Microsoft confirmed it will be dropping the Nokia and Windows Phone brands, all future product will adopt the Microsoft Lumia branding. It's a slow transition but it's not unexpected because Nokia is still a separate company that focuses on mapping and network infrastructure. As part of the acquisition deal, Microsoft was allowed to continue to use the Nokia brand for a while but they don't have the rights to continue to use it indefinitely.
Microsoft started dropping hints about its plans to kill off the Nokia and Windows Phone brands last month, and now the company is ready to make it official. Microsoft Lumia is the new brand name that takes the place of Nokia for the software maker. The name change follows a slow transition from Nokia.com over to Microsoft's new mobile site, and Nokia France will be the first of many countries that adopt "Microsoft Lumia" for its Facebook, Twitter, and other social media accounts. Microsoft has confirmed to The Verge that other countries will follow the rebranding steps in the coming weeks.
