Three years ago, Facebook didn't really have a mobile business. Now, mobile is its core business.

Facebook released its second quarter earnings report this afternoon, revealing revenues of more than $4 billion, and that mobile advertising represented about 76 percent of that revenue. That's up from 62 percent during the same quarter last year.

In June 2015, on mobile devices, the company says, it saw 968 million daily average users across all devices, with 844 million checking in daily on mobile, year-over-year increases of 17 and 29 percent respectively. That number grows considerably with monthly average users. Facebook says it sees 1.49 billion users over all as of June, with 1.31 billion checked-in on mobile. That's also an uptick from last year.

This enormous user base is what drives so much of the company's ad revenues. And the main story is that so much growth continues to come on mobile. Other companies continue to struggle on smartphones and tablets, which are clearly the future of computing, but Facebook very much has figured it out.

Notably, Facebook also said that its total costs and expenses in the second quarter reached $2.7 billion, an 82 percent increase over last year. Much of that is likely money spent on the data centers that underpin the company's social network. But, when you're winning, like Facebook, spending money on expansion is a very good idea.
