Television has changed the life style of people in every industrialized country in the world. In the United States, where sociologists have studied the effects, some interesting observations have been made.
Television, although not essential, has become an important part of most people’s lives. It alters people’s ways of seeing the world; in many ways, it supports and sustains modern life. Television has become a baby-sitter, an introducer of conversations, the major transmitter or culture, a keeper of tradition. Yet when what can be seen on TV in one day is critically analyzed, it becomes evident that television is not a teacher but a sustainer: the poor quality of programming does not elevate (提高) people into greater understanding, but rather maintains and encourages the life as it exists.
The primary reason for the lack of quality in American television is related to both the history of TV programming development and the economics of TV. Television
A. advertisers are interested in experimenting with new ideas
B. it is still at an early stage of development, compared with the radio
C. the programs have to be developed in the interests of the sponsors for economic reasons
