It created a 30 minute documentary about a Ugandan warlord, Joseph Kony.
He's the leader of the "Lord's Resistance Army" which is notorious for abducting, raping and maiming its victims as well as recruiting child soldiers.
An Invisible Children spokeswoman says the group plans to use any money raised from the video to build schools in Uganda and broadcast anti-LRA messages urging fighters to defect.
Critics of the organization say Invisible Children has manipulated facts in the past and warns viewers to watch the video with that in mind.
By Wednesday, the documentary had been shared millions of times via Twitter, Facebook and YouTube.
