As the marked development of electronic communication media, space is no longer the barrier that impede people to communicate with others, therefore our life was revolutionized,. But in this statement, the author claims that high-speed electronic communications media, such as electronic mail and television, trend to prevent meaningful and thoughtful communication. In my opinion, the author overstates the defect of electronic communications media but ignore their advance.
In the first place, electronic communication media such as electric mail and television accelerate the dissemination of science. Before the invention of electronic communication media, science were disseminated by print media which is a ineffective and costly media. Fortunately, electronic media succeeds overcoming those defects, which promotes the dissemination of science. On the one hand, once a thesis was published on internet, the people in every corner on the earth can read it immediately and conveniently. On the other hand, electronic media is superior in storing information, for example a CD-ROM can stock information that will take up a library if printed into books. The foregoing advance of electronic media make it a effective method to disseminate science.
In the second place, electronic communication media revolutionize business. Before the far-ranging use of electronic communication media, manufacturers and consumers hold only a little information, which affect their ability to pursue the maximization of profit and utility. Via electronic communication media, manufacturers can compare the price of raw material from different suppliers and the goods' price in different regions, so they can choose the cheapest raw material and sell their products at the highest price. While consumers can compare the price, quality and after-sale service of various commodities supplied by specific manufacturers, so they can make the best choose. On the other hand, the widespread use of electronic communication media save the time and energy of consumers to go to supermarket. They can purchase commodities on net and pay the bill via on-net banks. Abundant information promotes the completion among manufacturers, which forces them to make effort to improve productivity, therefore the well-being of society increases.
Last but not the least, electronic communication media break the barrier of space which used to stop people living far away from communicating with each other. Without electronic communication media, the key communication method is letters which take a week to be sent from New York to London. In many cases, a late letter makes no sense. For example, a person in London who suffered some trouble on occasion sends a letter to New York to ask for help from his friend. When his friend receive the letter a week later, it must be too late. Thanks to electronic communication media, the communication between people living far away has become much more convenient.
To sum up, electronic communication media revolutionize our communication method, which accelerate the dissemination of science and promote the development of business, besides, the revolution eliminate the barrier of communication between people living far away.
