Unsolved Mysteries could probably be considered one of the first "reality" shows to really hit big, though I'm not comfortable with that categorization, because it was probably closer to news or Cops-like documentary than the reality shows we have now.

In fact, if you look at the old episodes, they seem almost quaint, even though they were talking about murders, abuductions, disappearances, curses, and UFO sightings. But there was a real non-sensationalist aura about the show, and you got the feeling they really wanted to get to the bottom of each case.

Now the show is coming back...to HBO!

Not only will the cable channel make new episodes of the show, they'll also re-edit older episodes. And this red-editing will include updates on older cases. One of the frustrating things about the old show was that you rarely saw an update to a case they covered, unless they caught someone or reunited siblings shortly after a show aired. No new host to replace the late Robert Stack has been announced yet.
