Microsoft has confirmed that it has acquired the London-based startup SwiftKey, maker of the popular predictive smartphone keyboard of the same name. According to a press release, development for both iOS and Android platforms will continue, even as Microsoft explores “scenarios for the integration of the core technology across the breadth of our product and services portfolio.” Microsoft is believed to have paid about £170 million ($250 million) to acquire SwiftKey. The acquisition is neither a new nor unexpected development for Microsoft.
