Having reached 100 million views in six days, Invisible Children's 30 minute documentary "Kony 2012" is believed to be the fastest spreading viral video of all time.

So if you haven't seen it yet, there it is above. Go ahead and take the plunge.

"Kony 2012" tells the story of the brutal Ugandan warlord Joseph Kony, who is accused of amassing armies of child prostitutes and soldiers. The video is epic in tone and explicitly sets the goal of leveraging the power of social media to spread important ideas.

Since its launch a week ago today, Kony has inspired a slew of responses on social media, among celebrities and in the news media. Both the Wall Street Journal and The New York Times have published reports on the remarkable success of the video.

Visible Measures, a research group that has tracked Kony 2012's spread, said its 112 million views came from over 750 copies of the video that were posted on the web. Invisible Children first posted the doc to Vimeo and then to YouTube.

The second most viral video ever, according to the group, was Susan Boyle's breakout performance on Brittain's Got Talent.
