Extra Challenge is a Philippine reality show developed by GMA News and Public Affairs which premiered in 1999. As a reality competition, Extra Challenge features celebrities pitted against each other in several challenges. The show is patterned after American reality-based series, such as Survivor, The Amazing Race, and Fear Factor; Extra Challenge, however, offers a distinctly Filipino style to entice and entertain local viewers as it fuses the trends of the reality show into a single program. Majority of the contestants featured are celebrities, contrasting the standard of their American counterparts. Another deviation is that the hosts themselves initiate or participate in the challenges.
