Nokia may have been gradually building out its mapping empire for more than 10 years, but it’s only now preparing to really ramp up its presence in the mobile navigation realm as it prepares to launch for Android and iOS this year, only months after selling its Devices and Services division to Microsoft. But how did it all begin? Here’s a quick summary of how Nokia’s efforts have come to fruition. The Finnish tech titan’s mapping efforts started to take shape in 2001 with its involvement in TellMaris, a consortium that pushed the Smart2Go 3D map interface, before Nokia went on to gain the rights to the software through its acquisition of mapping, routing and navigation company Gate5 in 2006. The following year, Nokia revealed it was making the Smart2Go application free to download for select Nokia and Windows Mobile devices, bringing mapping and routing to 150 countries, with turn-by-turn navigation in more than 30 markets.
