Frontline's nearest audiences span news publishers, activism organizations, podcasts, magazines, and fellow TV shows — with no single neighbor pulling far ahead of the rest.

The shape is flat: the top 10 similarity scores run from 0.97 (Women's March) down to 0.97 (The Associated Press), a band of less than one percentage point. NPR (0.97) and PBS NewsHour (0.97) are the closest channel-type neighbors — one a podcast/radio brand, the other the only fellow TV Show in the top 10. The remaining eight positions are occupied by activism organizations (Media Matters, 0.97), non-profits (ProPublica, 0.97), news publishers (Politico, 0.97; The Associated Press, 0.97), a magazine (The Chronicle of Philanthropy, 0.97), and another TV Show (The Daily Show, 0.97). Tallying subcategories across the top 10: two TV Shows, two News Publishers, two Activism organizations, one Podcasts and Radio, one Non-Profit, one Magazines, and one additional News Publisher — a genuinely mixed set with no dominant subcategory.

What the flat shape reveals is that Frontline's audience is not defined by loyalty to a single media format or organizational type, but by a consistent orientation toward public-interest journalism, civic activism, and policy-focused media across multiple channels.
