The Late Show's nearest audiences are activists, journalists, and politicians — not other TV shows.
Across the top 10 neighbors, the similarity scores form a tight band from 0.97 (David Hogg) down to 0.96 (March For Our Lives), with no single neighbor pulling away from the rest — the defining characteristic of a flat shape. The subcategory breakdown tells the story: activists lead the set (David Hogg, 0.99; Sarah Chadwick, 0.98; Charlotte Clymer, 0.97), followed by politicians (Pete Buttigieg, 0.98; Robert Reich, 0.98; Rep. Katie Porter, 0.97) and journalists (Aaron Rupar, 0.98; Daniel Dale, 0.98; Steve Kornacki, 0.97). The one organization in the set, March For Our Lives (0.97), falls under Activism — consistent with the rest of the cluster. Comedians appear only at the margins: Sarah Cooper at 0.97 is the sole comedian in the top 10. No other TV show appears in the top 10 at all, making The Late Show a cross-kind outlier in its own neighborhood — its audience shape is defined almost entirely by political and civic figures rather than entertainment peers.
The flat distribution across this politically oriented cluster suggests an audience whose attention is broadly organized around civic engagement, with the show functioning as one node in a wider network of political media consumption rather than as the center of an entertainment-first audience.
