Rick and Morty sits at the top of Philip DeFranco's similarity graph at 0.83 — the strongest pull in the top 10, and the only TV show among them. Similarity here measures how closely two entities' audiences resemble each other in composition; a score of 0.83 means the audiences are shaped nearly alike, regardless of what the entities actually are.
The shape is two-peak. The first peak is that TV show: Rick and Morty at 0.83 stands noticeably above the rest. The second peak is a tight cluster of gaming properties — Pokémon GO at 0.81, Overwatch at 0.81, and Pokémon at 0.76 — all Video Game Franchises or Entertainment brands with gaming identities. Rounding out the top 10 are Ethan Klein (Comedians, 0.77), Discord (Social Media, 0.76), Niantic, Inc. (Game Developers, 0.76), Isabelle (Fictional Characters, 0.75), Funko (Toys and Games, 0.75), and Pokémon GO News (Video Game Franchises, 0.74). No other Tech Personalities — DeFranco's own subcategory — appear in the top 10.
The overall picture is an audience bridging animated adult comedy and gaming culture, with a single comedian (Ethan Klein) as the lone non-gaming, non-TV personality in the set.
