That is a byproduct of the shift to 24 hour news on cable and now the internet. When the news was presented at specific times on TV, or once a day in newspapers, the emphasis was to have the best news, meaning your story was complete and accurate. Now it's just a race to have the story first. Accuracy? Pshaw, that can be figured out later, accuracy is a separate story.
Also (IMO), the byproduct of that is the continued dissemination of "fake news" as it were, with little regard for correction. A decade ago we would complain that the incorrect story was on page 1, but the correction was a little blurb on page 20. Now, with Twitter as "news" we have completely false stories making the rounds with 1,000,000 views and 50,000 retweets, and the accurate correction having 10,000 views and 100 retweets.
The first story out, right or wrong, is the one everyone hears and becomes "the truth". For any false stories, you have to dig hard to find the real truth, and no one seems to care when it's presented.
I saw an interesting story the other day, I think in The Atlantic of all places, about how Millennials and younger , while hating Trump, are agreeing with him on "fake news". They no longer take stories, whether from CNN or Fox, at face value without digging deeper. They have come to look at MSM news as "opinion", and they look to alternate news sources to confirm stories.
