A lottery is a form of gambling where participants purchase tickets for a chance to win a prize. Prizes may be cash or goods, and some lotteries are regulated by government authorities. Other lotteries are unregulated. In the United States, state-run lotteries provide a large portion of public education funding. Private business interests also operate lotteries.

Online lotteries have become increasingly popular, as people use computers to play from anywhere in the world.

In the mid-1990s, Internet lotteries began to appear, offering players the chance to participate in multi-national games for a small fee. The Internet allowed for faster transaction processing and greater reach, which led to an increase in players and a higher revenue stream for the lotteries. In 1998, the Internet Lottery Association was formed to promote standards and best practices for the industry. This helped to bolster confidence in the industry. The association was eventually succeeded by the National Lottery Commission, which continues to promote transparency and best practices in the industry.
