Pinball's outlaw years in New York City

Between 1940 and 1976, playing pinball in New York City was illegal. Mayor Fiorello LaGuardia banned it as a game of chance, associating it with the mafia. Despite public resistance, pinball machines went underground. During WWII, LaGuardia seized machines for scrap metal to support the war effort. It wasn't until 1976 that pinball was reclassified as a game of skill and legalized.
