The Economist is an English-language weekly news and international affairs publication owned by "The Economist Newspaper Ltd" and edited in London. It has been in continuous publication since James Wilson established it in September 1843. As of summer 2007, its average circulation topped 1.2 million copies a week, about half of which are sold in North America. Consequently it is often seen as a transatlantic (as opposed to solely British) news source.
