The Challenge: Persuade ‘Leisure Upgraders’ in the UK, that their needs and attitudes suit the Audible service, and drive them to sign up to an Audible 30-day free trial using an Out of Home (OOH) campaign. The Solution: Show how Audible fits into people's lives during the big and little changes, by highlighting the changes that they are experiencing and showing how Audible can help and suit their needs.
