s agit d une analyse … Wikipédia en Français
Two-step flow of communication — The two step flow model was propounded by Paul Lazarsfeld and Elihu Katz. Unlike the hypodermic needle model which considers mass media effects to be direct, the two step flow model stresses human agency. According to Lazarsfeld and Katz, mass… … Wikipedia
