StoryCorps

StoryCorps' top 10 neighbors form a dense, undifferentiated cluster — scores run from 0.978 down to 0.970, a spread of less than one percentage point — with no single neighbor pulling away from the rest.

The shape is flat, and the composition of the cluster tells the real story. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 0.97 across all ten positions means the audience shape is remarkably consistent across a wide range of entity types. The top neighbor is ProPublica (0.978), a non-profit organization, followed immediately by This American Life (0.978) and NPR's Planet Money (0.974), both podcasts and radio — the same subcategory as StoryCorps itself. But the cluster doesn't consolidate around that subcategory. Radiolab (0.973) and Crooked Media (0.973) are also podcasts and radio, making five of the top ten from that subcategory. The remaining five cross into other kinds entirely: Jon Lovett (0.972) is a comedian, Slate (0.971) a website, Jon Favreau (0.971) a professional, Ira Glass (0.971) a journalist, and Vox (0.970) a news publisher. That mix — public-radio podcasts alongside political media figures, a non-profit, and a news-analysis outlet — points to an audience defined less by format than by a consistent orientation toward public-affairs and civic content across multiple channels.

The flat shape, with its narrow score band and mixed subcategory composition, suggests StoryCorps draws an audience that is broadly shared with a recognizable ecosystem of left-leaning public media and civic journalism rather than clustering tightly around any single format or figure.
