    On December 31, 1904, New Yorkers first celebrated New Year’s Eve in Times Square. About 200,000 people showed up for that first celebration. Today, more than a million people—mostly tourists—crowd the busy plaza every December 31.  
    The first Times Square celebrations were marked with fireworks displays. Safety concerns ended that tradition in 1907. That year, the New York Times, which originally sponsored the celebrations, began dropping a “time ball” signifying the new year. Time balls are an ancient signaling device used by mariners. A worker at a facility on land would drop a large metal ball perched atop a tall building at a specific time, allowing sailors to set their chronometers at sea. Time can be used to determine longitude, so time balls not only told sailors the time, they also allowed mariners to know their position and navigate successfully.  
    The first Times Square time ball was made of wood, metal, and lit with incandescent light bulbs. Today, the ball is made of metal, crystal, and lit by LEDs.
