Vlogbrothers

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.”
