The primary analysis covers 2,200+ active English-language NBA podcasts in 2026, where "active" is defined as any show with at least one episode published in 2026 as of the June 2026 snapshot date. Inactive shows, foreign-language shows, and shows outside the NBA topic boundary are excluded from the trend analysis but may appear in the global-context section.
What counts as an "NBA podcast." The universe is the union of (a) pure-NBA shows whose content is overwhelmingly basketball-focused and (b) broader sports / pop-culture shows whose catalog includes substantial, recurring NBA coverage (e.g., The Bill Simmons Podcast, Mostly Hoops). Inclusion was driven by an automated NBA-relevance classifier applied to each show's metadata and recent episode signals. This is a permissive boundary by design, it captures the show-level conversation around the league as listeners actually encounter it, not only podcasts that cover nothing else. Readers should keep this in mind when interpreting the top of the leaderboard: a few flagship shows are general-sports properties that anchor a large share of NBA listening but are not exclusively NBA.
Show-level deduplication uses RSS feed identifier as the primary key, with podcast title as a fallback for entries that lack a stable feed ID. Where multiple rows describe the same show, listener counts use the maximum value, ratings take the mean, and binary flags (sponsor, guests, video) take the logical OR.
On sample sizes. Dataset A contains 2,215 deduplicated active English-language NBA podcasts, this is the canonical population, displayed throughout as "2,200+". Individual subsections analyze smaller subsets where metadata availability differs: 1,968 shows carry a modeled listener estimate (used for reach tiers and monetization-by-scale), and ~2,150 shows publish audience-composition data (used for demographics). These are not competing totals, they are coverage subsets of the same 2,215-show universe, and each chart labels its own n-size where it differs from the full population.
Show format (solo / duo / panel) is inferred from the number of distinct host or contact rows associated with each feed, one row is read as solo, two as duo, three or more as panel. Because the dataset captures listed contacts rather than a verified on-air host count, a show with a single listed contact but multiple actual hosts can be coded as "solo." The reported solo share (~67%) should therefore be treated as an upper bound, with the true duo and panel shares likely modestly higher.
