Season 1 of Who Wants to Be a Millionaire premiered on April 8, 2020.

In celebration of the 20th anniversary of "Who Wants To Be A Millionaire," Jimmy Kimmel steps into prime time as host of a special run of episodes featuring celebrity contestants playing for charity.

Season 2 of Who Wants to Be a Millionaire premiered on October 18, 2020.

Hosted by late-night's Jimmy Kimmel, this season will feature both celebrity contestants playing for the charity of their choice and frontline heroes trying their hand at a $1 million prize. In addition to lifelines "Ask the Host," "50/50" and "Phone a Friend," contestants playing on "Millionaire" can invite an expert guest to help them answer questions. It could be a relative, a beloved teacher or a famed trivia expert – anyone they want – to help them win as much money as they can.

Season 3 of Who Wants to Be a Millionaire premiered on July 10, 2024.

In a first-time twist, the new season will feature pairs of celebrity contestants playing together in the hopes of winning $1 million for the charity of their choice.
