THE TWO-STEP FLOW MODEL OF COMMUNICATION INTRODUCTION The two-step flow of communication hypothesis was first formulated by → Paul F. Lazarsfeld and his colleagues in their classical study on the 1940 American presidential election (1944). It states that there is usually no direct influence of the mass media on the general public. Rather‚ “ideas often flow from radio and print to the opinion leaders and from them to the less active sections of the population” (Lazarsfeld 1944). This assumption

result from energy flow into a system (heating by electrical power‚ contact to thermal bath‚ absorption of radiation‚ e.g. microwaves‚ sun radiation etc) and/or energy flow from a system to the surrounding. The former leads to heating‚ whereas the latter results in cooling of an object. The cooling of objects is usually considered to be due to three fundamental mechanisms: conduction of heat‚ convection and radiative transfer of energy . Although these three mechanisms of energy flow are quite different
