In which city did the first New Year's Eve ball drop take place in 1907?

The first New Year’s Eve ball drop took place in New York City in 1907.

The event occurred in Times Square, then commonly known as Longacre Square, at the top of the headquarters of The New York Times. Newspaper publisher Adolph Ochs arranged the illuminated ball as part of a New Year celebration after fireworks displays had been restricted.

The first ball was lowered on December 31, 1907, welcoming 1908. The spectacle quickly became an annual tradition, although the ball drop was suspended during 1942 and 1943 because wartime blackout rules prevented the usual illuminated celebration.

The answer is New York City rather than Times Square: Times Square is the specific location within the city. The event also should not be confused with later ball-drop celebrations modeled on the New York tradition.
