Just found this site, Twistcontent, and found it to be a potentially devastating way to get traffic to your site from peoples' phones. I am not affiliated with this. It is a new company and you can start an account for free and set up one campaign for free, but there are the usual stipulations: no porn, no spammy commercial pitch, etc. But if you put your BH thinking cap on and post a wallpaper with your site name watermarked or have content that leads to a pre-sell/user-friendly content landing page, I can see how the more clever BHer could make a quick buck. I am not sure how saturated this could get if you are adding value, the more traffic would be welcome.
