Nova PBS's top 10 nearest neighbors are a mix of public-radio programs and NPR journalists — not other TV shows, and not science-specific media alone.
The shape is flat: scores run from 0.91 (Morning Edition) down to 0.90 (Wait Wait Don't Tell Me), a span of less than two points. No single neighbor dominates. Five of the ten are Podcasts and Radio: Morning Edition (0.91), Science Friday (0.91), NPR Science Desk (0.91), Marketplace (0.91), and Hidden Brain (0.90). Three are Journalists: Tamara Keith (0.90), Audie Cornish (0.90), and Nina Totenberg (0.90). The remaining two are March For Science (0.90), an Activism organization, and Wait Wait Don't Tell Me (0.90), another Podcasts and Radio entry. Last Week Tonight (0.88) is the only other TV Show in the broader neighbor set visible here, appearing well outside the top 10. Within the top 10 itself, Nova PBS is the sole TV Show — the audience shape it carries belongs almost entirely to the public-radio and NPR-journalist world, with a secondary signal from civic and science-adjacent media.
The overall picture is an audience defined less by the television format Nova PBS occupies and more by the public-media ecosystem it shares with NPR's programming and on-air talent.
