Who Wants to Be a Millionaire (ABC)

This iconic show -- which made household terms out of phrases like "Is that your final answer?" -- remains a staple in the modern game-show industry. After a three-year heyday in primetime starting in 1999 (during which it was broadcast as often as four nights a week), the show moved to daytime TV and adopted some new rules, imposing time limits for contestants’ answers and adding a fourth lifeline option that was earned when a player surpassed a designated monetary value. Other minor format changes have occurred through the years, serving to streamline and expedite the show.

No matter which versio you end up watching, Millionaire continues to entertain families -- and the good news is that there’s no reason to sweat sharing it with your tweens and teens. It’s fun to put your own grasp of trivia up against the contestants' as you watch at home, and you’ll probably learn something new each time you tune in. The only issue that adults might have with the content is the deliberate mention of sponsors like AT&T, Skype, and AOL, but in today’s commercialized media market, even these instances seem slight.
