Ask This Old House is the overwhelming anchor of This Old House's similarity graph, scoring 0.91 — a gap of nearly 0.13 points above the second-nearest neighbor. That separation defines the spike shape: one dominant pull, then a long tail of moderately similar audiences.

What makes the tail striking is its composition. Of the remaining nine neighbors in the top 10, none share This Old House's subcategory (Blogs), and none are home improvement properties. Instead, the cluster is built almost entirely around golf and sports media. SportsLine sits at 0.79, Nike Golf at 0.78, and Life is Good at 0.78. Scott Walker (0.78, Politicians) and Keegan Bradley (0.77, Athletes) follow closely, with Dustin Johnson (0.77) and Rory McIlroy (0.76) extending a run of PGA-adjacent figures. Golf Central (0.76) and PGA Tour (0.75) round out the ten. Athletes account for four of the ten neighbors; the broader sports-and-golf cluster accounts for the majority of the set.

The picture that emerges is an audience tightly bonded to its companion show, but whose broader shape is defined by golf fandom and sports media consumption — not by home improvement content.
