This is a concept I've been pushing for a long time at Audible. It looks like it might actually happen sometime in the near future.
It seems like a no-brainer, but Audible doesn't actually allow users to take extended samples of the Audiobooks on the go and make the decision to buy after they've listened for a bit.
Its a mystery to me, because unlike movies, books or just about any other kind of digital media, many people don't understand what an Audiobook is. Consider trying to sell a television to someone who has never watched TV before. Hard, right?
Fortunately this storyboard went a long way to getting a "non-starter" conversation, well, started with the right people.
