The media has always impacted how we view acts, if they are monstrous or not, and how we view people or things, if they are monsters or not. An example of this in a more present day situation, is like the picture behind. It shows a regular muslim man crying for help, but the media has made him resemble a terrorist. This is a twisted view that the media has given him.
Another example from much earlier is the Salem Witch trials. In the Salem Witch Trials, everyone was on edge that some woman they knew was a witch. Of course, witches don't exist, but people were sentenced to death, because the media instilled fear into people and in this way the media and its ability to spread like a plague killed a lot of innocent women.
