John and Hank Green a.k.a Vlogbrothers
You guys know who I’m talking about! If you don’t, then you’re about to find out.
First off, let me tell you about each brother individually and then I’ll talk about what they’ve done together.

John Green is a #1 Bestselling Author on the New York Times Bestseller list. He writes Young Adult Fiction and is a well known vlogger on YouTube. His works include:
Looking for Alaska
Paper Towns
An Abundunce of Katherines
Will Grayson, Will Grayson
and his most recent novel: The Fault in Our Stars (and John Green signed every single first edition copy)

His brother, Hank Green, is a young entrepreneur, musician, and entertainer. He has produced videos for YouTube, NASA, The Discover Channel, and he has also written for The New York Times, Scientific American, and Mental Floss Magazine. His music is also available on iTunes.
Together, John and Hank Green started a project on YouTube called Botherhood 2.0 which challenged them to stop communicating through text message for a year and only communicate through video blogs. After their project ended, they decided to continue making videos with their new channel, vlogbrothers. They went from speaking once or twice a year to talking every single day.
Aside from Vlogbrothers, John and Hank Green have started a number of different YouTube channels, some dedicated to education (CrashCourse), fictional vlogs (The Lizzie Bennet Diaries), and sports. They are also the creators of VidCon, a large gathering of YouTubers and YouTube lovers filled with concerts, panels, and simply fun.
They also dedicate themselves to a number of project which they believe will “decrease worldsuck” like Project4Awesome and Kiva.
