What changed in the 2016 election is the torrent of foreign governments who were spreading outright lies in the interest of harming the country, and Americans who gleefully cooperated with them.
What has changed is the mainstream media used to care a lot more about being honest. Now they often couldn't give a toss.
I don't mind media being partisan, it's always been so, and often it's revealing to see the reporting from both sides of an issue, and add the FT's take for the financial slant. I do mind that we're rapidly running out of sources that care about being honest. Murdoch ruined the Times, the Barclay Brothers ruined the Telegraph. Both now far more opinion than news. That's a loss, whatever your politics.

Quite the contrary, in the USA, anyway. Think back to Hearst and the "yellow journalism" era.Never in the history of the world have individuals had such ease of access to original sources, such as eyewitness accounts, texts of legislation, etc. Yet people generally stay within their bubbles.
There is the argument that if people were equipped with the skills to identify bias in reporting themselves then these news sources would not be able to operate as effectively and with as much influence as they do today.
For example, in Swedish schools children are actively taught to identify and evaluate biases in news sources as a way to filter false reporting [1].
It we start giving children the toolbox required to live in our (real) world of imperfect reporting then the impact of biased news sources might be neutralized in a generation.

I understand it's considered axiomatic here to assume malice where stupidity would suffice as regards the media, but as you're attempting to argue against fabrication and deception by the media, your yourself are attempting to deceive readers here by conflating your case.
Perhaps you could add weight to your argument by listing the other fake news stories regarding ISIS from ABC?
The reporting could be a lot more balanced, presenting both sides, not using provocating headlines, etc.
It would probably be a bit more boring (which is why even previously serious publications like the Financial Times gave up).
