The MSM are still powerful, but their might is declining. How many people under 30 watch any news or read any newspaper? I have professional colleagues who are grossly unaware of current events or history and who don’t even look at the three newspapers delivered to our office every day.
The Left is just as powerful over the online content as they were over the NY Times printed copy. Yes, there are other outlets but by and large reporters and editors lean (or wholeheartedly support) the Left.
