New York City is known as the Big Apple.
The nickname "Big Apple" for New York City is widely recognized and used. Its origin is attributed to a variety of sources, with one popular explanation relating to horse racing. In the early 20th century, a sportswriter named John J. Fitz Gerald used the term to refer to New York City's racetracks, considered the most important venues ("the big apple") in the sport. The term gained broader popularity in the 1920s and was revived in the 1970s through a tourism campaign.
