It was originally many things, but before going into the rubber goods business it started out as a paper mill. http://www.nokia.com/about-nokia/company/story-of-nokia/noki...

For some approximation of "originally". The rubber company had bought a cable company and an electricity company, and they merged in 1967. The electronics work came from the cable branch and the name from the electricity branch.

The phone company was spun off in 1979, and the telecommunications one in 1977, and the mother company later bought both. They sold off the non-phone, non-telco bits around the 90's, including nokia tyres (worth appx. 3.5 billion euros now).

According to Wikipedia, anyway.
