plzz Correct my essay about News Editor.

Broadcasting news is a complicated job. This job requires news-editors to decide what need to broadcast on TV or what to print in newspaper. In my opinion, there are two main factors infuences that job.
Firstly, programmes are broadcasted on TV or on newspaper, it must be a content-based life situation now: economy, politics, military... For a concrete example, the last event was the National Funeral of Genaral Vo Nguyen Giap. Vietnam's leader paid last respects to this independence hero. It's a hot news during last week. Who will read or watch your news if it happened a year or a month ago or even last week? Nowadays, society develops faster, which needs people keep pace with the rate of social life. Therefore, people' requirement should be updated fastly and information should be  more exactly . Updating hot news helps lots of people have more knowledge. Another factor, news-editors need to consider each kind of readers and watchers. After that, news-editors will distribute each of material object. It has been a great advantage to show programme on TV or on newspaper. So, what influences news editors' decisions the most is the age group of readers and watchers.
In fact, news-editors become used to bad news. Because, we can not deny that bad things occur in the world day by day. So we need to become used to that. Whether it's good or bad, we still read newspaper and watch TV to update daily news.
On the other hand, imagining that the news broadcasted on multimedia is bad news. It makes us worry and sad. I think it would be better if more good news were reported.
We can not live without good news. Clearly it makes us happier and comfortable. Why don't we become the optimist and wait for good news. It would be better for both news-editors and lots of people.
