TED Radio Hour's nearest audiences span journalists, fellow podcasts, academics, and comedians — a mixed cluster compressed into a narrow band between 0.94 and 0.96, with no single neighbor pulling sharply ahead.
The shape is flat: the top score belongs to Nina Totenberg at 0.96, but Marketplace (0.96), Tamara Keith (0.95), Kevin M. Kruse (0.95), and Morning Edition (0.95) are all within a fraction of a point. Tallying the subcategories across the top 10: four are Podcasts and Radio (Marketplace, Morning Edition, Hidden Brain, Fresh Air), three are Journalists (Nina Totenberg, Tamara Keith, Ari Shapiro), one is an Academic (Kevin M. Kruse), one is a Podcast and Radio entry (Pod Save America), and one is a Website (Five Thirty Eight). The dominant subcategories are Podcasts and Radio and Journalists — but the presence of a data-journalism website and a political podcast alongside public-radio staples signals that the audience shape is defined less by format than by a consistent orientation toward news, analysis, and ideas. TED Radio Hour's own subcategory, Podcasts and Radio, accounts for five of the ten neighbors, so the audience does overlap substantially with its own kind — but journalists are nearly as prominent, making this a cross-kind cluster as much as a same-kind one.
The flat distribution here reflects an audience whose shape is broadly shared across the public-radio and civic-media ecosystem, with no single neighbor standing apart as a defining anchor.
