Which product did Nokia, the telecommunications company, originally sell?

The statement that Nokia originally sold paper products is incorrect. Nokia, a telecommunications company founded in 1865, originally started as a pulp mill producing wood pulp for use in making paper. However, by the 20th century, Nokia expanded into various industries such as rubber, cables, electronics, and eventually mobile phones. Nokia's shift from producing paper to becoming a leading mobile phone manufacturer occurred due to evolving market demands and technological advancements.
