You notice the corruption of mass media when they cover a subject you are closely familiar with, but the general population can be easily misled on (say, political situation in an obscure corner of the world). They don't try too hard to be careful and maintain plausible deniability in these cases, and go for outright lies and extremely biased pieces. I've seen this happen too many times across a variety of news outlets, which makes me very skeptical of everything else I hear on the news. This recent scandal is not helping their image either.
