MythBusters' nearest neighbors span TV personalities, comedians, actors, video game franchises, and fellow TV shows — with no single entity pulling far ahead of the rest. Similarity here measures how closely two entities' audiences resemble each other in composition; the top 10 scores run from 0.85 down to 0.80, a narrow band that defines the flat shape.
The top of the list is anchored by the Impractical Jokers universe: Impractical Jokers leads at 0.85, followed immediately by its cast members Brian Quinn (0.84) and James Murray (0.84), then comedians Sal Vulcano (0.83) and Joe Gatto (0.83). That cluster — a single show plus four of its personalities — accounts for five of the top ten slots, making it the most coherent signal in the set. The remaining five positions are occupied by Fuller House (0.82), TV personality Rhett & Link (0.81), comedian Daniel Tosh (0.81), actor Hayden Panettiere (0.81), and World of Warcraft (0.80). That last entry — a video game franchise — is the one genuine cross-kind outlier in an otherwise celebrity-and-TV-heavy set. No other TV show shares MythBusters' own subcategory in the top 10 beyond Impractical Jokers and Fuller House.
The overall picture is an audience shaped primarily by ensemble comedy and TV personality fandom, with a secondary pull toward gaming that becomes more visible further down the neighbor list.
