“Visit at night, enjoy the billboards and the joyful atmosphere” was the title of a recent Tripadvisor review of New York’s Times Square.  Insider gets peeved when he hears city politicians calling billboards pollution.  Billboards promote the health of local businesses and create buzz and energy downtown.  If you doubt this visit Times Square or take a look at the Times Square website.  Remove the billboards from Times Square you would also remove the energy and crowds.
