When does Gameshow Marathon return?

Gameshow Marathon (stylized as Game$how Marathon) is an American television program which aired on CBS from May 31 to June 29, 2006. It is based on the United Kingdom series Ant & Dec's Gameshow Marathon. The show features contestants competing in some of television's most popular game shows in a single-elimination format until an ultimate winner is found.
The seven-part game show tournament featured celebrity contestants Lance Bass, Paige Davis, Tim Meadows, Kathy Najimy, Leslie Nielsen, and Brande Roderick. The series used replicas of each show's original set, or in the case of The Price Is Right, actual props from the series currently airing.
