"Come on down!" "The Price Is Right" -- hosted by Bob Barker until 2007 and Drew Carey thereafter -- features a wide variety of games and contests with the same basic challenge: Guess the prices of everyday (or not-quite-everyday) retail items. Four contestants, all of whom are seated in one of the wildest audiences in daytime game-show history, are called to the stage to play a preliminary pricing round. That winner joins the host on stage for one of more than 70 different pricing games. After three such games, the contestants spin a big wheel -- hoping to get as close to $1 as possible -- in the "Showcase Showdown." That's repeated in the second half of the show, and two highest winners of that round advance to the final, where prizes could be cars or roomsful of furniture. Models present the prizes.
