The main table includes all players who made their first appearance on Jeopardy! in 2019-20. Thus, they don't take into account:
The contestants in the 2020 College Championship are credited in the main table according to their given hometowns, not the location of their schools; a separate table at the bottom lists the school locations.
What's here:
Both challengers have hailed from the same media market on three occasions this season: September 26, October 9, and March 18 (all Washington, DC).
(Credits: Zap2it & TitanTV for TV schedules for each market; John Coryat (yes, that's actually the last name) for ZIP code maps; ThinkTV for a listing of Canadian market sizes, enabling me to rank them properly with the U.S. markets; and Ads for Carts for the lookup tools I use for both American and Canadian DMAs.)
Market size ranks are updated for 2019-20 (source: Nielsen Media Research).
Complete for all of Season 36 (2020-06-12), including the separate table for the Tournament of Champions, and a separate table for the College Championship contestants by location of their schools.
