Radio is also a social media. Any media which allows you to come together, interact, comment and participate in a discussion is a social media. Internet by itself is not social media; applications like Facebook make it social. Similarly, radio also has certain elements that drive participation, social interaction and communication. In that sense, I do not see that radio and social media are competing.
The beauty of social is it tells where people are right now, so with the help of analytics we can predict where they can be. The advantage to marketers is that they can give consumers what they want, before they know they even want it. The process of connecting the right consumer to the right product at the right place, which earlier normally took three weeks, now takes 500 milliseconds; that is a game-changer, that is the power of social.
