The media will tell you that no story sells better than a fall from grace. Exposing other people's sins is a lucrative business, especially when the one exposed had been up on a pedestal.
The murder trial of O.J. Simpson back in the 90's became an industry in itself. Why? Simpson had always been a good guy, someone we looked up to who had risen from a broken home and poverty and made it in society through talent and hard work. Everybody loved O.J. Then he had a spectacular fall from grace, accused of brutally killing two people, one being his wife and the mother of his children.
This was in the days before Internet, so people were glued to their TV's soaking in every aspect of the trial. It was the main topic of conversation in America and around the world. I remember when the verdict was announced. It was in the middle of a work day, and we were actually allowed to stop working and watch it on TV, as if this was some momentous historical event.
We have seen this scenario played over and over again with celebrities. Although the stories are important to the people involved, for most of us these incidents have no effect on our lives whatsoever. Yet we still watch them and try to learn every sordid detail.
