The practice, which the bureau says is vital to counterterrorism efforts, casts a much wider net than previously disclosed, newly released documents show.

The F.B.I. has used secret subpoenas to obtain personal data from far more companies than previously disclosed, newly released documents show.

The requests, which the F.B.I. says are critical to its counter- terrorism efforts, have raised privacy concerns for years but have been associated mainly with tech companies.
