Clearly if we are to participate in the society in which we live we must communicate with other people . A great deal of communication is performed on a person-to-person basis by the simple means of speech . If we travel in buses , buy thing in shops , or eat in restaurants , we are likely to have conversations where we give information or opinions , receive news or comment ,and very likely have our views challenged by other members of society . Face-to-face contact is by no means the only form. of communication and during the last two hundred years the art of mass communication has become one of the dominating factors of contemporary society .

No longer is the possession of information confined to a privileged minority . In the last century the wealthy man with his own library was indeed fortunate , but today there are public libraries . Forty years ago people used to flock to the cinema , but now far more people sit at home and turn on the TV to watch a programme the is being channeled into millions of homes .
