municate with other people. A great deal of communicating is...uh...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...sort of um...conversations where we give information or opinions, receive news or comments, and.., uh...very likely have our views challenged by other members of society. Face-to-face contact is... is... by no means the only form. of communication, and during the last two hundred years, the art of mass communication has become...uh...one of the dominating factors of contemporary society. Two things, above others, have caused the enormous growth of the communication industry. Firstly OK... inventiveness has led to advances in printing, telecommunications, photography, radio and television. Secondly uh...speed has revolutionized the transmission and reception of communications so that local news often takes a back seat to national news, which itself is often almost eclipsed by international news. OK...so uh, lets say, 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.., uh... people used to flock to the cinemas, but now, far more people sit at home and turn on the TV to watch a program that is being channeled into millions of homes. Communication is... uh... no longer merely concerned with the transmission of information. The modern 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...ok...all involved with informing, educating and entertaining. Um, 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 a part, the vast modem network of communications is open to abuse. However, the mass media are with us for better, for worse, and there is no... no... turning back. Now get ready to answer the questions. You may use your notes to help you answer.Narrator Listen to part of a lecture in a mass media class. Now get ready to answer the questions. You may use your notes to help you answer.
