Newspapers, TV and the rest of the mass media have the primary purpose reporting news. They are also regulated in the sense that they cannot tell lies. But they have the ability to choose what to tell and to choose how to present it. They decide what sort of information is "important" for each of us.
But the thing is, this basket of news stories that serve us daily may distort our views of the world. Intentionally or not, serving only sensational news or negative news can create a negative worldview. It can also shape our ambitions and direction.
