The series premiere of Fox’s heavily hyped boxing reality show, The Next Great Champ, was not the mainstream success the network was hoping for. The show failed to capture the highest Nielsen ratings for its time slot, Tuesday at 9:00 pm.  According to E! Online, preliminary ratings show that The Next Great Champ drew considerably less viewers than another reality show, Big Brother 5, and an adult cartoon, Father Of The Pride, both of which aired at the same time.   While Big Brother 5 averaged 9.8 million viewers and Father Of the Pride averaged 9.6 million, The Next Great Champ drew just 5.2 million viewers, a figure that is only 1.6 million higher than a two-year-old rerun of Celebrity Boxing 2 garnered on Fox last month. Richard Schaefer, CEO of Golden Boy Promotions, the show's co-producer, put a good spin on the ratings numbers. "While in the world of reality television and its continued race for better ratings the network expectations might have been higher, we have to realize that 5.2 million people watching a boxing related show is without question a success for the sport of boxing," said Schaefer in a statement issued today.
