Our happy hour fact to amaze your drinking buddy with.

In the first quarter of 2010, 37 percent of all the content hosted on the Internet was of a pornographic nature.

That number comes from Optenet, a global IT security company that boasts a "complex network of global intelligence, which permits efficient classification of all material on the Internet."

After porn, the next four content types are shopping (9 percent), travel (5.7), computing (4.2) and sports (4.2).

Of course, pornography has an advantage when it comes to total Internet volume: porn sites usually consist of bandwidth-hogging videos. If not for this, we believe the Web would be dominated by photos of cats.
