File on 4 Investigates

File on 4 Investigates has been publishing since 2010, and across the 16 years since has built a catalogue of 516 episodes. That works out to roughly 320 hours of audio in total. Releases follow a fortnightly cadence.

Episodes typically run thirty-five to sixty minutes — most land between 37 min and 37 min — and the run-time is fairly consistent across the catalogue. It is catalogued as a EN-language Society & Culture show.

The show is actively publishing — the most recent episode landed 3 days ago, with 35 episodes already out so far this year. Published by BBC.
