communication using technological devises share messages over great distances to influence large audiences. The technology of modern mass communication results from the confluence of many types of inventions and discoveries, some of which ( the printing press, for instance) actually preceded the Industrial Revolution.

Technological ingenuity of the 19th and 20th centuries has developed the newer means of mass communication, particularly broadcasting, without which the present near- global diffusion of printed words, pictures, and sounds would have been impossible. The steam printing press, radio, motion pictures, television, and sound recordings- as well as systems of mass production and distribution- were necessary before public communication, in its present form, might occur.

What I would like to discuss now is the actual process of mass communication and how it works. In mass communication, a professional communicator is the source, someone who shares information, ideas, or attitudes with someone else.

The source may be an author, a newspaper reporter, a television reporter, or an announcer.

The technological devices are the channels, or the means by which the message was sent Present age is called the age of information.And mass media are the powerful and the most effective instruments of spreading or sharing information..

An example of this would be that radio and television messages are transmitted via cable and satellite systems. The message is whatever the source attempts to share with another person.

In mass communication, the large audience comprises the receivers, the people who are the attended recipients of the message. Occasionally a receiver of the message will sent feedback to the source, that is, a response that allows the source to determine if the message was correctly understood.

In mass communication feedback can be conveyed through a letter to the editor, for instance, or a telephone call to a television station. Probably the most important is that by understanding the process of mass communication we will learn to think critically about the messages the media send us.
