The media can impact current events. As a graduate student at Berkeley in the 1960s, I remember experiencing the events related to the People’s Park that were occurring on campus. Some of these events were given national media coverage in the press and on TV. I found it interesting to compare my impression of what was going on with perceptions obtained from the news media. I could begin to see events of that time feed on news coverage. This also provided me with some healthy insights into the distinctions between these realities.

Electronic media are having a greater impact on the people’s lives every day. People gather more and more of their impressions from representations. Television and telephone communications are linking people to a global village, or what one writer calls the electronic city. Consider the information that television brings into your home every day. Consider also the contact you have with others simply by using telephone. These media extend your consciousness and your contact. For example, the video coverage of the 1989 San Francisco earthquake focused on "live action" such as the fires or the rescue efforts. This gave the viewer the impression of total disaster. Television coverage of the Iraqi War also developed an immediacy. CNN reported events as they happened. This coverage was distributed worldwide. Although most people were far away from these events, they developed some perception of these realities.

In 1992, many people watched in horror as riots broke out on a sad Wednesday evening in Los Angeles, seemingly fed by video coverage from helicopters. This event was triggered by the verdict (裁定) in the Rodney King beating. We are now in an age where the public can have access to information that enables it to make its own judgements, and most people, who had seen the video of this beating, could not understand how the jury (陪审团) was able to acquit (宣布……无罪) the policemen involved. Media coverage of events as they occur also provides powerful feedback that influences events. This can have harmful results, as it seemed on that Wednesday night in Los Angeles. By Friday night the public got to see Rodney King on television pleading, "Can we all get along" By Saturday, television seemed to provide positive feedback as the Los Angeles riot turned out into a rally for peace. The television showed thousands of people marching with banners and cleaning tools. Because of that, many more people turned out to join the peaceful event they saw unfolding on television. The real healing, of course, will take much longer, but electronic media will continue to be a part of that process.
