Gizmodo:

Times Square is one big, busy machine. Powered by American ingenuity and more than a few megawatts of electricity, these six square blocks stay bright 24 hours a day, seven days a week. You’ve seen Times Square in movies and on TV a million times.

A lot of you have probably seen it in real life, teeming with chaos and glowing with capitalism. But how exactly does all that work? The shops and restaurants are one thing, but what exactly makes Times Square such a functional, perpetual spectacle?

The amount of technology, both digital and analog, involved in putting on the “show” that is Times Square is mind boggling. Even more so in Tokyo’s Ginza District.
