There are many people out there who like to read about divorce stories, particularly stories that involve celebrities and plenty of drama. Newspapers and magazines are well aware of this fact, as they plaster big, bold divorce headlines on their covers that seem like they could be read from outer space. You can't miss them as you wait in line at your local grocery store.
In a vacuum, this isn't necessarily bad. People take pleasure in a variety of hobbies and activities. But in many ways, the portrayal of divorce and discontent relationships is bad for everyone involved. Of course, it is bad for the two people going through the divorce. It's also bad for the reader, as it desensitizes them to serious and far-less-dramatic nature of divorce -- which accounts for the vast majority of splits.
