Facebook's fourth-quarter earnings was a bonanza for anyone looking for updated stats on the company. The one that caught a lot of analysts' attention was 23% -- the proportion of ad revenues that the company derives from mobile. Facebook's perceived lack of progress in mobile was a major reason the company's stock slid precipitously after its May 2012 IPO.

But, as usual, the company used its call with analysts after to show off its brisk growth and huge scale. Among the highlights:

  • On New Year's Day, users uploaded 600 million photos to Instagram, a new record.
  • Between Facebook's eponymous app and Instagram, the company now accounts for 25% of overall time spent on mobile, as measured by comScore.
  • 42 million users have claimed an offer through Facebook Offers so far.
  • Walmart ran a holiday campaign on Facebook that reached 50 million mobile users.
  • A Michael Kors campaign on Facebook advertising a new line of sneakers reached 36 million users.
  • FBX, the company's ad exchange service, served 1 billion impressions daily and is used by 1,300 advertisers per day.
  • Ad revenues grew 43% compared to Q4 2011.
