To the contrary, the "Fake News" term now seems to be used for any irresponsible or poor journalistic behaviour.
On Saturday, the earthquake authorities at the USGS had to make a statement about "fake news" in the coverage of the recent Searles Valley / Ridgecrest shakers. They told journalists and the news media that they had to stop making up click bait stories about these quakes being related to the coming "big one" and even that California was becoming a subduction zone. All were described as fake science used just to create headlines.
The indictment of all the news media in this case was very broad. False and misleading comments were made into real news stories but they lacked any factual basis. The implication here is that professional journalists have become no different from the writers at the Enquirer and that they make up stories to get the attention of readers.
"Fake News" is now, as the earthquake coverage showed, prevalent in all media. And it is not just the domain of the Trump administration.
I took my first journalism course in 1962 at Michigan State University, and what I saw in the last week violates everything I was taught.
