In September 2005, the format of CNN's NewsNight was changed from 60 to 120 minutes to cover the unusually violent hurricane season. To help distribute some of the increased workload, Cooper was temporarily added as co-anchor to Aaron Brown. This arrangement was reported to have been made permanent the same month by the president of CNN's U. S. operations, Jonathan Klein, who has called Cooper "the anchorperson of the future. " Following the addition of Cooper, the ratings for NewsNight increased significantly; Klein remarked that "[Cooper's] name has been on the tip of everyone's tongue. " To further capitalize on this, Klein announced a major programming shakeup on November 2, 2005. Cooper's 360° program would be expanded to 2 hours and shifted into the 10 pm ET slot formerly held by NewsNight, with the third hour of Wolf Blitzer's The Situation Room filling in Cooper's former 7 pm ET slot. With "no options" left for him to host shows, Aaron Brown left CNN, ostensibly having "mutually agreed" with Jonathan Klein on the matter.
