The Bloomberg article said that Nokia was founded near the city of Tampere. In fact, it was founded in a smaller town near Tampere, called... Nokia. Originally it would have been called something to "the Nokia wood pulp company" or whatever, but they kept the name Nokia when they expanded and moved.
Nokia's headquarters have been in the city of Espoo for a long time (near Helsinki). The area in Espoo where they have their office, Otaniemi, is home to many Helsinki-area tech companies, Aalto University, and many science and engineering institutions.
