Huge job cuts. Many journalists are now doing work of multiple positions in many places especially online media. New York Times has reduced the number of their total editors in the last 10 years for example. Every major online media had layoffs comparable to 10% of their total workforce in the last 5 years. It affects mid level journalists the most so there are more interns now.
Most of the jobs have been concentrated geographically. Whatever people say, environment changes how they act and what they believe in the most, likely to report.
There isn't enough exclusive content. Any big announcement or what rich people say can be read on social media by directly following their account. Why buy a NYT subscription for that?
There are thousands of big YouTubers reading the latest news from NYT to their subscribers and taking NYT's cut if they actually do something exclusive and costly.
News has become an entertainment commodity for people. The vast explosion of content means fewer people are willing to pay for less but greatly researched content compared to more content and noise.
