A leading innovator in the field of digital marketing, Jeff Rosenblum recently completed a documentary about the future of the advertising industry, titledĀ The Naked Brand.

We had a chance to visit with Jeff when he stopped by Motley Fool headquarters in January. He told us how his industry is dying, how it is being reborn, and how smart companies -- and the whole world -- will be a lot better off as a result.

In this video, Jeff gives a surprising perspective on who is winning the social media advertising battle. Hint: it's not Facebook!
