From a mobile + Facebook market dynamics snapshot

"The takeaway is this: if you’re a media company, you are almost certainly underestimating your Facebook traffic. The only question is how much Facebook traffic you’re not counting.

The bad news is that, if you didn’t know before, it should be even more clear now: Facebook owns web media distribution."
