FIAM, the Finnish Internet Audience Measurement, is the official measurement of online audiences in Finland. FIAM provides a wealth of information about audiences for sites, subsections, sales packs, or ad networks, as well as for different terminal devices and as a whole. FIAM was established at the beginning of 2017 and is run by a Subsidiary Group consisting of customers. The measurement also includes a Technical Group. FIAM's practical work is handled by Media Metrics Finland. The primary function of FIAM's activities is to promote the use of reliable and commonalized data on online audiences in Finland. FIAM is an agency that knows, defines and manages common standards for measuring online audiences. FIAM is not a Join Industry Committee (JIC) in the same way as Media Audit Finland, for example, because it does not own the measurement data purchased by its customers. It is a so-called hybrid model in which a commercial partner owns data and can commercialize it closely under agreed terms.
