See a transforming Times Square, from the 1910s through today

One of New York City's biggest shindigs is set to go down tonight in Times Square, as approximately one million people descend on Midtown to see a 12,000-pound ball covered in Waterford Crystal drop, ringing in 2018.

The tradition has been going for more than 100 years, and has only gotten bigger with time, both in size (only 200,000 people attended the first bash, intended to celebrate the opening of the New York Times's headquarters, in 1904) and scope.

But how has Times Square changed in that century-plus? A lot, if a look through the Museum of the City of New York's photo collection is any indication. Take a look at some of the most fascinating photos of the neighborhood, showing Times Square from the early 20th century all the way through the present.
