The NSA collected telephone call records covering calls of most Americans on an ongoing basis. The Section 215 programme assembled metadata, including numbers, times, and duration, under recurring Foreign Intelligence Surveillance Court approvals. This particular collection did not record the spoken content of conversations.
The 2013 disclosures were followed by government confirmation and an official oversight investigation. In 2014, the Privacy and Civil Liberties Oversight Board concluded that Section 215 did not provide an adequate legal basis and recommended ending the programme. Bulk collection under this programme ended in November 2015.
A call record can be revealing without containing speech. Repeated contacts, timing and duration can expose relationships and routines across a population. The distinction between metadata and content is essential to understanding the programme’s actual reach, rather than minimising its privacy implications.
The oversight report provides a second layer beyond the initial disclosure. It asks whether the legal authority justified the collection and whether the programme contributed enough to support its claimed necessity. A technological capacity, a legal basis and an operational benefit are three different questions.

The transition changes the telephone-records arrangement.
Where the evidence stops.
Metadata is not audio. Do not conflate this ended programme with Section 702 content collection or suggest it continues unchanged today.
