After being on the air for more than three decades, the essential format of this show hasn't changed: Get an A-list guest host (or reasonable facsimile) and throw him or her into sketches with the ensemble players, which have included such heavy hitters as Will Ferrell, Jimmy Fallon, Tina Fey, Amy Poehler, Kristen Wiig, Jane Curtin, John Belushi, Chris Rock, Eddie Murphy, Chevy Chase, Bill Murray and Mike Myers. Each week's show also offers two musical numbers from someone at, or aspiring to reach, the top of the charts.

Offbeat games and bizarre challenges are the foundation for the on-the-spot comedy created in this new breed of game show. The contestants, a roster of comedians that includes Alex Borstein, Ben Garant, Thomas Lennon, Bobby Moynihan, Kumail Nanjiani and Nicole Parker, play games such as "Top This Lie," where they must out-fib host Kurt Braunohler in a rapid-fire succession of untruths, and "Wordy and the Tramp," where they provide answers to a series of disconnected questions while they and the host bounce on trampolines. The players are also challenged to -- among many other wacky tasks -- invent new sins, break harsh news to children, compose and sing original songs about grandmothers, and decide what mankind will evolve into next.

The world's talented yet undiscovered performers -- singers, dancers, magicians, comedians and more -- appear before celebrity judges as they compete to win a life-changing million-dollar prize, as well as viewers' hearts.

Professional dancers pair with celebrities to train and compete in ballroom dancing, receiving guidance from of a panel of experts along the way.

"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." The two highest winners of that round advance to the final, where prizes could be cars or roomsful of furniture. A trio of models presents the prizes.
