HowStuffWorks is an American commercial edutainment website that was founded by Marshall Brain with the goal of giving its target audience an insight into the way in which many things work. The site uses various media in its effort to explain complex concepts, terminology and mechanisms, including photographs, diagrams, videos and animations, and articles. A documentary television series with the same name also premiered in November 2008 on the Discovery Channel.
