Unsolved Mysteries
American true crime television series

Unsolved Mysteries is an American mystery documentary television series, created by John Cosgrove and Terry Dunn Meurer. Documenting cold cases and paranormal phenomena, it began as a series of seven specials presented by Raymond Burr, Karl Malden, and Robert Stack, which aired on NBC beginning on January 20, 1987. It became a full-fledged series on October 5, 1988, hosted by Stack. After nine seasons on NBC, the series moved to CBS for its 10th season on November 13, 1997. After adding Virginia Madsen as a co-host during season 11 failed to boost slipping ratings, CBS canceled the series after only a two-season, 12-episode run, on June 11, 1999. The series was revived by Lifetime in 2000, with season 12 beginning on July 2, 2001. Unsolved Mysteries aired 103 episodes on Lifetime, before ending on September 20, 2002, an end that coincided with Stack's illness and eventual death.

Why this record matters
“Unsolved Mysteries” is worth following because a concise public description often conceals a longer documentary argument. Here, Unsolved, Mysteries and American provides the most credible route into that argument.
Attribution, date and provenance are strongest when supported by the original work, a catalogue record and documented transmission. The source revision retrieved here is dated Sep 24, 2026. The first chronological checks are 1987, 1988, 1997 and 1999.
Rights, attribution and provenance may remain disputed even when a general reference summary presents a stable account. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
