Where this list comes from. The seed shows carry a publisher-reach figure and a published contact from a media-database export. The agent-discovered shows are pulled live from Apple’s public index across ~30 niche searches — name, publisher, genre, episode count and, where the show is currently charting, its real UK Top-100 rank. No listener/download numbers are invented: prominence is chart rank where we have it, and the honest next step is to anchor every show with a normalised popularity score (Podcastindex + Apple ratings are free; Listen Notes / Podchaser add a real 0–100 score). Contacts shown are only those an outlet publishes itself.
