Until April 2005, the DCI also served as de-facto Director of the Central Intelligence Agency and was often referred to colloquially as the "CIA Director." After the September 11, 2001 terrorist attacks on the United States and the subsequent investigation by the 9/11 Commission, a movement grew to re-organize the Intelligence Community. That movement prompted the creation, on April 21, 2005, of the Office of the Director of National Intelligence (DNI), in whose purview was the job portfolio that had been performed previously by the Director of Central Intelligence. The latter position then ceased to exist.
