In what is one of the most heavily attended New Year's Eve events in the world, 500,000 regularly attend the New Year's Eve Ball drop in Times Square. Another 300 million TV viewers watch festivities from home. Some estimate that this New Year's Eve nearly a million people will be in Times Square to take part in the festivities
