When did the press turn from an information medium to a liberal Propaganda machine?

Question

I would hazard a guess it was during the sixties, but can anyone else confirm or prove otherwise?

Answer 1

It never did.

Just because it does not represent the viewpoint of some, does not mean it is a liberal, or conservative propaganda machine.

Answer 2

I would guess when you figured out that you conservative republicans are in trouble.

Answer 3

Well I think it did around the time of the Vietnam war. I think that is when the communist supporters took over our media.  

Answer 4

Ever since CNN started.
