European explorers reveled in their versions of a mappa mundi, or map of the world. Such representations were worse navigation aids than Apple maps on a bad day--but marvelous pictorial representations of relationships and principles. When the NewSchools Venture Fund issued its first "edtech market map" last October, many found it a useful catalogue of companies, even if the industry was moving quickly. Today NewSchools updated its map. This version includes 50 additional companies, fresh information on products and deals, and some adjustments in the categorizations. You can see the map here.
