Television—the most pervasive and persuasive of modern technologies, marked by rapid change and growth—is moving into a new era, an era of extraordinary sophistication and versatility, which promises to reshape our lives and our world. It is an electronic revolution of sorts, made possible by the marriage of television and computer technologies.
The word "television", derived from its Greek (tele : distant)and Latin (vision. sight) roots, can literally be interpreted as sight from distance. Very simply put, it works in this way: through a sophisticated system of electronics, television provides the capability of converting an image (focused on a special photo-conductive plate within a camera) into electronic impulses, which can be sent through a wire of cable. These impulses, when fed into a receiver (television set), can then be electronically reconstituted into that same image.
Television is more than just an electronic system, however. It is a means of expression, as well as a vehicle for communication, and as such becomes a powerful tool for reaching other human beings.
The field of television can be divided into two categories determined by its means of transmission. First, there is broadcast television, which reaches the masses through broadbased airwave transmission of television signals. Second, there is non-broadcast television, which provides for the needs of individuals or specific interest groups through controlled transmission techniques.
Traditionally, television has been a medium of the masses. We are most familiar with broadcast television because it has been with us for about thirty-seven years in a form similar to what exists today. During those years, it has been controlled, for the most part, by the broadcast networks, ABC, NBC and CBS, who have been the major purveyors of news, information, and entertainment. These giants of broadcasting have actually shaped not only television but our perception of it as well. We have come to look upon the picture tube as a source of entertainment, placing our role in this dynamic medium as the passive viewer.
What field of television is intended for specific interest groups?
选项
A、Broad based.
B、Reconstituted.
C、Traditional.
D、Non-broadcast.
答案
D
解析
在第四段最后一句中就可找到有关信息:“there is non-broadcast television,which provides for the needs of individuals or specific interest groups",因此可以肯定D 为正确答案。
