Lottery is a gambling game that involves the drawing of numbers in order to win a prize. Although making decisions or determining fates through the casting of lots has a long history, the modern lottery began in 1776 when Benjamin Franklin sponsored a public lottery to raise funds for cannons for Philadelphia during the American Revolution. Lottery has since become an integral part of state government and has raised more than $80 billion in America alone.

Despite its popularity, lottery is not without its critics. Several studies have documented problem gambling among lottery players, and many people spend more than they can afford to lose. Additionally, lottery advertising focuses on the idea that winning the jackpot is easy and can improve your life dramatically. However, the majority of winners do not keep their entire jackpots and instead pay huge taxes that devalue the initial investment.

The most significant problem with lotteries is that they are run as businesses to maximize revenues. This approach inevitably puts them at cross-purposes with the public interest and creates conflicts of interest. In addition, lottery advertising frequently presents misleading information about odds of winning; inflates the value of a jackpot (which is often paid in annual installments over 20 years, with inflation and taxes eroding the value); and so on.

Moreover, lotteries are often run by political officials who do not have the full picture of the industry in front of them. Because of this, they are unable to prioritize the needs of the public and can be pushed by lobbyists to increase revenues.
