Atlantic City, sometimes referred to by its initials A.C., is a Jersey Shore seaside resort city in Atlantic County, in the U.S. state of New Jersey. Located in South Jersey on Absecon Island, the city is prominently known as the "Las Vegas of the East Coast." Known for its taxis, casinos, nightlife, boardwalk, and Atlantic Ocean beaches and coastline, Atlantic City inspired the U.S. version of the board game Monopoly, which uses various Atlantic City street names and destinations in the game. New Jersey voters legalized casino gambling in Atlantic City in 1976, and the first casino opened two years later. From 1921 to 2004, Atlantic City hosted the Miss America pageant, which later returned to the city from 2013 to 2018.
