Which New York City building hosts the Times Square Ball drop?

The New York City building hosting the Times Square Ball drop is One Times Square.

One Times Square is a tall, narrow building at the intersection of Broadway and Seventh Avenue. It was originally constructed for the New York Times, whose move there helped give the surrounding area its name. The building's prominent position made its rooftop flagpole suitable for the first ball drop in 1907.

Although the ball drop is often described simply as a Times Square event, the ball is specifically lowered from One Times Square. The building has undergone changes in use and advertising displays over time, while its role in the annual ceremony has remained central.
