New York

Why is New York known as the big apple ?

[Philtaz]

Isn't it because someone once said of it that everyone wants to take a bite?

Sorry to post another link but I think this gives a more detailed description - http://salwen.com/apple.html - but to summary it seem to be due to an early American prostitute called "Eve".

In the early 1920s, "apple" was used in reference to the many racing courses in and around New York City. Apple referred to the prizes being awarded for the races -- as these were important races, the rewards were substantial.

Based on the research of Barry Popik, the use of "Big Apple" to refer to New York City became clearer. Popik found that a writer for the New York Morning Telegraph, John Fitzgerald, referred to New York City's races "Around the Big Apple." It is rumored that Fitzgerald got the term from jockeys and trainers in New Orleans who aspired to race on New York City tracks, referring to the "Big Apple."

In the late 1920s and early 1930s, New York City's jazz musicians began referring to New York City as the "Big Apple." An old saying in show business was "There are many apples on the tree, but only one Big Apple." New York City being the premier place to perform was referred to as the Big Apple.

 

A 1971 campaign to increase tourism to New York City adopted the Big Apple as an officially recognized reference to New York City. The campaign featured red apples in an effort to lure visitors to New York City. It was hoped that the red apples would serve as a bright and cheery image of New York City, in contrast to the common belief that New York City was dark and dangerous. Since then, New York City has officially been The Big Apple.

In recognition of Fitzgerald, the corner of 54th & Broadway, where Fitzgerald lived for 30 years, was renamed "Big Apple Corner" in 1997.

Because everybody is tempted to go there?  Because it's rotten to the core?  Because it's fulla maggots?  (Only joking, by the way - I've been there and loved it).
