When is it propagenda, when conflict of interest.

Propaganda can't be separated from conflict of interest anymore. So, it seems, especially in the media. No word is uttered without somebody paying for it, no picture shown without ulterior motive. That includes the writing of this blog. For me the difference is compensation. Of course news have always been sold to the highest bidder. But that bidder used to be the reader. Now the most important part of news is not the news anymore but the advertising sideshow. That's the way the Internet became profitable. But when is this type of recompense influencing the news itself, and when is it propaganda, and when is it conflict of interest? I'd like to know myself. I have read about propaganda. That will be in tomorrow's blog.
