Creating a video that really goes viral (like, 10 million free views viral) is hard. It's really, really hard.
The truth is that most videos don't go viral. The people you send the video to see it, and they might send it to a friend or two, but generally it fizzles out.
So what goes into a great viral video?
Well, lots. But ones of the ways to learn is to see what works. (Duh.)
Presented in this post on Politico.com are the 10 most viral videos of the campaign (the American presidential campaign, that is).

Take a look through them. They're pretty interesting viewing, to say the least.
