Brotherhood 2.0 was a project started by John and Hank Green in 2007 In an effort to reconnect as adult brothers. They filmed videos every weekday for the entire year, alternating days between the two of them, posting the videos on their YouTube channel (vlogbrothers). During the year, they were forbidden from communicating via literary means (email, text messaging, etc.), only communicating through the vlogbrothers channel and telephone. If they did communicate literarily, or if they missed a day, they would be punished.

Over the course of the year, a community sprang up around their YouTube channel, sparking the movement of Nerdfighteria.
