"Six corporations own 90 per cent of the media companies in the US, according to a report by Business Insider. What most Americans read, watch, and listen to is filtered through those corporate interests. And media that isn't corporate-owned is often corporate-sponsored. National Public Radio, for example, took funding from America's Natural Gas Alliance, which leads those who oppose fracking to point out how weak NPR's reporting is on the topic.
"Propaganda by omission is something to watch out for," Daymon Hartley, former photographer for the Detroit Free Press, told DeSmog. "Now corporations control what you see and what you don't see. They look through lens of their own ideology and control the message by hiding what it doesn't want you to see."
Ownership of the media dictates the tone of editorial content, as well as the allocation of resources to cover stories. Not reporting on a topic can tell us as much about a news source's stance as the topics it does cover – as do the images we see and don't see."
