BlackBerry OS is a discontinued proprietary mobile operating system developed by Canadian company Research In Motion (now BlackBerry Limited) for its BlackBerry line of smartphone handheld devices. The operating system provides multitasking and supports specialized input devices adopted by BlackBerry for use in its handhelds, particularly the trackwheel, trackball, and in later years, the trackpad and touchscreen.
Research from June 2011 indicated that approximately 45% of mobile developers were using the platform. BlackBerry OS was discontinued after the release of BlackBerry 10 in January 2013, and support for it ceased on January 4, 2022.
