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.
Greeter
The first Greeter initiative was New York's Big Apple Greeters, founded by Lynn Brooks in 1992. It was hoped that the program, sponsored by Manhattan borough president Ruth Messinger, would improve New York's reputation as a "dangerous, expensive and overwhelming" place by letting tourists see it through the eyes of its residents. This idea soon spread to a variety of tourist destinations across the world.
