 At the time, FX's gimmick was the FX Apartment, which the hosts of various TV shows (such as "Breakfast Time" and "Sound FX") would use as a set.Also part of this gimmick was a very high level of interaction with viewers via their letters and e-mails, hence the TV show.Probst has commented that later in the show's run, he and the writers simply made up letters due to a drought of letters, and that none of the audience was ever able to tell the difference.
