# Unsolved Mysteries

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, beginning on NBC on January 20, 1987, becoming 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.
After a six-year absence, the series was resurrected by Spike in 2007, and began airing on October 13, 2008. This new, revived version was hosted by Dennis Farina, who mainly tied together repackaged segments from the original episodes. Farina hosted 175 episodes before the series ended again on April 27, 2010. Cosgrove-Meurer Productions maintains a website for the show, featuring popular accounts and ongoing cold cases (murder or missing persons), with a link to an online form should a viewer have information on an unsolved crime. As of 2017, the show maintains a YouTube page where viewers can submit their own mysteries. If accepted, Unsolved Mysteries posts a video of the viewer describing the mystery. That same year, FilmRise acquired worldwide digital distribution rights to the series and announced its intent to release updated versions of its episodes. These shows are currently streaming on Amazon Prime, Tubi TV, and on its own dedicated channel on Pluto TV in the United States and the United Kingdom. Since February 2017, the Spike episodes have been officially posted on YouTube, split into eight seasons. In July 2017, the series began streaming on Hulu in the United States. Between February and March 2019, FilmRise began posting digitally restored and re-edited episodes, hosted by Stack, on YouTube.
On June 22, 2018, Terror Vision Records released the official soundtrack for the series. In 2017, the show's creators expressed interest in reviving the series. On January 18, 2019, Netflix picked up a reboot of the series which premiered on July 1, 2020. The first season of the reboot was split into two volumes containing six episodes each. In September 2022, Netflix announced that a third volume of new episodes would begin streaming in October 2022. In February 2024, it was announced that a fourth volume would begin streaming in 2024. It was confirmed that the fourth volume would begin streaming in July 2024. A fifth volume, consisting of four episodes, was announced on July 31, 2024. It began streaming in October the same year.

## Overview

Unsolved Mysteries used a documentary format to profile real-life mysteries and featured re-enactments of unsolved crimes, missing persons cases, conspiracy theories and unexplained paranormal phenomena (alien abductions, ghosts, UFOs, and "secret history" theories).
The concept was created in a series of three specials produced by John Cosgrove and Terry-Dunn Meurer, which were pitched to NBC in 1985 and shown in 1986 with the title, "Missing... Have You Seen This Person?" The success of the specials led Cosgrove and Meurer to broaden the series to include mysteries of all kinds.
The pilot of what eventually became Unsolved Mysteries was a special that aired on NBC on January 20, 1987, with Raymond Burr as host/narrator. Throughout the 1987–88 television season, six more specials aired, the first two hosted by Karl Malden and the final four by Robert Stack. Because of the incorporation of paranormal mysteries, NBC News disowned the series when it aired on the network and required that a disclaimer aired before each show clarify that it was "not a news broadcast."
In 1988, the show debuted as a weekly program on NBC. Ratings steadily dropped after the 1993–94 season. Until 2002, it was hosted by Stack. In its second season on CBS in 1999, Stack was joined by co-host Virginia Madsen. Episodes released between 1995 and 1997 featured journalist Keely Shaye Smith and television host Lu Hanessian as correspondents in the show's "phone center", where they provided updates on previous stories as information for "special bulletin" segments. A March 14, 1997, episode featured journalist Cathy Scott in the reenactment of rapper Tupac Shakur's 1996 unsolved murder. This broadcast was one week after the murder of Biggie Smalls. In 2002, the series was canceled by Lifetime. In 2008, television network Spike revived the series with Dennis Farina as its host; the Spike revival ended in 2010.
The show was known for its eerie theme song composed by Michael Boyd and Gary Remal Malkin, and for Stack's grim presence and ominous narration. The theme music was changed seven times, in 1993, 1995, 1997, 1999, 2001, 2008, and 2020. The 2020 version of the theme was arranged, performed, and recorded by West Dylan Thordson.

## Updates

Viewers were occasionally given updates on success stories, where suspects were brought to justice and loved ones were reunited.
The show itself has been credited for bringing increased attention to certain cases and thus allowing them to be solved. One episode featured a video of an arsonist filming an unidentified house being burned down while he was giving strange commentary. Once it had been featured on the show, viewers were able to identify the house involved, and two suspects were arrested.

## Broadcast history
### NBC (1987–1997)

The show first aired on NBC from 1987 to 1997. The pilot episode was hosted by actor Raymond Burr. Karl Malden and Robert Stack were also hired to host further specials. When the series became a full-fledged television program in 1988, Stack became the full-time host. Unsolved Mysteries was also one of the few prime-time shows of its era to appeal to fans of the supernatural and used effective special effects to enhance tales of the unexplained. In 1992, NBC aired a short-lived dramatized court show spin-off program called Final Appeal: From the Files of Unsolved Mysteries, also hosted by Stack. The premise of this program was to try to give the unjustly accused a final appeal for help, with the debut episode taking an in-depth look at the Jeffrey MacDonald case. The program was canceled after only a few episodes due to poor ratings.

### CBS (1997–1999)

The ratings for Unsolved Mysteries had been steadily declining ever since it was moved from its original Wednesday evening timeslot to Friday evenings in the fall of 1994. At the end of the 1996–97 season, it was canceled by NBC. Upon the cancelation from NBC, CBS picked up the series for a tenth season. The first episode aired in November 1997 as an Unsolved Mysteries special. When CBS canceled its Block Party line-up in the spring of 1998, the network moved the show to its Friday 9:00 pm timeslot. During the show's run on CBS, the series was limited to only six-episode seasons, and was airing only on a sporadic schedule. Reruns aired during the summer of 1998 with heavy promotion of the return of the NFL on CBS with the upcoming 1998 NFL season. When the series returned for its abbreviated 11th season in the spring of 1999, Stack was joined by actress Virginia Madsen for hosting duties in an attempt to boost its female audience. The effort failed, and CBS canceled the show soon afterwards. Later cable reruns of segments originally narrated by Madsen were re-dubbed with Stack's voice.

### Lifetime (2001–2002)

Lifetime Television, which had been airing re-runs of the NBC episodes since the early 1990s, had ordered a two-season run of new episodes which began airing in 2001. Consisting of a mixture of new and old cases, these episodes were produced between 2001 and 2002, and usually aired on weekdays between 11 a.m. and 3 p.m. The program ceased producing new episodes when Stack was diagnosed with prostate cancer in late 2002. He died of heart failure in May 2003.
After Stack's death, old episodes continued to run in syndication on several television networks in the U.S., Canada, and Australia. During some shows, callers gave tips to the telecenter. When the show was in active production, the toll free number was displayed on the bottom of the screen below the title logo at the end of each segment. When the show left active production following Stack's death and went into reruns, the number was removed and replaced with a P.O. box address.

### Spike TV (2008–2010)

According to Broadcasting & Cable, in 2007, HBO Distribution announced plans to bring back Unsolved Mysteries when the cable channel Lifetime's contract expired in 2008. The show featured a new set, a new logo, new music, and updates on old cases. In addition, actor Dennis Farina became the new host, as Stack had died five years earlier. The show debuted on Spike on October 13, 2008.
This repackaged series run was criticized by fans for its presentation of past cases only, with no new case segments being produced. The existing segments were also edited to be shorter so the show could be expanded to present five cases in an hour rather than the four of the original series. Because the majority of the cases were now between 20 and 40 years old, the re-edited segments usually did not reference the years in which the events presented originally occurred. When updates for solved cases aired, Dennis Farina's voiceover would refer to cases "in a recent broadcast...", when the case may have already been solved during the show's original run or during the series' hiatus from 2002 onward. Unsolved Mysteries ended its run on Spike on April 27, 2010.

### Netflix (2020–present)

A 12-part reboot was announced by Deadline Hollywood on January 18, 2019. The series is being "refreshed" by Stranger Things executive producer Shawn Levy and his company 21 Laps Entertainment along with Cosgrove-Meurer Productions and Netflix. Cosgrove and Meurer are showrunners for the series, with Levy and Josh Barry being executive producers. Robert Wise is a co-executive producer, along with showrunner Dunn Meurer. Each episode focuses on a single mystery. Cosgrove stated that the reboot would be "pure documentary style" and would have no host or narrator; however, an image of longtime host Robert Stack can be seen in the title sequence for each episode as an homage to his impact on the show. The first six episodes of the new season became available to stream starting July 1, 2020. In August 2020, it was reported that 13.7% of subscribers had watched the series over its first month. On September 1, 2021, Netflix formally announced that it had ordered an additional season of the series set to launch in the summer of 2022. On September 6, 2022, Netflix announced a third volume of nine new episodes, billed as a "three-night event", would begin streaming October 18, October 25, and November 1, 2022. Netflix announced in February 2024 that a fourth volume of episodes would air sometime that same year. On June 20, 2024, it was announced that the fourth volume would begin streaming on July 31, 2024. A fifth volume consisting of 4 episodes premiered in October 2024.
