Cityscape: Crazes

If you were around during the disco era, you’re more than likely familiar with the dance craze the Hustle. Like most dance crazes, the simple moves and catchy tune helped it -- to use a modern phrase -- go viral.

But, what is it about other things like sneakers, Apple products and even the Halal cart on 53rd Street  and 6th  Avenue in Manhattan that catch on, drawing lines that scale around several blocks?  On this week's Cityscape, we're talking about crazes, from the cronut to the Harlem Shake to the Greek yogurt craze.
