# Get publishers ranked by exposure to a brand-safety category

> For one of the 12 GARM brand-safety categories, returns a paginated ranking of podcast publishers by exposure across their catalog. The killer view for regulated brands: an alcohol advertiser pivots on illegal_drugs_alcohol_tobacco and immediately sees which publishers carry the highest catalog-level exposure (and at what prevalence + treatment); a family brand pivots on adult_sexual or hate_speech_aggression to build an exclusion list. min_prevalence + treatment narrow what counts as 'exposed'. Each row includes prevalence + treatment breakdowns and up to three example podcasts in the publisher's catalog that exhibit the highest exposure.
