Private lotteries were legal in the United States in the early 1800s. In fact, a number of U.S. patents were granted on new types of lottery. In today's vernacular, these would be considered business method patents.
Before the advent of state-sponsored lotteries, many illegal lotteries thrived; for example, see Numbers game and Peter H. Matthews. The first modern state lottery in the U.S. was established in New Hampshire in 1964; today, lotteries are established in 42 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands; Arkansas voters approved a state lottery in the 2008 general election.
