Counts are active sponsored videos in our index (published in the last year), detected from public YouTube data via the official YouTube Data API. A sponsored video is one whose description or paid-promotion disclosure names the brand. A detected sponsorship is not confirmation of contract terms, and does not mean the brand is currently taking new creators.
