Nokia rose to become the dominant mobile phone company capturing a large share of the market in the late 20th century by producing affordable and easy to use phones. However, competitors like Apple and Samsung emerged in the early 21st century introducing smartphones running on new operating systems like iOS and Android. Nokia failed to keep up with this transition and technological changes, sticking to its existing platform. It lost significant market share and was eventually acquired by Microsoft in 2013, marking the demise of the once leading mobile company.
