The two strongest pulls in Jeremy Clarkson's similarity graph are James May (0.95) and Richard Hammond (0.94) — his two longtime co-hosts — forming a tight cluster that sits well above every other neighbor in the top 10. That gap is the defining structural feature here: the next closest neighbor, The Grand Tour at 0.88, is a full seven points lower, and the remaining seven neighbors compress into a band between 0.80 and 0.76.
The shape is two-peak in the sense that the top 10 splits into two distinct neighborhoods. The first is the automotive TV cluster: May, Hammond, and The Grand Tour (all TV Personalities or TV Shows), plus Top Gear at 0.75 — the show that originally united all three. The second neighborhood is a Barstool Sports orbit: Dave Portnoy (0.80), Kayce Smith (0.79), Barstool News Network (0.77), Starting 9 (0.77), and Dan Katz (0.76) — a mix of Professionals, TV Personalities, and Podcasts and Radio. Life is Good, a Fashion brand at 0.77, is the one outlier that fits neither cluster cleanly. Clarkson's own subcategory — TV Personalities — accounts for three of the top 10 neighbors (May, Hammond, Smith), but the Barstool contingent represents a genuinely cross-kind pull, suggesting the audience bridges British motoring television and American sports-media fandom.
The overall picture is an audience with a very specific core — one that follows the Grand Tour trio closely — but with a secondary gravitational pull toward irreverent, personality-driven American sports media.
