Where did that word come from?

You have to be of a certain age to remember the 1960 film "La Dolce Vita", which was an exploration of, and possibly an indictment of the hedonistic life-style of the "beautiful people" of Rome of the time. One of the minor characters is a photographer called Paparazzo (I don't think we ever know his first name) who makes his living by taking candid - and if possible, compromising - photos of celebrities to sell to the gutter press. His name very quickly became synonymous with that type of photographer and, being Italian, when there was more than one of them you used the plural - paparazzi.
