The Two-Step Flow of Communication is an important theory in communication and advertising that explains how mass media messages influence people indirectly through opinion leaders rather than directly affecting all individuals.
This theory was proposed by Paul F. Lazarsfeld, Bernard Berelson, and Hazel Gaudet in the 1940s during a study of voting behaviour.
