If the mainstream media is so left-wing, why has Bernie Sanders received 1/80th (not a typo) the coverage of Donald Trump?
A lot of liberals may work in media, but the mainstream media itself is profit driven. This is true regardless of network. 24-hour news networks (mostly) don’t sell agenda, they sell sensationalism. They sell what people want. It’s a ratings fight so they can sell advertising, pure and simple. That’s why the bombshell story is always “coming up after the break”.
I’ll bet $20 there’s a corresponding amount of sensationalism to ratings for any given show on any given 24-hour news channel.
