The top 10 neighbors for #Vikings span five distinct subcategories — TV Shows, TV Channels, Actors, TV Personalities, and Comedians — with scores compressed into a narrow band from 0.89 down to 0.86, the defining signature of a flat shape.
The Big Bang Theory leads at 0.89, followed immediately by History (the channel, not the show) at 0.89. That pairing is the first signal worth noting: the strongest audience overlap comes from a broad network sitcom and a cable channel, not from other historical dramas or period epics. Among the remaining eight neighbors, Rob Dyrdek (0.88) and Misha Collins — wait, Collins does not appear in the top 10. Correcting: Zak Bagans (0.87) and Jeff Dunham (0.87) round out the top five. Bagans and Aaron Goodwin (0.86) are both TV Personalities associated with paranormal programming, forming a small ghost-TV cluster within the set. Loudwire (0.86), a hard-rock website, is the only non-broadcast, non-personality entry in the top 10. The Dead Files (0.86) is the only other TV Show subcategory neighbor in the top 10 — and it is paranormal, not historical.
What the top 10 reveals is an audience that looks less like fans of a specific genre and more like a broad cable-and-network television crowd with a secondary lean toward paranormal and rock-adjacent content — a composition that cuts across genre lines rather than clustering tightly around historical drama peers.
