1865 – presentNokiaNokia — founded in 1865 as a wood pulp mill on the banks of the Nokianvirta river in Finland — is one of the most dramatic corporate transformation stories in history. From paper to rubber boots to cables to consumer electronics to mobile phones, Nokia reinvented itself repeatedly. At its peak in 2000 it was the most valuable company in Europe and accounted for 4% of Finland's entire GDP. Its collapse after the iPhone's arrival and its sale of the mobile division to Microsoft in 2013 is one of the great corporate falls. Today Nokia survives as a major telecommunications infrastructure company.
1865Nokia founded as paper millFredrik Idestam founds a wood pulp mill on the Nokianvirta river in southern Finland in 1865, naming it Nokia Ab after the river.

The Nokia name comes from the river, which may derive from the Finnish word for the dark, furry European mink once native to the riverbanks. The connection between a 19th-century Finnish paper mill and the mobile phone that will define an era is almost impossible to imagine.
