There is a long-running syndicated TV show called Missing. It is a half-hour series that profiles missing persons and offers safety tips. Missing (not to be confused with Missing: Reward) is hosted by Alex Paen. It is obviously made on a low budget, as it looks like a half-hour infomercial. Of all the public service shows that have aired in first-run syndication over the the years, Missing is the longest running one. It debuted in 2003 and is currently in its 16th year on the air. It has successfully led to the recovery of many missing people.
Missing airs on Saturdays on the Escape channel. Check your local listings to see if it is on a station in your area.
