After just four episodes, Fox is demoting its boxing reality show, "The Next Great Champ" to its cable channel, Fox Sports Network.  The series, which features unknown boxers vying for cash prizes and what is claimed to be a championship fight, will be aired on Sundays at 6 pm starting on October 17 with rebroadcasts on Sundays at midnight and Monday at 9 pm.  Fans interetsed in catching up on missed episodes can tune into Fox Sports this Sunday at 5 pm for a four-hour rerun marathon.  Although critics say the quality of the show suffered because Fox raced to beat a competing boxing reality show to the airwaves, Fox blamed the ratings failure on the limited appeal of the sport.  "Unfortunately, despite its loyal core audience, the underlying boxing theme of the series has proved too narrow for us.  In the end, it belongs on an outlet better suited to serve the boxing fan," said Gail Berman, Fox's president of entertainment. According to the reality tv website zap2it.com, the switch will mean a drop in viewership from 4.7 million per week to less than one million per week.  Fox, however, has shown enthusiasm for boxing in other ways, such as airing James Toney-Rydell Booker as part of a recent edition of the Best Damn Sports Show Period. Fox's competition, The Contender, produced by reality tv genius Mark Burnett, is scheduled to air on NBC later this fall and involves more-established boxers such as Boxingtalk's #28 junior middleweight, Peter Manfredo. Boxingtalk is also investigating the progress of The Contender, and we hope to have some inside information on this show in the coming days.
