The American 'Who Wants to Be a Millionaire?' redefined the quiz show
The show was already a success in the United Kingdom when it was adapted for the US to boost ratings during 1999’s “sweeps week,” a pivotal time for television ratings. The show worked, thanks to a charismatic host in Regis Philbin and the high stakes of a big cash prize. That combination would be replicated with great success in reality competition shows, such as “American Idol,” which would follow.
