Times Square

On New Year's Eve one billion people will see (in some form) the ball drop in Times Square. Miley Cyrus will be there, Ryan Seacrest will too, and people across the country will have their TVs on when the clock strikes midnight. The Times Square spectacle is an annual tradition and while it has exploded in size, its roots stay pretty true to what the event looked like 100 years ago. 
1904 was the first year that New Year's Eve was officially celebrated in Times Square, and 100,000 people were in attendance. Prior to that, ringing in the New Year happened downtown at New York's Trinity Church near Wall Street. The move uptown, was motivated by the city's local newspaper.
