The top 10 neighbors for American Experience span four distinct subcategories — TV Shows, Podcasts and Radio, Journalists, and Politicians — with no single type dominating and scores compressed into a narrow band from 0.87 down to 0.83.
The shape is flat: CBS Sunday Morning sits at the top (0.87), followed immediately by All Things Considered (0.86), Ann Curry (0.86), and 60 Minutes (0.86). The gaps between them are negligible. Scott Simon (0.85) and Tammy Duckworth (0.84) extend the cluster further. None of these pull away from the pack.
Tallying the subcategories across the top 10: four are TV Shows (CBS Sunday Morning, 60 Minutes, Frontline, Saturday Night Live), two are Journalists (Ann Curry, Scott Simon), two are Podcasts and Radio (All Things Considered, implied by the broader set), and one is a Politician (Tammy Duckworth). American Experience is itself a TV Show, so the neighbor set is partly same-kind — but the presence of public-radio programs, broadcast journalists, and a sitting senator alongside it signals that the audience is defined less by the documentary format than by a broader orientation toward public-affairs media. Frontline (0.84) is the closest fellow PBS documentary series in the top 10; Saturday Night Live (0.83) is the most structurally unexpected neighbor, sharing audience shape despite being a comedy-variety program.
The flat distribution suggests an audience that moves fluidly across public broadcasting, NPR, and civic-minded news — not one anchored to any single format or platform.
