Art,
Facebook, has to roll out products pretty aggressively. They have to, custom audiences, new mobile ads formats, revamped there offers. And all of these do one thing, which is they help make ads more targeted, more useful, and more effective for marketers on Facebook. And how do they do that on a smaller screen?

Facebook has to prove to, advertisers that not only do they get a good return on Facebook ads, but they get a better return on Facebook ads compared to most things they do.They don't know what to do with their ads in mobile. Because their ads are on the right-hand side on the desktop. And when you go to a mobile device and you cut off that right-hand side, you know, where does the ad go? There most effective ads are now running through news-feed. And that creates a very natural opportunity to have a native advertising experience on mobile.
