Which New York City building was the original home of the Times Square New Year's Eve ball?

One Times Square was the original home of the Times Square New Year's Eve ball.

The building, formerly known as the New York Times Building, hosted the first ball drop in 1907. The newspaper's owner, Adolph Ochs, had organized a fireworks celebration for the opening of the Times' new headquarters, but a ball provided a reusable and visually striking alternative after fireworks were restricted.

The first ball was made of iron and wood, measured about five feet in diameter, and was lit with electric lamps. Later versions changed in size, materials, and lighting technology. The current ball is much larger and uses LED illumination and crystal panels.

The building stands at the northern end of Times Square, where Broadway and Seventh Avenue meet. The annual event is named for the square, not for the Empire State Building or Rockefeller Center, both of which are also famous New York landmarks and host other celebrations or broadcasts.
