Where these numbers come from
- Sources are hand-picked by us for this market. Post and episode counts are everything we have indexed for them, back to whatever archive the source publishes.
- People, topics and advertisers are counted over the last 90 days only, so they describe what the collection is doing now rather than its whole history.
- A person is counted once per post, whether they wrote it, hosted it, or appeared on it as a guest. Podcast credits come from the transcript.
- Everything on this page is a live query against the corpus, refreshed hourly.
