# Method

- Source: Podcast Index feed dump dated 2026-08-16, table `podcasts`, every row.
- True crime: `category1` equals "True Crime" (case-insensitive). Any slot: one of `category1` to `category10` does.
- Active: `newestItemPubdate` within 90 or 365 days before 2026-08-16.
- Start year: UTC year of `oldestItemPubdate`; 968 True Crime feeds have none.
- Host: domain of the feed URL, lowercased, platform aliases merged.
- Episodes: `episodeCount`, Buzzsprout excluded and feeds with 0 episodes excluded for the median.
