Nokia was #1 in phones, then bet everything on Windows Phone and lost the smartphone era

For a decade from 1998, Nokia was the world's largest mobile-phone maker, at one point holding around 40% of the global handset market and more than half the smartphone market. Then the iPhone arrived in 2007 and Android in 2008, and the industry shifted from hardware to software ecosystems — exactly where Nokia's aging Symbian platform was weakest. Nokia's share began a steep, sustained decline.

In February 2011, new CEO Stephen Elop sent an internal memo that was soon leaked: he described Nokia as standing on a 'burning platform' over an oil rig, and said the company had to 'jump' into a new ecosystem. Days later, Nokia announced it would abandon its own operating systems and bet its smartphone future entirely on Microsoft's Windows Phone. It was a decision to tie the world's biggest phone maker to a platform with a tiny share, in the hope the two underdogs would rise together.

The bet failed. Windows Phone never gained meaningful traction against iOS and Android, and Nokia's smartphone sales collapsed while it waited for the new platform. In 2014, Microsoft bought Nokia's phone business outright. A company that had defined an industry was reduced to licensing its brand and patents. The 'burning platform' memo is now taught as a vivid diagnosis — and a warning that the jump you choose can be as fatal as the fire you're fleeing.
