Masterpiece PBS's nearest audiences span a notably mixed cluster — fact-checking websites, book platforms, NPR programs, politicians, and comedians — with no single neighbor pulling far ahead of the rest.
The shape is flat: scores run from 0.88 (Snopes.com) down to 0.81 (Nova PBS) with no sharp drop-off between them. Goodreads (0.86) and Mental Floss (0.85) sit just behind Snopes, both websites oriented toward reading and curiosity. Anne Lamott (0.85), an author, is the only author in the top 10. The politician subcategory is the most represented: Amy McGrath (0.85), Sherrod Brown (0.85), and Claire McCaskill (0.84) all appear, making politicians the dominant neighbor kind despite Masterpiece PBS being a TV show. Morning Edition and Ken Jennings (both 0.84) round out the top 10 alongside Jeff Bridges (0.84), an actor, and Ken Jennings as a TV personality. Notably, Nova PBS (0.81) is the only other TV show in the top 10 — the center entity's own subcategory appears just once among the ten nearest neighbors.
The overall picture is an audience shaped more by public-media consumption habits and civic engagement than by television genre affinity.
