In the 1907 Times Square Ball's first New Year's Eve drop, which New York newspaper owned the building?

The New York Times owned the building connected with the first Times Square Ball drop.

The newspaper moved its headquarters to a new skyscraper in Manhattan in 1904. The building was originally known as the Times Building and stood near Longacre Square. A campaign around the new headquarters helped lead to the area being renamed Times Square.

For the celebration welcoming 1908, Times publisher Adolph Ochs arranged a midnight fireworks display on the building. After New York City prohibited fireworks, the newspaper introduced a large illuminated ball lowered from the flagpole. That ball descended at midnight on December 31, 1907, beginning the tradition now known as the Times Square Ball drop.

The newspaper later moved elsewhere, and the building became One Times Square. The ball-drop ceremony remained associated with the location even after the original newspaper headquarters had changed function. The newspaper's name is therefore the New York Times, not a broadcaster or a New York city agency.
