Here comes digital audio’s revenue J-curve.

Dozens of advertisers are piling in each week with campaigns using new audio advertising options from “shake-your-phone” response ads, location-based messages and even automated audio ads carrying tailored messages based on user locations. The rich data available via digital audio consumption is also being used to inform and deliver brand campaigns.       See omnystudio.com/listener for privacy information.
