Clearly if we are to participate in the society in which we live, we must communicate with other people. A great deal of communicating is performed on a person-to-person basis by the simple means of speech. If we travel in buses, buy things 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 to 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. Two things, above others, have caused the enormous growth of the communication industry. Firstly, inventiveness has led to advanced imprinting, telecommunications photography, radio and television. Secondly, speed has revolutionized the transmission (传输) and reception of communications so that local news often takes a back seat to national news, which itself is often almost eclipsed( 侵蚀) by international news.

No longer is the possession of information confined to(只限于) a privileged minority. In the last century the wealthy man with his own library was indeed fortunate, but today there are public libraries. For 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 that is being channeled into millions of homes.

Communication is no longer merely concerned with the transmission of information. The modem communication industry influences the way people live in society and broadens their horizons by allowing access to information, education and entertainment. The printing, broadcasting and advertising industries are all involved with informing, educating and entertaining.

Although a great deal of the material communicated by the mass media is very valuable to the individual and to the society of which he is part, the vast modem network of communications is open to abuse(滥用). However, the mass media are with us for better, for worse, and there is no turning back.
