Facebook's bet on mobile continues to pay off in absolute spades. The first quarterly earnings report of the year from Zuckerberg and crew lay testament to that, showing that a whopping 73 percent of its $3.32 billion in ad revenue now comes from mobile alone (Total revenue for the quarter was $3.54 billion). Its number of mobile users is also on the rise -- out of Facebook's 1.44 billion monthly active users,1.25 billion are on mobile, which is up 24 percent from this time last year. Perhaps more impressive is that the number of daily users -- ie. its most engaged audience -- has gone up as well; 936 million people visit Facebook everyday, with 798 million of them logging in from their phones.
