The Great Detectives of Old Time Radio

The Great Detectives of Old Time Radio launched in 2025 and has put out 392 episodes in the time since. That works out to roughly 220 hours of audio in total. Releases follow a near-daily cadence, with the show now in its 115th season.

Episodes typically run twenty to thirty-five minutes — most land between 33 min and 37 min — and the run-time is fairly consistent across the catalogue. None of the episodes are flagged explicit by the publisher. It is catalogued as a EN-US-language Arts show.

The show is actively publishing — the most recent episode landed yesterday, with 276 episodes already out so far this year. The busiest year was 2026, with 276 episodes published. Published by Adam Graham.
