The majority of what he knows about stocks he learned right here at the Motley Fool. The video gaming industry is probably bigger than you think it is. Companies in the industry generate $180 billion in annual revenue worldwide. When compared with other entertainment sectors, that's bigger than the film industry ($100 billion) and the sports industry ($75 billion) combined.
