A brand appears here only when an ad read for it was detected in an episode of OK Let’s Learn that we have transcribed. It is not a complete record of the show’s advertisers: we do not transcribe every episode, and dynamically inserted ads differ between listeners. Host-read share counts only the reads we could classify. Each quote is the transcript, verbatim, linked to the moment in the episode.
