Fake News may be partly F_ c_ Uped  news, more then faked news. 
Those who call themselves "journalist" seem to have forgotten what the Five Core Principles of Journalism are.
1) Truth and Accuracy. Journalists cannot always guarantee 'truth', but getting the facts right is the cardinal principle of journalism. ... "Accuracy entails honesty in sourcing. Our reputation for that accuracy, and for freedom from bias, rests on the credibility of our sources."  
2) Independence. ...
3)Fairness and Impartiality. ...
4) Humanity. ...
5) Accountability.
Getting the facts right as well as truth would be nice with credibile sources. 
Try reading "new articles" not op/ed, and see how they measure up. How many times does the writer interject their feelings or beliefs ? I am talking about Reuters and AP stories and the lack of Impartiality. A word here or two there is sometimes all it takes to "slant" a story.
The importance of sources is a key part in the "Handbook for Journalist" by Reuters.
