The Southeast economically has changed dramatically since the late 20th century. There has been a boom in its service economy, manufacturing base, high technology industries, and the financial sector. Examples of this include the surge in tourism in Florida and along the Gulf Coast; the numerous new automobile production plants such as Mercedes-Benz in Tuscaloosa; Hyundai in Montgomery; Toyota Motors in Blue Springs, Mississippi; Kia in West Point, Georgia; BMW production plant in Greer, South Carolina; Volkswagen in Chattanooga; GM manufacturing plant in Spring Hill, Tennessee; and the Nissan North American headquarters in Franklin, Tennessee; the two largest research parks in the country: Research Triangle Park in the Triangle area of North Carolina (the world's largest) and the Cummings Research Park in Huntsville, Alabama (the world's fourth largest); and the corporate headquarters of Verso Paper and FedEx in Memphis.
