NPR has looked at the behaviour of its audiences across all platforms, charting how content is consumed hour-by-hour over the course of an average week.

Radio remains NPR’s strongest distribution platform, with an audience of around 2,500,000 average quarter hour listeners on weekday mornings at 7:00am. Peaks in broadcast figures follow commuter times, with another high of around 2,000,000 at 5:00pm. Online audiences peak in the early afternoon with around 75,000 average unique visitors at 2:00pm, falling off gradually over the course of the rest of the day. Note the dual axes for comparing radio and online audiences.

Metrics for mobile show that NPR readers favour the iPhone over Android, iPad or mobile web, and peak earlier in the day than the online browser figures, with a little more than 8,000 unique visits at around 8:00am.
