Award for Excellence in Audiobook Production. Online video beginnings In 2007, John and his brother Hank began a video blog project called Brotherhood 2.0 which ran from January 1 to December 31 of that year and was published to their YouTube channel "Vlogbrothers". The two agreed that they would forgo all text-based communication for the project's duration and instead maintain their relationship by exchanging these vlogs. Each submitted one to the other on alternating weekdays. During that year, the brothers gained a large following during the early years of YouTube, especially after Hank's video "Accio Deathly Hallows" was featured on the front page of YouTube. In what would have been the project's final video, the brothers revealed that they would extend their video correspondence indefinitely. , they have continued exchanging their vlogs and the channel has over 3.5 million subscribers and 900 million views. Since the project's inception, the duo has gained a wide-reaching international fanbase whose members identify collectively as "Nerdfighters". One prominent early Nerdfighter was Esther Earl. Esther Earl was diagnosed with thyroid cancer in 2006 when she was 12, and developed a bond with the Green brothers and the Nerdfighter community. She would be involved with Nerdfighteria and YouTube until her death on August 25, 2010, at the age of 16. Green and the Nerdfighteria community continue to celebrate "Esther Day" each year on August 3, and support the non-profit foundation This Star Won't Go Out, founded by Esther's parents Wayne and Lori Earl. Earl's biography, co-authored by her parents, was posthumously published under the title This Star Won't Go Out: The Life and Words of Esther Grace Earl. Green wrote the introduction. Earl would later serve as an inspiration for the main character Hazel in The Fault in Our Stars. The group, in collaboration with the two brothers, promote and participate in several other humanitarian efforts and community events, including loaning more than $4 million through Kiva.org, as well as the Project for Awesome (P4A). The Project for Awesome, an annual telethon-style fundraiser held at first in December and later moved back to February, began in 2007. The event encourages participants to create videos promoting charities or non-profit organizations of their choosing. These videos lead up to a 48-hour livestream in which the charities are voted on by the community while supporters pledge money and receive donated perks like signed photographs, books, special events, and art
