A lottery is a competition based on chance in which numbered tickets are sold and prizes, usually cash or goods, are awarded to the holders. A lottery is typically run by a government and is designed to raise money for a particular public purpose. In the United States, state governments have sole authority to operate a lottery and profits from lotteries are used only for the benefit of the state government. Most lotteries are monopolies that prohibit competitors from entering the market. As of August 2004 there were forty-three operating state lotteries in the United States and most adults living in a lottery-sanctioned state can purchase a ticket.
A common element of all lotteries is the distribution of tickets and stakes to retailers (often referred to as sellers) for sale to players. Most lotteries sell their tickets in convenience stores, although some are sold over the Internet or by mail. Lottery officials also often promote games through television and radio commercials and newspaper advertisements.
Many state lotteries develop a specific constituency of retail buyers who are particularly loyal to their brand. In some cases, lottery retailers form exclusive partnerships with the state’s lotteries to help maximize sales and revenue.
Lotteries are ancient in origin. The practice of drawing lots to determine property ownership or other rights is recorded in biblical accounts and later became a staple of early European colonial-era public finance, with lottery proceeds being used for town fortifications, wars, college buildings, and other public-works projects. Today, lottery participation continues to be widespread throughout the country. It is generally agreed that the bulk of lottery players and revenues come from middle-income neighborhoods, whereas participants in lower-income neighborhoods are significantly less likely to play.
