Four eras in Communication Theory

Eras of Media Theory There are four main eras of media theory. The four eras are mass society, scientific perspective, limited effects and cultural criticism. Theories are constructed within media technology eras. These theories came about due to changes in society and politics. Era of Mass Society This era of theory started in the latter part of the 19th century. Media was seen as influential but negative. This era is characterized as a time in which people were worried about the power that media had to influence average people. People feared that media would ruin the value of society. Theories that came about during this time are : the propaganda theory and magic bullet theory. Propaganda is a method of communication that aims to influence attitudes and behaviors. Propaganda was used heavily in both World Wars and the Cold War. It has also been historically used in N.Korea and other communist nations. Adolf Hitler’s propaganda had the following characteristi

Theories and Paradigm of Development

The theories can be divided into two categories. 1. Unilinear world views of development. 2.Non-Unilinear world views of development In this section,' we shall discuss various development theories and paradigms. Over the years in many parts of the world, various developmental aims have been pursued by groups of people. We have seen, earlier in the unit, that the purpose of development is not one, neither is it uniform. For one nation, it may be to achieve total literacy, for some it may be drinking water, for other it may be building of motorable roads, for still others it may be reforestation. Depending on the aims, a certain process has been employed for development this process has been tried over and over again till it was refined. In other words, the process with its various trials became a theory. The development processes emanate from some philosophy. Therefore, a particular philosophy can have a group of developmental processes. In easy understanding, we might

Dance Model / Helical model of communication

Introduction In 1967, Frank Dance proposed the communication model called Dance’s Helix Model for a better communication process. The name helical comes from “Helix” which means an object having a three-dimensional shape like that of a wire wound uniformly around a cylinder or cone. He shows communication as a dynamic and non-linear process. Theory Dance’s model emphasized the difficulties of communication. Frank Dance uses the form of a Helix to describe communication process. He developed this theory based on a simple helix which gets bigger and bigger as it moves or grows. The main characterstic of helical model of communication is that it is evolutionary. Frank Dance explains the communication process based on this Helix structure and compares it with communication. In the Helix structure, the bottom or starting is very small then it’s gradually moves upward in a back and forth circular motion which form the bigger circle in the top and its still moves further.
