From World War II until the creation of DIA in 1961, the three Military Departments collected, produced and distributed their intelligence for individual use. This turned out to be duplicative, costly, and ineffective as each department provided their own, often conflicting estimates to the Secretary of Defense and other Federal agencies. While the Defense Reorganization Act of 1958 aimed to correct these deficiencies, the intelligence responsibilities remained unclear, the coordination was poor and the results fell short of national reliability and focus. As a result of this poor organization, President Dwight D. Eisenhower appointed the Joint Study Group in 1960 to find better ways for organizing the nation's military intelligence activities.
