Nokia's fall: from 40% market share to Microsoft sale

Nokia, once the world's dominant mobile phone maker with nearly 40% global market share and annual sales of 400 million phones, sold its handset business to Microsoft in 2014 for $7.2 billion. The Finnish company's rise began with CEO Jorma Ollila's gamble on GSM technology, transforming it from a conglomerate of rubber and paper products into a tech giant. But within seven years of its peak, Nokia lost its market leadership after ignoring internal innovations like touchscreen prototypes.
