The Vlogbrothers is a video bloggers ("vloggers") series broadcast on Youtube. The Internet-based show is created and hosted by brothers, John Green and Hank Green, who utilize a registered YouTube channel that allows viewers to become subscribers. The first incarnation of the brothers' online broadcasting was the "Brotherhood 2.0" project, preceding the establishment of the pair's regular vlogging activity through the Vlogbrothers channel. The Greens state that their vlog has no steadfast format: _Really, it's not about anything in particular. Whether we're talking about our lives, making each other laugh, or trying to get something more important across, people seem to enjoy it._ The Green brothers devised the Brotherhood 2.0 project late in 2006. The project was launched on January 1 of 2007, based on the premise that the brothers would cease all text-based communication for one year and, instead, converse by video blogs every weekday.
