　　Television -- the most pervasive and persuasive ofmodern technologies, marked by rapid change and growth --is moving into a new era, an era of extraordinarysophistication and versatility, which promises to reshape ourlives and our world. It is an electronic revolution of sorts, madepossible by the marriage of television and computer technologies.

　　The word television, derived from its Greek and Latin roots, can literally be interpreted assight from a distance. Very simply put, it works in this way: through asophisticated system of electronics, televisionprovides the capability of converting an image into electronicimpulses, which can be sent through a wire or cable. These impulses, when fedinto a receiver , can then be electronicallyreconstituted into that same image.

　　Television is more than just an electronic system, however. It is ameans of expression, as well as a vehicle for communication, and as suchbecomes 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 broad-based airwave transmission of television signals. Second, there is nonbroadcast television, which provides for the needs ofindividuals or specific interest groups through controlled transmissiontechniques.

　　Traditionally, television has been a medium of the masses. We are most familiar with broadcast television because it has been with us forabout thirty-seven years in a form similar to what exists today. During thoseyears, 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, andentertainment. These giants of broadcasting have actually shaped not only television but our perception of it as well. Wehave come to look upon the picture tube as a source of entertainment, placingour role in this dynamic medium as the passive viewer.

　　电视电视--以快速变化与发展为标志的最普遍、最具有影响力的一项现代技术，正在步入一个极端复杂化与多样化的新时代。

　　这个时代承诺重新塑造我们的生活和我们的世界。这可以称得上是又一次电子革命，其关键在于电视技术与计算机技术的结合。电视这个词来源于希腊语词根和拉丁语词根，可以从字面上理解为来自远处的景象。

　　简单说来，电视是以这种方式工作的，通过一个复杂的电子系统，电视能够将一幅图像转换成能经过导线或电缆发送出去的电子脉冲信号。

　　当这些电子脉冲信号被输入一部接收机时，就可以用电子学的方法把脉冲信号重新恢复成同一幅图像。但是，电视不仅仅是一个电子系统，它还是一种表达工具和传播渠道。 因此，电视成了一个对其他人发生影响的强大工具。电视这个领域可以根据其发射方式分为两类。

　　第一类为广播电视，通过电视信号的宽带无线电波发射展现在大众面前;第二类为非广播电视，使用受控的发射技术来满足个人以及某些特殊利益群体的需要。电视早已成为大众媒介。 我们熟悉广播电视，因为广播电视已经以类似目前的方式存在了大约 37 年。

　　在那些年头中，电视绝大部分一直由 ABC、NBC、CBS 这些广播电视公司控制着，这些广播电视公司一直是资讯、信息和娱乐的主要提供者。这些广播业的巨头实际上不仅塑造了电视，而且也塑造了我们对电视的理解。我们渐渐把显像管看作是娱乐的来源，让自己成为这个生动的媒介的被动观众。
