two million people overflowed Times Square, flowing from Sixth Avenue to Eighth Avenue and back on Broadway and Seventh Avenue to 59th Street, making it the largest gathering in Times Square since August 1945 during celebrations marking the end of World War II. On December 31, 1907, a ball signifying New Year's Day was first dropped at Times Square, and the Square has held the main New Year's celebration in New York City ever since. On that night, hundreds of thousands of people congregate to watch the Waterford Crystal ball being lowered on a pole atop the building, marking the start of the new year. It replaced a lavish fireworks display from the top of the building that was held from 1904 to 1906 but stopped by city officials because of the danger of fire. Beginning in 1908, and for more than eighty years thereafter, Times Square sign maker Artkraft Strauss was responsible for the ball-lowering. During World War II, a minute of silence, followed by a recording of church bells pealing, replaced the ball drop because of wartime blackout restrictions. Today, Countdown Entertainment and One Times Square handle the New Year's Eve event in conjunction with the Times Square Alliance. A new energy-efficient LED ball debuted for the arrival of 2008, which was the centennial of the Times Square ball drop. The 2008–09 ball is larger and has become a permanent installation as a year-round attraction, being used for celebrations on days such as Valentine's Day and Halloween. The New Year's Eve celebrations are usually overseen by thousands of police officers. Aluminum barriers are erected to accommodate spectators; for the 2020 celebration, attended by a million people, barriers were erected from 38th to 59th Street and from Sixth to Eighth Avenue. Typically, the celebrations create large amounts of waste. The New York City Department of Sanitation estimated that by 8 a.m. on New Year's Day 2014, it had cleared over of trash from the New Year's celebration, using 190 workers from their crews and the Times Square Alliance. Impact of COVID-19 The onset of the COVID-19 pandemic in New York City during 2020 reduced the number of people traveling to Times Square. About 108,000 pedestrians visited Times Square each day in late 2020 compared to the 380,000 before the pandemic. From March to October 2020, 26 of the area's 46 hotels closed, as well as 39 of 151 stores
