IAC's new headquartersSIAC's new headquartersSThe array of snacks at IAC's new headquarters — a spectacularly curvaceous Manhattan skyscraper designed by starchitect Frank Gehry — has nothing on the assortment at the Googleplex. But Barry Diller's internet conglomerate, which owns Ticketmaster and Ask among other properties, does offer 20 varieties of coffee to employees, and plenty of candy-colored flat surfaces in the restrooms. The free snacks at the Googleplex are blamed for the weight gain suffered by many new employees at Mountain View; the search giant's New York rival prefers its staff highly stimulated, and Manhattan-skinny. Below, a video tour of IAC's new building.
