CNN was displaying electoral results via colored lighting at the top of the Empire State building in New York.
«As each state is projected by CNN and electoral votes are allocated to the candidates, a vertical LED-illuminated ‘meter’ located atop the spire of the building will display CNN’s running tally of the race to 270,» the network explained.
Later, «when CNN projects a winner of the presidential election, the tower lights of the Empire State Building will change color to all-blue or to all-red.»
