While Google struggles with the transition to mobile, Facebook's making it look easy, reporting that it made 41 percent of its $1.81 billion in revenue this quarter from phone based advertising. That's up from 30 percent last quarter — enough to satisfy Wall Street this time, with stock trading up over 17 percent in after-hours trading. The gain last quarter showed the beginnings of this trend, but at the time investors felt Facebook spent too much money on developing products to justify the gain. 

With a lot of the fear these days surrounding consumer shift from computers to smartphones killing ad revenue, CEO Mark Zuckerberg highlighted the achievement in the release. "We've made good progress growing our community, deepening engagement and delivering strong financial results, especially on mobile," he said . "The work we've done to make mobile the best Facebook experience is showing good results and provides us with a solid foundation for the future."
