Nokia started as a paper mill in 1865 and diversified over time, producing various electronic devices including radios, TVs, and computers. It faced near bankruptcy after WWI but joined with other companies. From 1992 onward, it focused solely on telecommunications. It has faced challenges entering new markets, fierce competition, and struggles to expand. Nokia uses the Symbian operating system in many of its phones and acquired Symbian in 2008. However, critics say it offers poor after-sales service and was slow to enter the smartphone market. It also needs to ensure affordability and expand its product range and features to capture more markets.
