Corporations will fight to preserve those fictions that they believe best sell their products. These fictions, after all, translate into real choices and real purchases. The cash register is a voting booth. Every dollar spent represents a belief, a buying in to a marketing fiction. Stories represent profit.
Stories represent lifestyles and values.

But for me, Jesus will always straddle the line between fact and fiction. Perhaps that's the common thread to these lasting stories.
