Tourism in the United States is a large industry that serves millions of international and domestic tourists yearly. Tourists visit the US to see natural wonders, cities, historic landmarks, and entertainment venues. Americans seek similar attractions, as well as recreation and vacation areas.
Tourism in the United States grew rapidly in the form of urban tourism during the late nineteenth and early twentieth centuries. By the 1850s, tourism in the United States was well established both as a cultural activity and as an industry. New York, Chicago, Boston, Philadelphia, Washington, D.C., and San Francisco, all major US cities, attracted a large number of tourists by the 1890s. By 1915, city touring had marked significant shifts in the way Americans perceived, organized, and moved.
