Who Wants to Be a Millionaire (American game show)

Who Wants to Be a Millionaire (often informally called Millionaire) is an American television game show adapted from the same-titled British program created by David Briggs, Steven Knight and Mike Whitehill and developed for the United States by Michael Davies. The show features a quiz competition with contestants attempting to win a top prize of $1,000,000 by answering a series of multiple-choice questions, usually of increasing difficulty. The program has endured as one of the longest-running and most successful international variants in the Who Wants to Be a Millionaire? franchise.
The original U.S. version premiered on ABC on August 16, 1999, as part of a two-week daily special event hosted by Regis Philbin. After this and a second two-week event aired in November 1999, ABC commissioned a regular series that launched on January 18, 2000 and it remained since then. Philbin hosted the entire run of the original network series as well as two additional special event series that aired on ABC in 2004 and 2009. On April 9, 2015, one month before the finale of the Daytime Version, ABC announced that it had picked up a new primetime incarnation of Millionaire, premiering on June 21, 2015 and hosted by comedian Jimmy Kimmel (who is also a co-executive producer of the show) with celebrity contestants. 
A daytime version of Millionaire began airing on ABC on September 16, 2002, and was initially hosted by Meredith Vieira. Cedric the Entertainer took over the show in 2013 following Vieira's departure, with Terry Crews replacing him in 2014 and hosted until the Daytime version was canceled, with the finale airing on May 29, 2015.
The show has had numerous format and gameplay changes over its runtime and, since its debut, twelve contestants have answered all questions correctly and won the top prize. As the first U.S. network game show to offer a million-dollar top prize, the show made television history by becoming one of the highest-rated game shows in the history of U.S. television. The U.S. Millionaire won seven Daytime Emmy Awards, and TV Guide ranked it No. 6 in its 2013 list of the 60 greatest game shows of all time.
