CACI Acorn
In practice, for a UK buyer
The paragraph above is the neutral answer. This is the part a vendor glossary leaves out.
The intended basis for ranking cinema venues by how far their catchment over-indexes on a target audience. Stated plainly: we do not hold that licence. Cinema venue lists are currently built from the persona's own postcode districts, the catchment over-index figures shown on a sandbox booking brief are deterministic fixtures rather than data, and the Acorn adapter is a fail-closed stub. The supply page grades it accordingly.

What this one connects to
Most confusion in media buying comes from two adjacent terms being used interchangeably, so these are the neighbours worth reading next.
Cinema advertising
Advertising shown on cinema screens before a film, sold by audience packs, film genre and venue rather than by individual viewer. Delivered as a Digital Cinema Package and subject to its own age-rating clearance separate from broadcast clearance.
Experian Mosaic
A UK geodemographic classification that assigns every household to one of a set of named types based on demography, affluence, life stage and location. Used to select households for addressable television and direct media.
More on targeting and identity
How an audience is described to a seller, and how much of the description survives. Most of the honest difficulty in media buying lives here.
45 minutes. Bring a real brief and we compile it live. You describe one audience and watch it compile into seven targeting specifications, each with the score for how much of the definition survived.
