A Canadian tech company best known for the QNX software that runs inside cars, medical devices, and industrial robots — powering the digital dashboards of vehicles from top automakers. Born in 1984 as Research In Motion (RIM) above a Waterloo pizza shop, it became famous for its physical-keyboard smartphones, then pivoted to secure communications and patent licensing. The "BlackBerry" name was coined by a branding agency in 1998 because the device's tiny QWERTY keys resembled the seeds of a blackberry.
