mainostajista

Mainostajista is the elative plural form of the Finnish noun mainostaja, which means advertiser. The base term mainostaja refers to a person or organization that pays for advertising to promote a product, service, or brand. In practice, the advertiser is typically a company, a brand owner, or another client, and is often contrasted with the advertising agency (mainostoimisto) that plans and executes campaigns on behalf of the advertiser. The form mainostajista is used when the sentence requires the elative case, for example after prepositions or verbs that convey movement from or reference to a source, and when discussing information or actions connected to several advertisers.

Usage in Finnish texts is common in research, market analysis, journalism, and marketing literature, where discussions center on data, opinions, or results related to multiple advertisers. The term signals that the subject matter concerns more than one advertiser, rather than a single entity.

Examples: "Tutkimuksessa tarkastellaan mainostajista kerättyä dataa." "Mainostajista saatu palaute vaikutti kampanjan suunnitteluun." These constructions illustrate how mainostajista functions grammatically to connect statements to the advertisers as a group.
