"Survivor" host Jeff Probst on the evolution of TV's longest-running reality competition

Jeff Probst is returning as the face of "Survivor" after 24 years and almost 700 episodes of the groundbreaking television reality competition series, which is preparing to launch its 48th season.

"I remember how excited I was," Probst said of the show's early days. "We didn't know it was going to be a hit, but we knew it was unique."

Premiering in 2000, "Survivor" has kept Probst at the helm throughout its run. The show's longevity, he believes, stems from its authenticity.
