So they can know what is happening around them :) Yet the media sells it and you live the role. Don't get caught up in the mix cuz the media is full of dirty tricks. Bottom line is DON'T believe everything that you watch on TV because you won't know if those news guys tells the truth :)
So they can be informed of what is going on in the world and locally. Albeit some stations are biased politically, you can at-least be aware of what's going on. It shows that they care and want to be smart on what is going on.
