The modern media has undoubtedly increased the awareness of disasters in all parts of the world. In many cases, this awareness has resulted in increased aid and humanitarian response.
Of course, the media can also be manipulated by skillfull politicians for their own benefit. It can draw funding to an afflicted area which is then stolen. It can be used to accuse authorities of conspiratorial acts of terror for the political gain of someone else (see Hurricane Katrina).
Like everything else, it can be a tool for good or evil, depending on how it's used and who is using it.
