Hank Green started making YouTube videos in 2007 with his brother, John. They thought it was a pretty dumb idea, but it turned out pretty well. He is now the Executive Producer of SciShow, Crash Course and nearly a dozen other educational YouTube channels, and co-founder and CEO of NerdCon and VidCon, DFTBA Records, a merchandise fulfillment company, and DFTBA Games, a tabletop gaming company. He is co-founder and Executive Producer of Pemberly Digital, co-founder of Project for Awesome, and a Billboard top ten musician. He has also written for a variety of publications, including The New York Times, Scientific American, and Mental Floss Magazine. His most recent projects include launching the Internet Creators Guild, creating the YouTube series How to Vote in Every State, and, of course, bringing this community together for NerdCon: Nerdfighteria.
