When communication is spread not just between two individuals but rather between tens of millions of people it is known as mass media.
Mass media is known as the central nervous system of society.
In order for mass media to exist, there must be an audience. Therefore, mass media exists in many different forms such as magazines, television, newspapers, internet, motion pictures, and even plays. Some examples of these forms of mass media are cosmopolitan magazine for young modern women and TSN television network for sports fans. With such extreme varieties of mass media existing in today's societies there are three major constraints that seem to have an impressionable impact. These constraints can keep mass media very restricted.
