It's hard to imagine today now that Facebook is so entrenched in our lives, but back in 2012, the company was widely derided by the financial press.

The conventional wisdom was that Facebook wouldn't be able to monetize its users and was part of a second Internet bubble inflating in front of us.

Facebook is up 348% since that date vs. the market's 48% gain.

It released earnings earlier this week that were once again stunning. It now averages more than a billion users on its sites and apps a day, not to mention revenue soaring 40% last quarter.

And, of course, Facebook is far from some profitless wonder. In the last quarter alone, its operating profit was $1.5 billion.

Churning through Facebook's earnings, a simple stat will blow your mind.

Facebook is now larger than any bank in the world!

It's larger than Wells Fargo, Bank of America... You name it!

As of Thursday night, Facebook was worth $293 billion. That's $15 billion more than the world's largest bank!
