Despite the silence from Facebook on the matter, the company has made moves in the past that would indicate at least a desire to further its reach in the mobile advertising market. Last year, Facebook released Audience Network, which is meant to build out its infrastructure and enable advertisers to run Facebook ads on third-party mobile phones. Another such program is Atlas, which tracks users anonymously and provides feedback to advertisers. Facebook has also taken out a patent on a program that would enable advertisers to target only the most “influential” people on social media. Theoretically, these programs would be stitched together as part of any MoPub-like system.
