It's a question I have heard outsiders ask quite a few times during my 40 years or so in the news business: How do journalists produce those long, deep feature obituaries so quickly after the death of a major newsmaker?

The answer, of course, is that these lengthy obituaries are written far in advance and then quickly updated when the subject of the profile passes away. This puts reporters in an awkward position, since they often need to call experts and insiders for comment on the meaning of a famous person's life and work, even though this person is still alive.

So when do journalists start producing this kind of feature package? Basically, the more famous the person the earlier newsroom prepare for their deaths. I am sure that The Los Angeles Times already had something ready when superstar Robin Williams died, because of his stature and his history of struggles with drugs and depression.

All of this is to say that major newsrooms have had obituary features ready about the Rev. Billy Graham since -- oh -- 1955 or so. I know that I worked on some Graham obit materials for The Rocky Mountain News (RIP) back in the 1980s. I have known, for several decades, the basic outline of the "On Religion" column I plan to write about his legacy.

You can hear the ticking of this clock in a new Religion News Service feature written by Godbeat veteran Cathy Lynn Grossman, which focuses on the 1949 event when Graham's path cross that of another major figure who is currently in the news -- Louis Zamperini.
