Casino gambling -- once the domain of mobsters and hustlers -- has emerged as one of the most popular forms of adult entertainment. Since 1992, gaming revenues have doubled along with the number of states that have made it legal. Today, the gaming industry is no longer an outlaw business, but it is a national economic force with substantial political muscle. FRONTLINE chronicles how America's gaming industry has gone legit and examines the evolution of its political influence. The film also explores the astonishing growth of Indian gaming and the surprising role governments have played in promoting and legitimizing gambling.
