In 2007, brothers Hank and John Green lived thousands of miles apart, so they started posting video blogs to each other on a strange new platform called YouTube. People began tuning in, and the daily Vlogbrothers posts became an early viral hit. Over time, the brothers grew that single channel into a sprawling collection of businesses, including a production studio—Complexly—that makes some of the most entertaining educational content on the internet. They’re also both hugely successful authors; John’s young adult novel The Fault in Our Stars is one of the best-selling books of all time. With every success, Hank says he’s asked himself, “What’s exciting? What’s causing you the most stress? Head in that direction.”See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
