In order to be well-informed, a person must get information from many different news sources.
There is an old Korean saying that the more friends you have, the more intelligent you are. The implicit meaning of the saying would be the importance of various sources of information. As the value of information is increasing with unimaginably fast developing world, having variety sources of information is becoming critical assets for modern people. (그냥 variety sources of information are critical assets~이렇게 쓰시든가요;ㅋ)
First of all, gaining information from various sources would broaden your knowledge base. Since technologies have been developing, new sources of information such as the internet media and satellite radio, have appeared. The more new media appeas, the more motivation to differentiate or specialize old media to retain readers occurs. The consequences of the phenomenon is that the( contents, media contain)>(그냥media contents), became narrower but deeper than before(or ; could be discussed more in depth than ever). In this sense, you should have more news sources to cover similar broadness of information you hadve. The book, named 'New wave of Media' showed this trend. The author of book claimed that as approximately 70% more media corporations have been established for past 10 years(10년동안 70% 더 많은 media corporations이 건립됬다는 말인가요? 70%more than what?), the area that 100 best-selling magazines cover has been narrowed by 20% for the same period.
In addition, having various news source is beneficial for accuracy. It seems to be avoidable that media have its own perspective. Unfortunately perspective of media often strains or omit facts. Here's a result of a study that a famous professor of Chicago University conducted. According to his research comparing Fox TV and Aljazeera about the news of Iraq war, he found that Fox often omitted the news about abuses committed by US military while Aljazeera exaggerated that. To avoid to make a mistake by believing strained news, gaining information from variety news source whose perspectives are different would be an effective way.
To sum up, it is quiet convincing to have various sources of information in terms of recent trend of media and their accuracy. The advantage of having various sources would outweigh your additional effort to cover more than a single source.
