Mass surveillance in the United States
After the First World War and the Second World War, the surveillance continued, by programs such as the Black Chamber and Project SHAMROCK. The formation and growth of federal law-enforcement and intelligence agencies such as the FBI, CIA, and NSA helped surveillance, such as the COINTELPRO projects from 1956–1971.
A series of media reports in 2013 revealed more recent programs and techniques employed by the US intelligence community. Advances in computer and information technology allow the creation of huge national databases that facilitate mass surveillance in the United States.
