The family of SciShow YouTube channels (that include SciShow, SciShow Kids, and SciShow Space), helmed by Vlogbrothers Hank and John Green, grew from a side project in 2012 to a full-fledged, nationally advertised YouTube superchannel in 2014. Four days a week, they crank out videos answering complex and far-reaching science questions to an audience of more than 3 million. Want to know about the flavor compounds in your Pumpkin Spice Latte? Wondered what causes pins and needles? Can you catch Alzheimer’s disease? SciShow answers these questions with the help of special guests, shorter videos answering quick questions, and longform videos diving deep into a topic of their choice.
