One core tenet of media is "the more you repeat something, the more people will believe it." This is why we are bombarded with advertising - so that the brand name occupies a larger region of our minds.
Unfortunately, whereas advertising is simply driven by the desire for profit, other applications of media are even less commendable. I am referring to the political uses of media, that have given us among others the first tragedy of the 21st century, 9/11, as the century had just been born.
How does media - the discipline - manage such success?
