The Midwest is a region of the United States of America known as "America's Heartland", which refers to its primary role in the nation's manufacturing and farming sectors as well as its patchwork of big commercial cities and small towns that, in combination, are considered as the broadest representation of American culture. In fact, most national television broadcasters speak with a midwestern accent. The Midwest was the home of more than one quarter of U.S. Presidents as well as the birthplace of the inventors and entrepreneurs of most of the technology that fuels the world's economy- examples include airplane, automobile, electric lighting, the transistor, petroleum, steel production. The Midwest is also home to abundant nature including the massive Great Lakes and the vast northwoods which cover northern Minnesota, Wisconsin and Michigan and spill over into Canada.
