The MikroMikko series proved that Nokia could manage complex supply chains involving semiconductors, displays, and plastic molding. This era fostered a generation of Finnish engineers who understood the intricacies of digital logic, a workforce that would become invaluable in the late 1980s and 1990s.
By the early 1970s, the global market saw the emergence of the electronic calculator. This device became the "killer app" for integrated circuits. Recognizing an opportunity to diversify beyond low-margin cable production, Nokia merged its electronics operations with the manufacturing capabilities of its other divisions. This led to the production of consumer electronics, most notably calculators, under the Nokia brand.
Early Nokia calculators were characterized by a distinctly Scandinavian design philosophy: functional, boxy, and durable. calculator nokia
