This entry is a bit different from the others on the list. It’s more about multiple networks covering multiple aspects of Hurricane Katrina, although you'd be hard-pressed to find any live footage that came either during the storm or in its immediate aftermath that wasn’t absolutely shocking. Americans never thought they would see one of their most recognizable cities reduced to a true disaster zone, and those early aerial shots after the storm helped the country come to terms with the scope of the event.

Live footage of dead bodies, submerged buildings, and a shattered population littered networks for days. Plus, The Weather Channel literally braved the storm to bring us live coverage of Katrina as it happened, which brought the sheer terror and utter craziness of the storm into America’s living rooms.
