Instead of traditional -- and often expensive -- Christmas variety specials or movies, NBC plans to air episodes of its hit game shows Deal or No Deal, hosted by Howie Mandel, and 1 vs. 100, hosted by Bob Saget, on Christmas day, the network announced Thursday. (Both shows are produced by the U.S. subsidiary of Netherlands-based Endemol.) The network indicated that both shows will have Christmas themes and that the prizes awarded home viewers will be increased for this day only -- with the top prize on Deal being set at $100,000 and on 100 at $25,000.
