At the turn of the 1990s, Tampere's industry underwent a major structural change, as the production of Tampella's and Tampere's textile industry in particular was heavily focused on bilateral trade with the Soviet Union, but when it collapsed in 1991 the companies lost their main customers. As a result of the sudden change and the depression of the early 1990s, Finlayson and the Suomen trikoo had to reduce their operations sharply. Tampella went bankrupt. But although the change left a huge amount of vacant industrial space in the city center, in the early 2000s it was gradually put to other uses, with the current Tampere cityscape being characterized above all by strong IT companies, most notably Nokia's Tampere R&amp;D units.
