Focus on educational content As part of the platform's "YouTube Original Channel Initiative", YouTube approached John and Hank with an opportunity to start a Google-funded channels. YouTube gave the brothers $450,000, which they used to launch the Crash Course YouTube channel. The channel was teased in December 2011, and then launched on January 26, 2012, with the first episode of its World History series hosted by John Green.
