In Short

Nokia, the Finnish company, has been well know in the mobile phone industry for years. First founded back in 1865, Nokia has introduced a number of products to the mobile industry, from candy bar dumb phones to Windows powered smartphones. Back in 2011, Nokia entered a pact with Microsoft to exclusively use its Windows Phone platform on all future smartphones.

Fast forward from 2011 to September 2013, and Microsoft decided to acquire Nokia's mobile phone business as part of a deal worth just over $7 billion USD. Several of Nokia's key executives joined Microsoft when the deal finalized in April 2014, and then in November 2014 Nokia began licensing product designs and technologies to third-party manufacturers. Microsoft slowly began laying off some of the excess employees, and changing the Nokia branding of the smartphones to its own.

While the Nokia we knew was purchased by Microsoft and much of it has since disappeared from the consumer spotlight, Nokia has confirmed it has plans to get back into the mobile indusry and make some new phones. In April 2015, Nokia acquired Alcatel-Lucent in a deal worth $16.6 billion, and the deal is still awaiting final approvals.

In August 2015, Nokia sold its HERE mapping business to Audi, BMW and Daimler in a deal valued at $3 billion.
