The top 10 splits into two distinct neighborhoods: the Bachelor franchise's own sibling shows at the top, and a broader cluster of reality TV alumni and TV personalities just below — with Joanna Gaines and Chip Gaines as the most structurally surprising entries in the set.
Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 1.0 indicates near-identical audience shape. The Bachelorette leads at 0.99, followed by Bachelor in Paradise at 0.96 — the two franchise extensions that form the first, tighter peak. The second neighborhood is anchored by Reality TV Stars: Benjamin Higgins (0.95), JoJo Fletcher (0.93), Sean Lowe (0.93), Hannah Brown (0.92), and Tyler Cameron (0.92) — all franchise alumni whose audiences naturally mirror the show's own. What distinguishes the second peak is its tail: Chris Harrison (0.91) fits the franchise context, but Joanna Gaines (0.91) and Chip Gaines (0.91) are TV Personalities with no franchise connection, yet their audiences align closely enough to land in the top 10. All ten neighbors are either TV Shows, Reality TV Stars, or TV Personalities — no other subcategory appears in the top 10.
The two-peak structure reveals an audience that is tightly bound to its own franchise ecosystem at the top, then broadens into a wider TV-personality orbit that extends beyond the show's own cast.
