Which New Year's Eve event in New York began in 1904 as a celebration for The New York Times' new headquarters?

The New Year's Eve event that began in 1904 to celebrate The New York Times' new headquarters was the Times Square celebration.

The newspaper moved into the Times Building, now One Times Square, in 1904. To celebrate the opening, publisher Adolph Ochs organized a New Year's Eve fireworks display at the building. The event drew such a large crowd that the city later restricted fireworks in the area for safety reasons.

The fireworks were replaced in 1907 by a descending illuminated ball. That change created the ball-drop tradition now associated with Times Square. The building's name also influenced the name of the surrounding district, which had previously been known as Longacre Square.

The 1904 event and the 1907 ball drop are related but not identical milestones. The former established the major public celebration at the site; the latter introduced the object and countdown ritual that became internationally famous.
