Las Vegas is the most populous city in Nevada, United States, the seat of Clark County, and an internationally renowned major resort city for gambling, shopping, and fine dining. Las Vegas, which bills itself as The Entertainment Capital of the World, is famous for its casino resorts and associated entertainment. Established in 1905, Las Vegas officially became a city in 1911. At the close of the 20th century, Las Vegas was the most populous American city founded in that century (a distinction held by Chicago in the 19th century). The city's tolerance for various forms of adult entertainment earned it the title of Sin City, and this image has made Las Vegas a popular setting for films and television programs. There are numerous outdoor lighting displays on Fremont Street, as well as elsewhere in the city.
