In the late 20th century, telecommunication and high technology industries employed many New Yorkers. New York City was especially successful at this transition. Entrepreneurs created many small companies, as industrial firms such as Polaroid withered. This success drew many young professionals into the still–dwindling cities. New York City was the exception and has continued to draw new residents. The energy of the city created attractions and new businesses. Some people believe that changes in policing created a less threatening environment; crime rates dropped, and urban development reduced urban decay.
