What is an expository journalism?

Expository writing is meant to inform, to "expose" the facts of a story and provide the reader with a thorough exploration of the topic. Expository journalism applies this to the world of news: it investigates a topic and then offers the reader, listener, or viewer a thorough and informative piece that gives new insight into the particular issue. A good example of expository journalism is "Bonding for Profit," a three-part investigative series that ran on National Public Radio in 2010. The three episodes looked at unfairness and corruption in the bail bond system, and the series won the Alfred I. duPont-Columbia University prize for Excellence in expository journalism.
