BlackBerry Limited
BlackBerry Limited is a Canadian software company specialising in secure communications and IoT. It was founded in 1984 as Research In Motion (RIM) and developed the BlackBerry brand of wireless mobile devices from 1999 to 2016. After spinning off its mobile division into BlackBerry Mobile in 2016 — discontinued in 2020 — the company transitioned to providing software and services and holds critical software application patents. RIM was the first wireless data technology developer in North America and the first outside the Nordic countries to develop Mobitex connectivity products. In 1996, RIM introduced the Interactive Pager, the first two-way messaging pager. In 1999, RIM introduced the BlackBerry 850 pager, the first device to use the BlackBerry OS, which received push email from Microsoft Exchange Server using BlackBerry Enterprise Server (BES). Its introduction set the stage for enterprise-oriented products, such as the BlackBerry 957 in April 2000, the first BlackBerry smartphone.
