It influences people who will watch it. There’s a large swath of the population that can quite easily fall for some of the shit they are going to peddle. Look at what Fox News does to the US when they present outright lies as news.
Not many people watch these news channels and those that do are generally only looking to confirm their existing biases. Or just watching for the crazy....I used to watch the opening to Hannity just to see what the cnut was pushing that night and laugh at how they twist a story.
