The old days of passive consuming are slowly passing by. To keep up with the new media consumption habits, where people actively interact with media or content, brands needs to enable that. Basically it's about making users of your customers. A user is per definition actively doing something, the opposite is passively consuming. That's the key point - Give your customers reasons to interact with your brand.
By constantly offering valuable* content brands build a natural interplay with customers.

Certainly easier said than done. Not necessarily digital, but it's certainly the easiest way to execute interactive ideas.

*Meaningful, entertaining, useful, non-interuptive etc.
