Um. Not really. The media covers that which gets clicks / eyeballs. That gets turned into revenue via advertisers.

When you gather news from enough sources you start to see patterns in what gets a lot of attention, and what doesn't.

Long to short, you're naive if you don't think there's a straight line been the mainstrean news media and advertisers.

Note: The mainstream news media should also not be confused with journalism. The reasons are obvious.
