A lottery is a form of gambling in which numbers are drawn to determine prizes. The casting of lots for decisions and fates has a long history (Nero was a big fan) and is attested to throughout the Bible, although lotteries as a form of commercialized gambling are more recent. The first modern state-run lotteries were established in the mid-twentieth century as states searched for ways to raise money without triggering tax revolt among their electorates.
The most basic element of a lottery is the existence of a mechanism for recording identities, amounts staked, and the number or symbols chosen by each bettor. This may be as simple as a ticket on which the bettor writes his name, or it might involve a system whereby a bettor buys a numbered receipt that is deposited with the lottery organization for shuffling and selection in the drawing. Some modern lotteries use a computer system to record the bettors’ entries.
When a lottery is run as a business with the goal of maximizing revenues, its advertising necessarily focuses on persuading target groups to spend their money. This is at cross-purposes with public interest, because it inevitably promotes gambling and can lead to problems such as poverty and problem gambling.
Early lotteries drew on the tradition of private clubs and charitable institutions to sell tickets, often with a tethered prize such as an apartment building or a hospital. In the United States, some of the nation’s first church buildings and elite universities owe their creation to lottery funds. As state budget crises accelerated in the late twentieth century, however, a new group of advocates appeared on the scene. They argued that because people were going to gamble anyway, the government might as well take the profits.
