Unsolved Mysteries is an American television program, hosted by Robert Stack from 1987 to 2002 and later by Dennis Farina starting in 2008. The show was broadcast first as specials in 1987, then as a regular series on NBC (1988–1997), CBS (1997–1999), Lifetime (2001–2002), and Spike (2008–2010). Lifetime once again airs the revived version of the series, but only in reruns.
Although the show is not in production, Cosgrove-Meurer Productions maintains a website for the show, featuring popular accounts and still unsolved crimes (murder or missing persons), with a link to an online form should a viewer have information on an unsolved crime.
Currently, the show maintains a YouTube page where viewers can submit their own mysteries. If accepted, Unsolved Mysteries will post a video of the viewer describing the mystery.
