Who Wants to be a Millionaire?

Correctly answering 14 multiple-choice questions could net contestants $1 million on a half-hour quiz show that's had a long run since its adaptation from the Brit show with the same name. Its format has evolved, but the basics remain: Answer trivia questions to win what could be very big bucks. Safety nets along the way guarantee sums that can't be lost once a contestant reaches certain thresholds -- and players can quit any time, but going for the million carries the risk of losing hundreds of thousands with one wrong answer. Contestants get "lifelines" to help reach the top.
