**Conversations with a Killer: The Charles Manson Tapes** surged to the top of global Netflix charts immediately after its August 12 release as the final installment in Joe Berlinger’s acclaimed true-crime series, capitalizing on enduring public fascination with the Manson story through newly released prison recordings and archival material. Strong early viewership in the true-crime genre, which frequently produces rapid chart climbs, has solidified trader consensus around its #2 positioning behind a dominant title like The Last House. Historical patterns show such documentaries often sustain momentum for one to two weeks post-debut before audience interest tapers. An upset remains possible if a late-week surge from returning seasons such as My Life With the Walter Boys or Tires overtakes it in cumulative global hours viewed, or if the series experiences a steeper-than-expected drop-off in engagement before the weekly tracking period closes.
