Ken Jennings' ten nearest neighbors span comedians, actors, websites, and podcasts — with no other TV Personalities appearing in the top 10. The scores compress into a narrow band from 0.96 down to 0.94, confirming the flat shape: no single neighbor dominates, and the audience overlap is distributed evenly across a diverse mix of entity types.
Jon Stewart leads at 0.96, followed closely by actor Dan Levy at 0.96 and trivia and curiosity site Mental Floss at 0.96. Actor Bradley Whitford (0.95) and comedian Sarah Beattie (0.95) round out the top five. The remaining five — podcast The West Wing Weekly (0.95), satirical site The Onion (0.95), TV show Schitt's Creek (0.95), Chasten Buttigieg (0.94), and public radio program Wait Wait Don't Tell Me (0.94) — extend the pattern without breaking it. Comedians and actors account for four of the ten slots; websites and podcasts account for another four; a TV show and a professional fill the last two. The cross-kind character of the set is the defining feature: this audience's shape is shared most closely by wit-forward media properties and culturally engaged personalities, not by other game-show or quiz-format figures.
The flat distribution across subcategories suggests an audience that is broadly curious and media-literate rather than narrowly organized around any single genre or personality type.
