MC is a process by which a message starting from one place reaches a large number of people in many different places. The situation is different than usual face-to-face communication in a small meeting, classroom or boardroom. MC is not possible in the opposite direction, i.e. from recipient to source. Communication technology grew effectively and limitlessly in the 20th century, resulting in many astounding advances in this field. The invention of the computer and, subsequently, of the Internet has revolutionized the role of communication in modern life to such an extent that even a school student of today's age feels disoriented if he is forced to live in an environment far from TV and the Internet. The possibility of communication in reverse – from recipient to sender – is now possible thanks to advances in technology. There are three basic means or media of mass communication. These are...a. through the printed word or image, in the form of newspapers, books, magazines and advertisementsb. through the medium of sound: radio, tape recordings and records including audio CDs and cassettes. through a combination of sound and image as in television, DVDs, CDs, computers and the Internet. The medium that has practically exploded in the world is television. Computers and the Internet have supported the popularity and reach of TV. The use of the Internet has been so intense that it is beginning to eclipse printed newspapers, books and magazines. Cassettes, a product of new age technology, have also become obsolete. CDs replace DVDs and the improvement in technology continues. Traditional letters, circulars, flyers and posters are on the way out as the use of the Internet has given rise to emails. At n... middle of paper... society and government keep them in check. Political persuasion through captive TV and newspapers has failed entirely to convert people with different views to the side of their masters. Studies conducted by renowned social scientists have shown that aggressive propagation of a certain political view often leads to each other's viewers clinging to their opinions. This is why Fox News fails to convert Democrats to the Republican Party. Propaganda by interested groups is not necessarily corruptive in nature. For example, advertisements on Indian television that highlight the importance of female education or nutrition for a pregnant woman convey very relevant and benevolent messages. In developing countries we often see advertisements against smoking and alcohol. Prejudices in Indian society can be overcome through mass communication.
