BB:FOF was a one hour show. It would show five stories (known as "segments") that were inspired by actual events (supposedly) that were "Beyond Belief". Some would be fact, and some would be fiction. It would be revealed with segments were fact or fiction at the end of the show.
The show premiered on May 1, 1997 and was last aired on September 1, 2002. FOX originally was broadcasting the show, but Sci-Fi eventually took over. The last marathon of BB:FOF ever put on Sci-Fi was back in August of 2005.
Sometimes, BB:FOF is ended with a question mark. It would sometmes be known as: Beyond Belief: Fact or Fiction?
James Brolin was the original host, but Jonathon Frakes eventually replaced him.
