In 1987, the same year Hulk Hogan body-slammed Andre the Giant, something else happened that would change America's relationship with the truth forever - a Washington regulator abolished the law that required broadcasters to present both sides of an argument.
What followed was Morton Downey Jr, a furious chain-smoking provocateur who discovered that outrage was more compelling than accuracy. And Oprah Winfrey, who found that sincerity and emotional honesty could be just as powerful. Together, they popularised an idea that has quietly shaped the world we live in - that your truth is just as valid as the truth.
