Big Apple
Although the history of "Big Apple " was once thought a mystery, a clearer picture of the term's history has emerged due to the work of amateur etymologist Barry Popik, and Gerald Cohen of Missouri University of Science and Technology. A number of false theories had previously existed, including a claim that the term derived from a woman named Eve who ran a brothel in the city. This was subsequently exposed as a hoax.
Big Apple
Uses of the term abound elsewhere in the names of cultural products and events in or concerning New York, including the Big Apple Anime Fest, the Big Apple Theater Festival, Jess Teong's The Kid from the Big Apple and Kajagoogoo's Big Apple, and playful uses of the nickname have been seen, such as Patrick Downey's 2008 historical study of New York City's criminal underworld, entitled "Bad Seeds in the Big Apple."
