How this list is built
The scope is channels we classify as science. We order them by subscriber count as reported by YouTube, refreshed nightly, and show the top 50. A sponsor is a brand we detected in that channel's videos through sponsor segments, description disclosures and promo links; the count is unique brands, all time. Channels we have not indexed are not ranked, so a missing channel means missing coverage, not a judgement. Read the full methodology.
