It's a 2.6B market for ALL MOBILE ads (of which banner ads are only .86 - http://www.emarketer.com/PressRelease.aspx?R=1008798 http://www.emarketer.com/PressRelease.aspx?R=1008798) So in 2014 it will be a 2B market - across ALL mobile. How big of a share can FB have - 20-30%? Still looks like a very small number.
