The casting of lots to determine decisions and fates is as old as humanity, with dozens of examples in the Bible. The lottery as a vehicle to distribute property or other material benefits, however, is much more recent. The Continental Congress held a lottery to raise funds for the American Revolution, and state lotteries were popular in England and the United States. Private lotteries became a common method for commercial promotions and for giving away valuable products and properties, as well as slaves and other assets.
In the modern era, lotteries are established by statute and run by government agencies or public corporations rather than licensed to private firms in return for a portion of the revenues. They begin with modest prizes and a relatively small number of games, and then gradually expand their offerings in response to market pressures. A percentage of the proceeds is deducted for organizational costs and profit, and the remaining pool is used to award the prizes. The decision is usually made whether to offer a few large prizes or many smaller ones.
Lotteries are generally regarded as painless forms of taxation and have a broad popular appeal. Despite their popularity, there are some serious questions about whether governments should be in the business of promoting gambling, especially since it is known to promote addictive behavior. Critics also argue that lotteries encourage illegal gambling, serve as a regressive tax on lower-income groups, and contribute to other vices.
