Hank and John Green started a channel called Vlogbrothers at the beginning of January 2007. They started a year long project, entitled 'Brotherhood 2.0,' where they would "vlog" or post videos everyday, alternating for an entire year, except weekends. The two brothers never expected to get very big or go far with the project, but Brotherhood 2.0 eventually took off with a vengence. They started referring to their veiwers as "Nerdfighters." In which, they made a statement that it's okay to be different; to be a nerd; to be smart and out of the ordinary. This gave a place where nerds alike could finally show their true nerd pride, without being rediculed for it. Nerdfighters age from teens to adults and come from all over the world. Nerdfighters are concerned with the environment and helping children in Bangladesh. The series ended on December 31st, 2007, but Hank and John still make videos every week.
