One example that helps illustrate the effects of framing involves president Nixon's involvement in the watergate scandal. According to a study conducted by Lang and Lang, the media coverage at first belittled the watergate scandal and the President's involvement. It wasn't until the story was framed as one of the highest political scandals in US history that the public opinion changed (Lang & Lang, 1981) This event depicts how the media personnel have a great deal of power in persuading the public's opinions. It also suggests that framing is a form of gatekeeping, similar to the agenda setting theory.
