The paid content masquerading as journalism is particularly irritating. You can also see similar bias in the regular news stories. There are lots of tricks you can use to color the facts of a story to get the audience to respond in a particular way.
Lighting, framing, background, ambient sounds, subject placement--all these things can be employed for rhetorical effect. For instance, authority figures might be filmed at a slight upward angle from below the eye line, to make them appear slightly taller than anyone viewing the image. Fat people will be filmed from shoulders up if favored, from the waist up if unfavored, and from the neck down for vaguely defamatory stories. Pay attention to whose faces are shown with police mugshots, and whose faces are shown with license photos, military photos, school photos, or photos intended for other purposes. Watch out for different wording in captions and infobars. Listen for odd euphemisms that suddenly pop up in several places at once, or for different people who mysteriously say almost exactly the same things, as though they read from the same script.
It's almost harder to see anything that isn't a fnord.
