RAD was piloted in 2017 with a cross-departmental team at NPR. More information on this pilot is available at the NPR One Dev Center. The pilot ran for about six weeks in the NPR One iOS application. Listening events were sent to an analytics server for select podcast episodes that were hand-coded with V1 RAD tags. This pilot provided a successful proof of concept that encouraged NPR to pursue further development with other podcasting stakeholders.
