I don't think that happened in a vacuum, but they have acquitted themselves poorly over the last 4 years. To a large extent media audiences self segregate and demand certain content, and media companies have responded by tailoring their products. That probably further narrows their appeal. I have to imagine that some of these news orgs will simply fail once they become too narrow and audience preferences shift again. News operates in a market just like anything else.
