One in 8 Million is an award-winning series produced by the New York Times. It uses the basic multimedia format of an audio slideshow. The photographs produced in black and white by Todd Heisler are accompanied by audio interviews that profile New York City residents who live interesting but uncelebrated lives. Unfortunately, the series was abandoned after 53 episodes.
Think of the storytelling photographs as b-roll and the audio interview as primary story and you will begin to understand the basic building blocks of multimedia and video stories.
