Jeopardy! The Greatest of All Time

Jeopardy! The Greatest of All Time was a special tournament series of the game show "Jeopardy!" that took place in January 2020. The tournament was produced for ABC and aired on the network in prime time; this was the first time any "Jeopardy!" competition aired on network television since 1990, when the special tournament series "Super Jeopardy!" was carried by ABC.
The tournament featured former champions Ken Jennings, Brad Rutter, and James Holzhauer competing for a $1 million top prize and the recognition of being the show’s greatest champion of all time.
Jennings won the tournament on January 14, 2020, with Holzhauer finishing second and Rutter third. With the $1 million prize added to his previous winnings across several game show appearances, Jennings surpassed Rutter as the highest-earning American game show contestant of all time, a record he had previously held twice. 
Format.
The tournament began on January 7, 2020, and each match consisted of two games. Each game was played as normal with the Jeopardy! and Double Jeopardy! rounds followed by Final Jeopardy!; the exception was that the scores were in points and not dollars. The contestant with the highest combined score from the two games would win the match, and the first one to three match wins won the tournament.
Production.
On November 18, 2019, ABC announced that the three highest-earning "Jeopardy!" contestants of all time—Jennings, Rutter, and Holzhauer—would compete in a best-of-seven prime-time tournament, "Jeopardy! The Greatest of All Time". The first contestant to win three matches receives the title and a grand prize of $1 million; the others receive $250,000 each. The series was produced by Sony Pictures Television, with Harry Friedman executive producing and Alex Trebek hosting. This is the first time "Jeopardy!" has aired on network television instead of in syndication since ABC carried 1990's "Super Jeopardy!" tournament. ABC Owned Television Stations group has been the lead broadcaster of the syndicated version for most of its run. In addition to ABC, the tournament was broadcast in Canada on Yes TV and two of its partner stations, CHEK and NTV, all of which also carry the syndicated version. The series began taping on December 10, 2019.
