The idea of distributing property or other valuables by lot dates back to ancient times. The Old Testament instructs Moses to take a census of the people of Israel and divide their land by lot; Roman emperors gave away property and slaves by lottery at their Saturnalian feasts. The Continental Congress held a lottery to raise money for the American Revolution, and Benjamin Franklin sponsored an unsuccessful one in 1776 to pay for cannons to defend Philadelphia against the British. Privately organized lotteries were common in the United States until the early 1820s, when they were outlawed.

In modern times, state governments have argued that lotteries are a way to raise money without the burden of more direct taxation. They can provide a range of services, they say, and the public is willing to pay for them by buying lottery tickets. This arrangement worked well in the immediate post-World War II period, when states were able to expand their social safety nets while avoiding hefty taxes on middle-class and working-class residents.

When state legislatures authorize a lottery, they delegate the responsibility for running it to a special lottery division. The agency is responsible for selecting and licensing retailers, training employees of retailers to sell and redeem lottery tickets, establishing the prize structure, paying high-tier prizes and verifying that winning numbers are drawn in accordance with state law. It also manages promotional campaigns for the lottery, and makes sure that retailers and players comply with the laws of their respective states. The division also works with the media to publicize the lottery and encourage participation. It may also conduct audits of retail outlets that promote the lottery. In some cases, the state will contract with a private company to run the lottery. In other cases, it will use its own staff and resources. In the latter case, the private company typically pays a fee to the state for the right to advertise in its name.
