What? Where? When? (1975)

I gathered 1,000 people to fight for $5,000,000, the LARGEST cash prize in TV history! We're also giving away a private island, Lamborghinis, and millions more in cash throughout the competition! Go watch to see the greatest show ever made!

America's favorite quiz show where contestants are presented with general knowledge clues in the form of answers, and must phrase their responses in question form.

Each Challenge pits numerous cast members from past seasons of reality shows against each other, dividing them into two separate teams according to different criteria, such as gender, which show they first appeared on, whether or not they're veterans or rookies on the show, etc. The two teams compete in numerous missions in order to win prizes and advance in the overall game.

The show where everything's made up and the points don't matter. Not a talk show, not a sitcom, not a game show, Whose Line Is It Anyway? is a completely unique concept to network television. Four talented actors perform completely unrehearsed skits and games in front of a studio audience. Host Drew Carey sets the scene, with contributions from the audience, but the actors rely completely on their quick wit and improvisational skills. It's genuinely improvised, so anything can happen - and often does.

This game show sees contestants solve word puzzles, similar to those used in Hangman, to win cash and prizes determined by spinning a giant carnival wheel.

"Come on down!" The Price Is Right features a wide variety of games and contests with the same basic challenge: Guess the prices of everyday (or not-quite-everyday) retail items. 

Human cannonballs! Human pinballs! Crashes, smashes and mud splashes! Twenty-four thrill-seekers will compete in the world's largest extreme obstacle course designed to provide the most spills, face plants and wipeouts ever seen on television.

Wizarding World fans put their Harry Potter knowledge to the test for the ultimate honor to be named House Cup champion.

A high-stakes competition series where twelve players work together in challenges to add money to a pot that only one of them will win at the end. Among the players is one person who has secretly been designated "the Mole" and tasked with sabotaging the group's money-making efforts. In the end, one player will outlast their competition and expose the Mole to win the prize pot.

The clock is ticking as contestants compete in games of lexical dexterity and numerical agility.
