One of the most blatant and obvious forms of mainstream media fakery is the use of green screens, in which news reporters are superimposed on virtual backgrounds. As this compilation reveals, green screens are sometimes used to make it look like a reporter is on the scene, when, actually, he or she is merely on a soundstage.
What the viewer sees is often distorted simply by the camera angle, as in the case of the famous staged toppling of the Saddam Hussein statue after the first Gulf War. 
“Video news releases” (VNR) are a much less obvious form of fakery. “The use of radio and video news releases is a little-known practice which took hold during the 1980s, when PR firms discovered that they could film, edit and produce their own news segments — even entire programs — and that broadcasters would play the segments as ‘news,’ often with no editing…. Video news releases are designed to be indistinguishable from genuine news, and are typically used as ‘story segments’ on TV news shows without any attribution or disclaimer indicating that they are in fact subtle paid advertisements. ‘Most of what you see on TV is, in effect, a canned PR product. Most of what you read in the paper and see on television is not news,’ says a senior vice-president with Gray & Company public relations.”
