Category overview
Eight providers that get named when someone asks where to get audience data — set against each other on the criteria that actually decide a purchase. Every figure is the provider's own published claim, with the source given.
The providers on this page are not substitutes for one another, which is the single most useful thing to know before comparing them. They divide into four groups by method, and the group decides what kind of question the provider can answer at all.

Sources, retrieved 13 September 2026: YouGov Profiles · GWI · Nielsen Sports. Rascasse figures are our own published coverage. Where a provider publishes no comparable figure, the cell says so rather than carrying an estimate — we do not measure other providers' products.
There is no provider on this list that covers every question, and any comparison claiming otherwise is selling. Most serious audience programmes end up combining a panel source for attitudes with a behavioral source for reach, geography and partner selection. The useful decision is which of the two is missing today.
