The economy of Salt Lake City, Utah is primarily service-oriented. While nearby Bingham Canyon Mine (the world's largest open-pit mine) provided a strong source of income during the 19th century, the city has evolved to an economy built on transit hubs, call centers, and seasonal tourism. The 2002 Olympic Winter Games gave a great boost to the area's economy. Many hotels and restaurants were built for the 2002 Olympics, and although many survive, they have suffered post-Olympic market saturation.
