Emerging Trend: Apple's iBeacon service, an opt-in geo-location system, will win over NFC (near field communication) technology with its ability to map locations in detail.
Implication: This represents an opportunity for OOH (out-of-home) marketers who are looking to bring their targets into stores. For instance, a retailer such as Best Buy will be able to push offers to those shoppers listening to music in the park and invite them to the nearest location to check out the latest digital music players.
Action: Build or partner with apps that leverage iBeacon technology. Target iPhone and other iDevice users.
