Doctor Who on BBC America (0.83) and Bruce Campbell (0.82) sit nearly level at the top of Doctor Who's similarity graph — two distinct poles that together define the shape of this audience.
The first pole is straightforward: Doctor Who on BBC America is the only other TV Show in the top 10, and its score of 0.83 reflects near-identical audience composition between the two channel presences for the same property. The second pole is more revealing. Bruce Campbell at 0.82 is followed closely by Jonathan Frakes (0.79) and Nathan Fillion (0.77) — all subcategorized as Actors — making actors the dominant neighbor type in the top 10. Weird Al Yankovic (0.78) is the lone Musician in the set, and Critical Role (0.78) represents Podcasts and Radio. Rounding out the top 10 are Diablo (0.77) and Star Trek (0.77) — a Video Game Franchise and a Movie Franchise respectively — alongside Alan Tudyk (0.74) and Michael Dorn (0.74), both Actors. That gives the top 10 five Actors, one Musician, one Podcast, one TV Show, and two franchise Brands — a cross-kind cluster anchored heavily in genre-adjacent celebrity rather than fellow TV properties.
The two-peak structure — one peak in same-property TV, one in cult-adjacent actors and genre franchises — suggests this audience is shaped less by television habits broadly and more by a specific fandom orientation that crosses media formats.
