Lets start by just assuming you don't know who John and Hank Green are...
The "Vlogbrothers" are a YouTube duo that began their channel in 2007, with the plan that they would communicate every day for a year via video-blog! Cool idea, right? Well it gets better! With this idea, that they entitled "Brotherhood:2.0", though they were publicly available videos, they really only started to actively gain notoriety about 6 months into the project, thanks to Hanks AMAZING song, "Accio Deathly Hallows", a song about the upcoming Harry Potter book (at the time). Thankfully when B:2.0 ended in the December of '07, they continued to make videos and have gained a huge global fan-base and in the last 5 years, 6 if you count the B:2.0 year, they have founded and created more awesome things than most people do in a lifetime!
