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.
Time in New York
The state of New York uses the Eastern Time Zone (UTC-5) with DST (UTC-4). Because the largest city in the state, New York City, is the largest city in the United States, and because the Eastern Time Zone is used in the nation's capital, Washington, D.C., in addition to the fact that a majority of the nation's population is in that time zone, Eastern Time is the most commonly used time zone for television scheduling. Therefore, if a program airs at 7:00 PM Eastern Time, the network will usually advertise it by saying "Tonight at 7, 6 Central", or just "Tonight at 7".
