katselijoiden

Katselijoiden is the genitive plural form of the Finnish noun katselija, meaning viewer, spectator, or observer. The term is used to indicate something that belongs to or concerns the group of viewers, such as "katselijoiden määrä" (the number of viewers) or "katselijoiden mielipiteet" (the viewers’ opinions). In media, events, and online platforms, katselijoiden commonly refers to the audience as a collective rather than to individuals.

Etymology and usage: Katselija comes from katsella, “to watch,” with the genitive plural suffix -iden, producing katselijoiden. The form is used to express possession or related attributes of the viewing audience. It is closely related to katsoja/katsojat, which are more typical for television audiences, while katselija is a somewhat broader term for any watcher or observer.

Declension note: In singuar, the forms are katselija (nominative) and katselijan (genitive); in plural, katselijat (nominative) and katselijoiden (genitive). Partitive forms are katselijaa (singular) and katselijoita (plural).

See also: katsoja, katselija, yleisö. These terms are often used interchangeably depending on context, with subtle differences in emphasis on watching behavior versus audience as a social group.
