Lottery is a system of distribution of prizes in which a person pays for an opportunity to win, and if he or she wins, a prize is awarded. Lottery is a form of gambling, and the prizes can range from cash to goods or services. There are several different formats for a lottery, but each requires the three elements of consideration (payment by the player), chance and prize. Federal laws prohibit the sale of lottery tickets by mail or over the telephone, and federal regulations also restrict promotional activity in interstate commerce.
The casting of lots for determining fates and distributing property has a long history in human culture, with the Old Testament containing many examples of such lotteries. A more recent use of lotteries for material gain can be traced to the Roman emperors, who used them as a common dinner entertainment, called an apophoreta, in which pieces of wood bearing symbols were distributed among guests and then drawn for prizes that each took home. In modern times, state lotteries have followed remarkably similar paths: the state legislates a monopoly for itself; establishes a public agency or corporation to run the lottery (as opposed to licensing private firms in return for a share of the profits); starts operations with a modest number of relatively simple games; and, because of constant pressure for additional revenues, progressively expands the lottery with new games and a more aggressive promotion campaign.
Lotteries are popular with the general public, and studies show that they are one of the most popular forms of gambling. They are also a powerful revenue source for state governments, which are increasingly dependent on their proceeds for funding. Despite the broad popularity of lotteries, there is considerable debate over whether they promote gambling addiction and other problems. Lottery critics argue that the advertising used to promote lotteries glamorizes the gambling experience and encourages people to spend more money than they can afford, especially by presenting unrealistically high jackpot prize amounts. In addition, critics point out that the distribution of lottery proceeds is skewed by income and that low-income people participate in the lottery at much lower rates than do higher-income citizens.
Advocates of the lottery argue that the proceeds are earmarked for specific purposes and that the public benefits outweigh the costs. However, these arguments are based on assumptions that have been proven false in numerous studies. In reality, lotteries primarily serve the interests of convenience store operators; lottery suppliers; state legislators (who benefit from the enormous campaign contributions made by lottery supplier lobbyists); teachers (in states where lottery proceeds are earmarked for education); and others with a direct financial interest in the success of the lottery. These special interests have a powerful influence on the way in which the lottery is promoted and managed. The resulting imbalance between public benefits and private costs has created a complex set of problems that are difficult to resolve. The solution is not likely to be found in the continued expansion of the lottery, but rather in the development of more thoughtful and effective policies for regulating this popular form of gambling.
