I think Jeff Probst if IMO, is the first and the only original reality tv show host.
I couldn't at all imagine Survivor without him.
Because he has to be a teacher, coach, drill instructor, detective, comic relief, as well as host & producer. All rolled-up into one.
The show wouldn't be the same without him. Because I am glad he is staying on at least until the seventeenth edition.
Of the GRANDADDY of reality tv shows.
No wonder more than sixty million tuned into the show or one of the reasons is him.
