There's been a lot of commotion over Facebook’s purchase of WhatsApp, a messaging service that substitutes SMS messaging for free (or if you’re a long-time user, a small fee). As The Economist puts it, it’s the largest purchase of a venture capital-backed company thus far — and another big move in the tech industry’s own “Game of Thrones.” First, with Instagram, and now with WhatsApp, Facebook has been making some big moves to acquire companies that could substitute some of the very services that it provides to a larger audience.

But unlike Instagram, since the announcement, the WhatsApp team has reiterated their promise that there will be no ads on the platform. So, if there won’t be any ads, then why does this acquisition really matter to marketers? Well, let's get to the meat of it:
