Created in 1947, the Central Intelligence Agency is an important part of the U.S.A's intelligence activities, and is currently playing a central role in the "war on terrorism." While the agency is often in the news and portrayed in television shows and films, it remains one of the most secretive and misunderstood organisations. This work provides an in-depth look into the Central Intelligence Agency and how its responsibilities affect American life. After a brief history of the agency, chapters describe its organisation, intelligence/counterintelligence, covert operations, controversies, key events, and notable people.
