Many brands — and software companies for that matter — claim they're doing mobile marketing. Call it what you want, mobile first, mobile-centric, what they generally mean is that they can take exactly the same content you'd find on a website or email and display it relative to the screen size it appears on. When you boil it down to its bare elements, that's what they are really doing — i.e., responsive design. Sorry to say, but responsive design does not a mobile strategy make. It by no means covers the potential that true mobile marketing really represents. 

If sex sells, then nudity can't be far behind. At least that's what Zappos hopes with its new advertising campaign featuring naked models doing everyday things like jogging, hailing a cab and playing Frisbee in public.
