Vlogbrothers

Vlogbrothers (sometimes stylized as VlogBrothers or vlogbrothers) is a video blog channel on YouTube. The Internet-based show is created and hosted by the Green brothers: John and Hank. 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 Vlogbrothers channel was the first in what would become a larger portfolio of YouTube channels created and developed by the Greens, sparking a community of fans and supporters of Vlogbrothers, known individually as Nerdfighters, and collectively as Nerdfighteria. Subscribers of the brothers on YouTube are the base of the online community Nerdfighteria. The Green brothers encourage their viewers to become a community by creating websites and various projects, like the Project for Awesome, as a way to engage with their subscribers.
