The Wall Street Journal published an interesting overview piece on Facebook founder Mark Zuckerberg's evolution and maturation as a CEO. One of the most amazing aspects of Facebook's post-IPO growth and "turn around" has been mobile. In a little over a year the company has gone from less than $100 million to more than $800 million in mobile ad revenues.
"Taking Facebook public and reshaping it around mobile phones forced him [Zuckerberg] to grow up," assert unnamed sources in the article. The WSJ credits Zuckerberg individually with driving the transformation of Facebook's mobile business though an increasing focus on the bottom line.
In Q2 2012 Facebook reported mobile ad revenue of roughly $69 million against overall ad revenue of more than $990 million. In Q3 2013 (the most recent quarter available), Facebook advertising revenue was $1.8 billion. Mobile delivered 49% of that amount or approximately $882 million.
Facebook said in Q3 it had 728 million daily active users and 1.19 billion monthly active users, up 18 percent. Monthly active mobile users totaled 874 million on a global basis and mobile daily active users came in at 507 million.
When Facebook reports Q4 2013 revenue it's certain that mobile will account for more than 50% of total ad revenue. Overall, in 2013, it's likely that Facebook will have made about $2 billion in mobile ad revenue globally.
