The media is corrupting our society. Do you agree?

The first response to this question from many people would be a firm nod of agreement. After all, the media IS a powerful tool in influencing many of our decisions and perceptions of situations. However, if one were to delve deeper into this issue, the answer may not seem as distinct as it originally appeared.
It is undoubtedly true that there are instances where the media is seen to corrupt our society. Cho Seung-Hui, the university student who shot and killed 32 people, is claimed to have been influenced by the movie "Oldboy" because of one of his photographs sent to NBC was said to have been in a position similar to an image used in promoting the movie, even though this was later proved to be untrue.
The fear of the media's ability to corrupt society is further displayed when they were requested by Peter Read, the father of a victim in the Virginia Tech massacre, to "stop airing Cho's manifesto".
Besides this, there have also been accusations from Jack Thompson, an infamous character in the gaming community due to his strong views against video games with violence, that many musical performances contain obscenities and should not be released.
However, we have to first look at how the media is defined. Is the media to be regarded as an entity entirely separate from the society? Or is it just a label for a part of the society that attempts to communicate with the rest of the society? Of course, the media cannot exist without humans from the society controlling it. From the above examples, it can also be seen that the fears of our society being corrupted by the media stems from members of the society, be it Cho Seung-Hui, NBC, the gaming industry or even Jack Thompson.
The act of corruption can therefore not be blamed entirely on the media, but rather, the members of society who abuse it to corrupt the society. Thus, a more appropriate question to ask now would be, "Is our society corrupting itself?"
