I'm pretty sure this has something to do with politics and what not.
All I know is that it refers to the media such as television. People who agree with this statement believe that there should be a well-informed public. The statment itself refers to the thin line that there is between factual news and pure entertainment. In other words, what is fact and should be taken seriously is now being misrepresented for the pure enjoyment of the public. The facts themselves might be twisted around greatly. As an example - there are people who cannot tell the difference between what is fact and what is not while watching television.
Everything is being sensationalized.
I might be wrong in my interpretation but I'm pretty sure I'm on the right track.
