The lottery is a popular source of entertainment and funds in many states. It is also a source of controversy over its regressive impact on low-income people, problems of compulsive gambling, and other issues of public policy. But, since New Hampshire introduced the modern state lottery in 1964, there has been remarkably little variation among states in the way that they have developed lotteries and operated them.

State lotteries typically start with a monopoly granted to the state itself; establish an independent agency or public corporation to run the operation (as opposed to licensing a private firm in exchange for a share of the profits); begin operations with a modest number of relatively simple games; and, because of pressures to expand revenues, gradually increase the size and complexity of the offerings. The result is that most state lotteries have become highly specialized, with few or no other business activities to distract them from the need to increase revenue.

Lottery officials often emphasize the benefits of a lottery as a means to promote economic development, especially in rural and suburban areas. They also highlight the importance of supporting education and social welfare programs. The message, however, tends to ignore or obscure the regressive impact of lotteries on lower-income groups. In addition, the message that the lottery is fun and easy to play obscures the fact that for some individuals it becomes an expensive habit that consumes a large portion of their incomes.

In recent years, the popularity of lotteries has increased with the introduction of instant tickets and online games. Although it is impossible to predict the future, the current momentum appears likely to continue. However, there are important issues that need to be addressed as the lottery continues to evolve and grow.

The practice of drawing lots to determine property distribution dates back at least to ancient times. The Old Testament has numerous references to the Lord giving land and other possessions by lot. Lotteries were also common during the Roman Empire as a form of entertainment at parties or during Saturnalian feasts, where winners would be awarded with slaves or other valuable goods.

After World War II, a number of states began to adopt lotteries as a painless method of taxation. Lotteries helped finance a broad array of state services and provided an alternative to more onerous taxes on working and middle classes. Initially, these lotteries were widely viewed as a worthwhile investment in the long term. But, with increasing pressure to generate more and more revenues, the reliance on lotteries for state revenues has become increasingly problematic.

While the number of states offering lotteries has expanded rapidly, there are still significant differences in how they operate and in their societal impacts. In general, states with larger social safety nets and higher poverty rates have tended to develop more robust lotteries than those with less generous taxation systems. This is in part because, in those states, a greater percentage of adults play the lotteries.
