HGTV (0.85) and Drew Scott (0.84) form two distinct poles in Property Brothers' similarity graph — the channel that airs the show and one of its hosts — and the gap between them and the rest of the top 10 is the defining structural feature here.
The shape is two-peak: those first two neighbors pull noticeably ahead of the field, with Jonathan Scott close behind at 0.84, then a step down to Gary Sinise at 0.80 and Guy Fieri at 0.79. Below that, the remaining neighbors — Harry Connick Jr (0.78), Keyshawn, JWill & Zubin (0.77), Brandon Tatum (0.77), Zondervan Publishers (0.77), and Pro Football Rumors (0.77) — cluster tightly within a narrow band. By subcategory, TV Personalities dominate the top 10: Drew Scott, Jonathan Scott, Guy Fieri, and Harry Connick Jr. all carry that label, alongside the TV Channel HGTV. The remaining five span Actors, Musicians and Bands, Podcasts and Radio, Activists, Book Publishers, and Blogs — a cross-kind spread that signals the audience is not defined solely by home-renovation content. Property Brothers is the only TV Show in its own top 10; no fellow TV Show appears among these nearest neighbors. The presence of a sports radio podcast, a conservative activist, and a Christian book publisher alongside HGTV and the Scott brothers suggests an audience whose shape is as much about a broader lifestyle and values profile as it is about the show's genre.
The two-peak structure — network on one side, individual hosts on the other — reflects an audience that organizes around both the brand and the people, with a wide secondary ring that extends well beyond home improvement.
