As the “home of country music”, Nashville has become a major music recording and production center. All of the Big Four record labels, as well as numerous independent labels, have offices in Nashville, mostly in the Music Row area. Nashville has been home to the headquarters of guitar company Gibson. Although Nashville is renowned as a music recording center and tourist destination, its largest industry is actually health care. Nashville is home to more than 300 health care companies, including Hospital Corporation of America, the largest private operator of hospitals in the world. The automotive industry is also becoming increasingly important for the entire Middle Tennessee region. Nissan North America has its corporate headquarters in Franklin, southwest of Nashville. Nissan also has its largest North American manufacturing plant in Smyrna, Tennessee. Largely as a result of the increased development of Nissan and other Japanese economic interests in the region, Japan moved its New Orleans consulate-general to Nashville’s Palmer Plaza. Other major industries in Nashville include insurance, finance, and publishing. Fortune 500 companies with offices within Nashville include Dell, HCA and Dollar General.
