radiolinja's original investors included the finnet group, a consortium composed of a number of finnish corporations and local telephone companies. in the mid-1990s, elisa (known then as helsinki telephone ltd) began acquiring a greater stake in radiolinja, ultimately leading to the mergers of radiolinja, radiolinja origo, and elisa. at this point, elisa had also acquired some of radiolinja's other major stakeholders, such as soon communications (previously tampere telephone plc and before that tampere telephone cooperative).
