Lottery is a game in which tickets are drawn randomly to determine winners. The process is also used to fill vacancies on a team, select the best student among equally competing applicants for a degree program or place an advertisement on television. It is generally regarded as a form of gambling, and is subject to legal regulation.
Although the practice of making decisions and determining fates by casting lots has an ancient history (with numerous instances in the Bible), modern public lotteries have relatively recent origins. The earliest recorded public lottery, held during the reign of Augustus Caesar, raised funds for municipal repairs in Rome; the first to distribute prizes of money occurred in the Low Countries in the 15th century.
State governments now operate the majority of lotteries in the United States. Most of these lotteries are regulated by laws and delegated to a lottery board or commission. The commission oversees the selection and training of retailers, administers sales and redemption of tickets, helps retailers promote their games, pays high-tier prizes to players and assures that all players comply with state law and rules.
Lotteries have broad popular support. When states raise revenues with lotteries, the money can often be spent more freely than would otherwise be possible under a standard tax structure. Nevertheless, critics argue that state lotteries promote gambling behavior and are an inappropriate function for government at any level; they are widely considered to be a major source of addictive and illegal gambling and are characterized as a regressive form of taxation on lower-income groups.
