Where this comes from

Book a Sponsor reads published newsletter issues and records an ad when an issue shows one: a sponsor label, a tracked link or ad copy. Only ads from the last 90 days count, and each brand is counted once per issue. We do not see what a brand paid. Political, adult and non-English newsletters are left out, and so is a brand we cannot tie to a company. Read Oct 2, 2026, rebuilt every day.
