The Five Eyes has two types of information collection methods: the PRISM program and the Upstream collection system. The PRISM program gathers user information from technology firms such as Google, Apple and Microsoft, while the Upstream system gathers information directly from the communications of civilians via fiber cables and infrastructure as data flows past. The program's first disclosure to the public came in 1972 when a former NSA communications analyst reported to "Ramparts Magazine" that the NSA had developed technology that "could crack all Soviet codes". In 1988, Duncan Campbell revealed in the "New Statesman" the existence of ECHELON, an extension of the UKUSA Agreement on global signals intelligence . The story, 'Somebody's listening,' detailed how the eavesdropping operations were not only being employed in the interests of 'national security,' but were regularly abused for corporate espionage in the service of US business interests. The piece passed largely unnoticed outside of journalism circles.
